    Before: TATEL and PILLARD, Circuit Judges, and
    SENTELLE, Senior Circuit Judge.
    Opinion for the Court filed by Circuit Judge TATEL.
    TATEL, Circuit Judge: Almost four decades ago, in
    N.L.R.B. v. Yeshiva University, 
    444 U.S. 672
     (1980), the
    Supreme Court sustained the National Labor Relation Board’s
    extension of the protections of the National Labor Relations
    Act to the faculty of private universities. The Court concluded,
    however, that the full-time faculty seeking recognition in that
    case qualified as managerial employees exempt from the
    NLRA’s coverage because, as at other “‘mature’ private
    universit[ies]” where “authority . . . is divided between a
    central administration and one or more collegial bodies,” the
    faculty at Yeshiva exercised “effective[] control” over central
    university policies. 
    Id. at 680, 683
    . In this case, the Board,
    applying standards it set forth in its post-Yeshiva decision,
    3
    Pacific Lutheran University, 
    361 N.L.R.B. 1404
     (2014), ruled
    that the full- and part-time non-tenure-track faculty of the
    University of Southern California’s (USC’s) Roski School of
    Art and Design exercised no effective control over university
    policies and, as non-managerial employees, were therefore
    eligible to join a union. USC petitions for review, arguing,
    among other things, that the Pacific Lutheran framework
    conflicts in several different ways with Yeshiva. Because we
    agree that one aspect of the Board’s decision here—namely, its
    extension of Pacific Lutheran’s “majority status rule” to
    faculty subgroups—conflicts with Yeshiva, we grant the
    petition in part and deny the Board’s cross-application for
    enforcement.
    I.
    Designed by Congress to quell “industrial strife” and its
    harmful effects on the “channels of commerce,” the National
    Labor Relations Act aimed to stabilize industry by vesting
    industrial workforces with new labor rights. See Pub. L.
    No. 74-198, § 1, 
    49 Stat. 449
    , 449 (1935) (codified as amended
    at 
    29 U.S.C. § 151
     et seq.). Congress sought to “redress the
    perceived imbalance of economic power between labor and
    management . . . by conferring certain affirmative rights on
    employees and by placing certain enumerated restrictions on
    the activities of employers.” American Ship Building Co. v.
    N.L.R.B., 
    380 U.S. 300
    , 316 (1965). “The central purpose of
    [the NLRA] was to protect employee self-organization and the
    process of collective bargaining from disruptive interferences
    by employers.” 
    Id. at 317
    .
    A.
    Years after Congress passed the NLRA, the Supreme
    Court issued two opinions central to the question before us in
    this case. First, in N.L.R.B. v. Bell Aerospace Co. Division of
    4
    Textron Inc., the Court held that although the NLRA, by its
    terms, covers all employees (except for supervisors and other
    exemptions immaterial to this case, see 
    29 U.S.C. § 152
    (3),
    (12)), it nonetheless excludes “managerial” employees from its
    protections. 
    416 U.S. 267
    , 283–84 (1974). As the Court
    explained, Congress “regarded [managers] as so clearly outside
    the [NLRA] that no specific exclusionary provision was
    thought necessary.” 
    Id. at 283
    .
    Second, in N.L.R.B. v. Yeshiva University, the Court
    clarified for the first time that the NLRA covers university
    employees and provided guidance about when university
    faculties constitute managerial employees exempt from the
    NLRA’s coverage. See 
    444 U.S. at
    682–90. In doing so, the
    Court distinguished between the “type of management-
    employee relations that prevail in the pyramidal hierarchies of
    private industry” and those that exist within a “typical ‘mature’
    private university” where “authority . . . is divided between a
    central administration and one or more collegial bodies”
    composed of academic faculty. 
    Id. at 680
    . Together,
    administration and faculty may manage a university through a
    system of shared governance—“‘the process by which various
    constituents (traditionally governing boards, senior
    administration, and faculty . . .) contribute to decision making
    related to college or university policy and procedure.’”
    American Council on Education’s (“ACE”) Br. 4 (alteration in
    original) (quoting Association of Governing Boards of
    Universities and Colleges, Shared Governance: Changing with
    the Times 3 (Mar. 2017)). It was respect for the “shared
    authority” that can be embedded in university governance,
    paired with the need to safeguard the protections afforded by
    the NLRA, that guided the Court in Yeshiva. See 
    444 U.S. at 680
    .
    5
    The facts of Yeshiva are straightforward. A union seeking
    to represent most of the university’s full-time faculty filed a
    representation petition, requesting that the Board certify it as
    the faculty’s bargaining agent. 
    Id.
     at 674–75. The university
    argued that the faculty were managerial, but the Board found
    otherwise. 
    Id. at 678
    . Grounding its decision in the NLRA’s
    protection of professional employees—a designation
    encompassing employees engaged in “predominantly
    intellectual” work, 
    29 U.S.C. § 152
    (12)—the Board found that
    members of Yeshiva’s faculty were professional employees
    who enjoy the NLRA’s protections, rather than exempted
    managerial ones. Yeshiva, 
    444 U.S. at 678
    .
    The Supreme Court disagreed. It pointed out that
    “professionals, like other employees, may be exempted from
    coverage . . . under the judicially implied exclusion for
    ‘managerial employees.’” 
    Id.
     at 681–82. In non-university
    settings, moreover, the Board classifies as exempted
    managerial employees those individuals who “represent[]
    management interests by taking or recommending
    discretionary actions that effectively control or implement
    employer policy.” 
    Id. at 683
    . Therefore, the Court explained,
    the same general analysis must guide the Board in the
    university setting. 
    Id. at 686
    . As relevant here, the Court
    dismissed as inconsistent with these precedents the Board’s
    arguments that faculty members were non-managerial because
    they engaged in collective decision making (true of many
    corporate managers working through boards and committees)
    and because they enjoyed less than “ultimate” authority (held
    in corporate settings by the board of directors). 
    Id.
     at 684–85,
    685 nn. 20–21.
    Instead, the Court looked to the principles underlying the
    managerial exception—namely, that managers fall outside the
    NLRA’s protections because “an employer is entitled to the
    6
    undivided loyalty of its representatives.” 
    Id. at 682
    . Unions
    divide that loyalty, and the fear of compromised loyalty was
    “particularly acute” at a university like Yeshiva, where the
    faculty exercised “pervasive[]”—even “absolute”—control
    over academic matters. 
    Id. at 679, 686, 689
    . “The controlling
    consideration in this case,” the Court explained, “is that the
    faculty of Yeshiva University exercise authority which in any
    other context unquestionably would be managerial.” 
    Id. at 686
    .
    Elaborating, the Court stated:
    [The faculty’s] authority in academic matters is
    absolute. They decide what courses will be offered,
    when they will be scheduled, and to whom they will be
    taught. They debate and determine teaching methods,
    grading policies, and matriculation standards. They
    effectively decide which students will be admitted,
    retained, and graduated. On occasion their views have
    determined the size of the student body, the tuition to
    be charged, and the location of a school. When one
    considers the function of a university, it is difficult to
    imagine decisions more managerial than these. To the
    extent the industrial analogy applies, the faculty
    determines within each school the product to be
    produced, the terms upon which it will be offered, and
    the customers who will be served.
    
    Id.
    With the Yeshiva faculty’s “absolute” academic authority
    as a backdrop, the Court explained to the Board—in language
    important to the issue before us today—how to identify
    managerial faculty in future university cases. Faculty qualify
    as managerial when they exercise “effective recommendation
    or control” over central employer policies. 
    Id.
     at 683 n.17.
    Faculty exercise such control when a university “depends on
    7
    the [faculty’s] professional judgment . . . to formulate and
    apply crucial policies constrained only by necessarily general
    institutional goals,” particularly when the university “requires
    faculty participation in governance.” 
    Id. at 689
    .
    That said, the Court took care to avoid “sweep[ing] all
    professionals outside the [NLRA] in derogation of Congress’
    expressed intent to protect them.” 
    Id. at 690
    . Faculty are
    protected by the NLRA if their “decisionmaking is limited to
    the routine discharge of professional duties in projects to which
    they have been assigned.” 
    Id.
     Further cabining its holding, the
    Court recognized that faculties are heterogeneous, and that
    non-managerial subsets may exist within a faculty entrusted
    with managerial authority. For instance, the Board might draw
    a “rational line” between “tenured and untenured faculty
    members.” 
    Id.
     at 690 n.31. Such a distinction turns on “how a
    faculty is structured and operates.” 
    Id.
     In saying this, the Court
    made clear that “this is a starting point only, and that other
    factors not present here may enter into the analysis in other
    contexts.” 
    Id.
    B.
    For several decades following Yeshiva, the Board, when
    determining a given faculty’s managerial status, applied a
    totality-of-the-circumstances approach informed by the
    contours of that case. See, e.g., American International
    College, 
    282 N.L.R.B. 189
    , 190–202 (1986) (discussing at
    length whether the faculty at issue fell “within the scope of the
    Supreme Court’s decision in [Yeshiva]”). But in LeMoyne-
    Owen College v. N.L.R.B., 
    357 F.3d 55
     (D.C. Cir. 2004), we
    found the Board’s approach inadequate. There the Board had
    classified the full-time faculty of a small private institution in
    Memphis as non-managerial. 
    Id.
     at 55–56, 60. Although the
    Board had relied on the fact that circumstances at LeMoyne-
    8
    Owen were similar to those at other colleges where it had
    classified faculty as non-managerial, we were concerned that
    the Board failed to “discuss or even mention a single one of the
    precedents on which the College relied.” 
    Id. at 60
    . Ending our
    analysis before reaching the managerial status of the college’s
    faculty, we observed that, although the Board’s totality-of-the-
    circumstances approach followed naturally from Yeshiva’s
    “long list of relevant factors” paired with “the exquisite variety
    of academic institutions across the country,” the Board must
    provide an “adequate explanation for the result it reached in
    this case.” 
    Id. at 57, 61
    . We instructed the Board to delineate
    “which factors are significant and which less so, and why” in
    managerial-faculty determinations. 
    Id. at 61
    . Doing so, we
    explained, would afford faculty, universities, and reviewing
    courts “predictability and intelligibility” concerning the
    Board’s “[application of] the test to varied fact situations.” Id.;
    see also Point Park University v. N.L.R.B., 
    457 F.3d 42
    , 50
    (D.C. Cir. 2006) (reiterating this requirement in another faculty
    case).
    The Board endeavored to satisfy LeMoyne-Owen in
    Pacific Lutheran University. Unlike Yeshiva, which involved
    full-time faculty, Pacific Lutheran concerned a faculty
    subgroup—specifically, full-time “contingent” (non-tenure
    eligible) faculty. 361 N.L.R.B. at 1417. Drawing on its “30-
    plus years applying Yeshiva” and echoing the Supreme Court’s
    language, the Board used Pacific Lutheran as a platform to
    launch a new test designed “to answer the question whether
    faculty in a university setting actually or effectively exercise
    control over decision making pertaining to central policies of
    the university such that they are aligned with management.” Id.
    Under the Pacific Lutheran framework for determining
    whether faculty qualify as managerial, the Board “organize[s]
    [its] review of faculty decision-making into five general areas”:
    9
    academic programs, enrollment management policies,
    finances, academic policies, and personnel policies and
    decisions. Id. The Board classifies the first three as “primary”
    and the last two as “secondary.” Id. at 1420. Although faculty
    participation in these areas takes various forms, under the
    Pacific Lutheran framework the Board trains its focus on
    participation through service on university committees, which
    specialize in a given field and then propose policies to the full
    faculty or to the university’s administration. See id. at 1424–28
    (consistently analyzing faculty participation by looking to
    faculty committees).
    Again echoing Yeshiva, the Board then considers whether
    the faculty exercise “actual control or effective
    recommendation” authority over each of these five areas. Id.
    at 1421. The test for “effective” control is demanding:
    “recommendations must almost always be followed by the
    administration. Further, faculty recommendations are
    ‘effective’ if they routinely become operative without
    independent review by the administration.” Id. (internal
    citation omitted). Intent on ensuring that faculty exercise
    “actual—rather than mere paper—authority,” Pacific Lutheran
    requires “specific evidence” of the process by which the
    administration adopts faculty recommendations. Id. Under
    Pacific Lutheran, the Board looks at “both the structure of
    university decisionmaking and where the faculty at issue fit
    within that structure, including the nature of the employment
    relationship.” Id. at 1421–22. Relevant distinctions include
    “tenured vs. tenure eligible vs. nontenure eligible” and “regular
    vs. contingent” faculty members. Id. at 1422. Rather than
    requiring that managerial faculty control some set number of
    decision-making areas, Pacific Lutheran calls for a holistic
    review of the control exerted over the five areas. See id. at 1423
    (noting that to determine managerial status the Board will
    assess faculty’s control “over those areas”).
    10
    Beyond these context-specific inquiries, and central to this
    case, Pacific Lutheran sets a bright-line “majority status rule”
    under which a committee’s actual control or effective
    recommendation authority over a particular decision-making
    area may be ascribed to faculty only if they constitute a
    majority of that committee: “[i]f faculty members do not exert
    majority control, we will not attribute the committee’s conduct
    to the faculty.” Id. at 1421 n.36.
    Applying this framework to the situation at Pacific
    Lutheran, the Board determined that the contingent faculty
    were non-managerial. Although the university had recently
    allowed contingent faculty to sit on committees, no such
    faculty members had yet joined a committee and, in any event,
    it appeared that they would have had no “right to vote within
    their respective divisions, schools, or constituent departments.”
    Id. at 1424, 1427–28. Contingent faculty did participate in and
    have a vote at the faculty assembly, but the Board characterized
    the assembly as “little more than a conduit to transmit
    previously      agreed-upon      recommendations        to    the
    administration” and observed that contingent faculty
    comprised only about twenty percent of the faculty assembly’s
    average attendees. Id. at 1428. According to the Board, the
    nature of the contingent faculty members’ employment
    relationship with the university also counseled against a finding
    of managerial status. In contrast to Yeshiva, where the
    university “require[d] faculty participation in governance,” 
    444 U.S. at 689
    , the Pacific Lutheran administration rarely
    discussed with contingent faculty its expectations for their
    university service, such as committee participation, see Pacific
    Lutheran, 361 N.L.R.B. at 1423. Contingent faculty had to
    renew their contracts annually and received minimal
    institutional support (such as funding for professional
    development or research). Id.
    11
    In considering whether faculty held a majority of
    committee seats, the Board left uncertain whether the majority
    status rule applied to the contingent faculty only or to the
    faculty as a whole. Even if contingent faculty members sat on
    committees, the Board observed, “they would be a minority on
    the . . . committee[s] as their membership is currently
    structured.” Id. at 1428. Because the faculty as a whole
    constituted a minority on all of these committees, id. at 1424,
    however, the significance of this observation was unclear.
    Two Board members—Phillip Miscimarra and Harry
    Johnson—separately dissented in part. They “generally
    agree[d]” with the Board’s “admirable effort” to craft distinct,
    workable decision-making areas. Id. at 1430 (Miscimarra,
    Member, concurring in part and dissenting in part), 1441
    (Johnson, Member, dissenting). Uncertain about how the
    Board would weigh the “primary” and “secondary” areas in
    future cases, however, the dissenters believed that “substantial”
    authority in secondary areas—unaccompanied by effective
    control over any of the three primary areas—may sometimes
    be sufficient to trigger managerial status. Id. at 1429–30
    (Miscimarra, Member, concurring in part and dissenting in
    part); see also id. at 1441–42 (Johnson, Member, dissenting).
    The dissenters focused primarily on Pacific Lutheran’s
    “treatment      of    authority,    control,   and     effective
    recommendation” authority, which they considered “too
    onerous and inflexible.” Id. at 1430 (Miscimarra, Member,
    concurring in part and dissenting in part). According to the
    dissenters, the Pacific Lutheran framework demands too much
    because it requires that the administration “almost always”
    follow faculty recommendations. Id. at 1430 (Miscimarra,
    Member, concurring in part and dissenting in part), 1443
    (Johnson, Member, dissenting). “[B]y failing to consider the
    actual, diverse processes of university business operations and
    12
    governance,” Johnson argued, Pacific Lutheran “raised the bar
    for establishing managerial status of faculty to an unattainable
    height.” Id. at 1442–43. He also believed that the Board had
    fashioned “a false dichotomy” when it held that committees
    exercise effective control only if administrators routinely
    accept the committees’ recommendations and do so without
    independent review. Id. at 1443–44. Such a rule, he contended,
    flouts the ideal of universities as “places rich in dialogue”
    between the administration and faculty. Id. at 1444.
    C.
    The University of Southern California, a large private
    university in Los Angeles, has twenty-two schools, some 6,600
    faculty, and between 30,000 and 40,000 students. One of these
    schools, the Gayle Garner Roski School of Art and Design
    (“Roski”)—the venue for the dispute before us—offers
    undergraduate and graduate degrees in fine arts and critical
    studies, among others. See University of Southern California
    (“USC”), 365 N.L.R.B. No. 11, at *7 (Dec. 30, 2016). In 2015,
    the Service Employees International Union, Local 721
    (“Union”) petitioned to represent Roski’s full- and part-time
    non-tenure-track faculty. Id. at *5.
    Reprising the battle lines drawn in Yeshiva, USC
    contended that the Roski non-tenure-track faculty were
    managerial, and the Union disagreed. In a decision adopted by
    the Board without opinion, the Regional Director, applying the
    Pacific Lutheran framework, found the Roski non-tenure-track
    faculty non-managerial. See id. at *1, *18.
    The Regional Director began by addressing several issues
    left unresolved in Pacific Lutheran. She first confirmed what
    the Board had hinted in that case: to exercise effective control
    over a committee, the faculty subgroup seeking recognition—
    not just the faculty as a whole—must hold a majority of
    13
    committee seats. “[E]ven if the faculty on [either committee]
    could be said to actually or effectively control decisionmaking
    . . . , I would not attribute that control to the nontenure track
    faculty at issue here, as they do not constitute a majority of
    either committee.” Id. at *16. Second, although Pacific
    Lutheran left ambiguous whether, for a committee to exercise
    effective control, the administration must “almost always”
    accept a committee’s recommendations and those
    recommendations must “routinely become operative without
    independent review,” Pacific Lutheran, 361 N.L.R.B. at 1421,
    or whether just one or the other would do, the Regional
    Director indisputably required both: “The Board also clarified
    that for faculty recommendations to be ‘effective,’ the
    administration      must      ‘almost    always’     adopt    the
    recommendations, and do so ‘routinely’ without independent
    review.” USC, 365 N.L.R.B. at *15. Third, the Regional
    Director determined that exercising effective control over one
    secondary area “alone” is insufficient to trigger faculty
    managerial status. Id. at *17. By affirming the Regional
    Director’s decision, the Board has, in effect, adopted these
    interpretations as its own. See id. at *1 n.1 (“The Regional
    Director’s decision properly applied [Pacific Lutheran].”).
    Applying this interpretation of Pacific Lutheran, the
    Regional Director classified the Roski non-tenure-track faculty
    as non-managerial. For purposes of determining effective
    control, the Regional Director centered her discussion around
    a dozen or so university-wide committees and other USC
    faculty bodies, including the Roski school-level faculty
    council, that USC contends provide faculty with opportunities
    to weigh in on university governance. Id. at *15–18. The
    committees conduct studies, write reports, and make
    recommendations to either the Academic Senate or the provost.
    Id. at *8. The University Committee on Curriculum, for
    instance, approves, rejects, or modifies every proposed USC
    14
    course, program, major, minor, and degree offering. Id. at *9,
    *15. Although the Committee on Finance and Enrollment has
    made only a few recommendations, those recommendations
    have involved significant issues, including the creation of a
    university-wide plan to address graduate student enrollment,
    whether to maintain a holistic review process for undergraduate
    student admissions, and the payout rate of USC’s endowment.
    Id. at *10, *16–17. Other committees make recommendations
    on academic programs, teaching guidelines, software upgrades,
    grading policies, appointments, promotions, and tenure
    decisions. Id. at *8–13.
    Most USC university-wide and school-specific
    committees are open to all faculty members, including non-
    tenure track, though non-tenure-track faculty are excluded
    from decisions concerning tenure. Id. at *11. Committees are
    almost 100 percent faculty, although some faculty also have
    administrative appointments. Administrators occasionally sit
    “ex officio” on committees where they have no vote. See id.
    at *8–13.
    Looking at all committees relevant to each of the five
    decision-making areas, the Regional Director determined that
    USC had failed to show that the faculty serving on these
    committees exercised effective control over any decision-
    making area. Id. at *18; see also Pacific Lutheran, 361
    N.L.R.B. at 1427 n.65 (noting that the party asserting
    managerial status assumes the burden of proof). In support, she
    found that USC had failed to provide “specific evidence,” as
    required by Pacific Lutheran, 361 N.L.R.B. at 1421, of the type
    of review the administration conducted of the committees’
    recommendations before accepting them. See USC, 365
    N.L.R.B. at *15–18. She also found that the testimony
    concerning the work of some committees was vague, see id. at
    *15, 17–18, as was the testimony about the decision-making
    15
    authority of other committees, see id. For still other
    committees, she found that they had offered too few
    recommendations to characterize their recommendations as
    “routinely” followed. See id. at *16.
    In further support of her conclusion that the Roski non-
    tenure-track faculty exercised no effective control, the
    Regional Director found that the nature of their “tenuous
    employment” relationship “limit[s]” their role at the university.
    Id. at *18. Though non-tenure-track faculty are eligible to join
    any committee and make up about three-fourths of the USC
    faculty, they represent a minority on almost every committee.
    Id. at *7–9. They receive little to no institutional support in the
    form of funding, evaluations, or other career guidance; “[i]n
    fact, [non-tenure-track faculty witnesses] testified that
    administrators in their departments or schools have never met
    with them to discuss expectations about their teaching, their
    scholarship or artistic work, or their service to the University.”
    Id. at *8.
    Following her discussion of most every committee
    (including all committees in the three primary areas), the
    Regional Director also found that, even if the relevant
    committees exercised effective control, “nontenure track
    faculty do not constitute a majority of [those] committee[s].”
    Id. at *17. Therefore, “they cannot be found to possess any
    managerial control.” Id.
    Upon finding both that no committee exercised effective
    control and that the Roski non-tenure-track faculty held a
    minority of seats on the key committees, the Regional Director
    concluded that USC had “failed to establish that the full-time
    and/or part-time nontenure track faculty at . . . the Roski School
    actually or effectively exercise control over decision making
    pertaining to central policies of the university.” Id. at *18. As
    16
    noted, on a request for review, the Board adopted the Regional
    Director’s opinion in full. Id. at *1 & n.1.
    Member Miscimarra, one of the Pacific Lutheran
    dissenters, again disagreed. Asserting that the Board holds
    managers in other industries to a lower standard, Miscimarra
    faulted the Board for ascribing managerial status to only those
    faculty with “unreviewable authority.” Id. at *2 (Miscimarra,
    Member, dissenting). He also believed that the Court in
    Yeshiva had rejected the idea that possessing a majority of
    committee seats was a prerequisite for exercising effective
    control over a committee. He put it this way:
    [Yeshiva] held that a faculty member may possess
    managerial authority even though he or she cannot
    individually establish policy separate from the
    committees on which he or she serves. Similarly,
    faculty members in an individual department or
    program may be managerial, even if as a group they
    are a minority of the total faculty and are outnumbered
    and outvoted on every issue.
    Id. at *3–4. In Miscimarra’s view, extension of the majority
    status rule to determine the managerial status of a faculty
    subgroup conflicts with “the principle of collegial managerial
    authority that the Supreme Court recognized in Yeshiva.” Id.
    at 3.
    Following the Regional Director’s decision and the
    Board’s adoption of it, the Roski non-tenure-track faculty
    voted to form a bargaining unit represented by the Union.
    When USC refused to bargain—an unfair labor practice under
    the NLRA, see 
    29 U.S.C. § 158
    (a)(5)—the Union filed a
    complaint with the Board. USC acknowledged its refusal to
    bargain, and challenged the certification on the grounds that
    Pacific Lutheran conflicts with Yeshiva and that the Roski non-
    17
    tenure-track faculty in fact exercise managerial authority. The
    Board granted summary judgment to the Union. See University
    of Southern California, 365 N.L.R.B. No. 89, at *1 (June 7,
    2017).
    In its petition for review, USC makes three basic
    arguments. First, it argues that several elements of the Pacific
    Lutheran framework, as applied in this case, conflict with
    Yeshiva: its requirement that a faculty subgroup must hold a
    majority of committee seats in order to exercise effective
    control through a committee, its standard for “effective”
    control, and its classification of the five decision-making areas
    as primary or secondary. Whether the Pacific Lutheran
    framework comports with Yeshiva is an issue of first
    impression given that the university in Pacific Lutheran never
    petitioned for review and that no other circuit has yet
    considered the question. Second, USC argues that, contrary to
    LeMoyne-Owen, the Pacific Lutheran framework fails to
    provide a workable standard to determine the managerial status
    of faculty. And third, even assuming the validity of the Pacific
    Lutheran framework, USC argues that the Regional Director
    lacked substantial evidence to classify the Roski non-tenure-
    track faculty as non-managerial.
    In considering USC’s challenges, we defer to the Board’s
    judgment, born of its expertise, so long as its decision is
    “consistent with controlling precedent,” based on “substantial
    evidence,” and neither “arbitrary” nor “capricious.”
    International Union of Operating Engineers, Local 147 v.
    N.L.R.B., 
    294 F.3d 186
    , 188 (D.C. Cir. 2002); see also 
    5 U.S.C. § 706
    (2)(A); N.L.R.B. v. Curtin Matheson Scientific, Inc., 
    494 U.S. 775
    , 786 (1990) (explaining that because “the NLRB has
    the primary responsibility for developing and applying national
    labor policy,” courts will uphold any rule that is “rational and
    consistent with the [NLRA], even if we would have formulated
    18
    a different rule had we sat on the Board” (internal citation
    omitted)).
    II.
    We begin with USC’s argument that the Pacific Lutheran
    framework—and consequently, the decision at issue here—is
    “[in]consistent with controlling precedent,” i.e., that it conflicts
    with the Supreme Court’s decision in Yeshiva. But as even its
    dissenters acknowledge, Pacific Lutheran represents an
    “admirable effort” by the Board to tame a thicket of case law
    that touches on numerous interrelated features of the faculty
    experience at universities. Pacific Lutheran, 361 N.L.R.B. at
    1441 (Johnson, Member, dissenting). And for the most part,
    that effort succeeds. There is, however, a major problem.
    Under Pacific Lutheran, as interpreted by the Board in this
    case, a faculty subgroup seeking recognition exercises effective
    control over a decision-making area through its participation
    on a committee only when that subgroup constitutes a majority
    of the committee. See Pacific Lutheran, 361 N.L.R.B. at 1421
    n.36; USC, 365 N.L.R.B. at *16. This rule, which we shall refer
    to as the “subgroup majority status rule,” is critical because, as
    discussed above, see supra at 9, the Board generally looks to a
    faculty’s authority at the committee level when determining
    whether the faculty exercise effective control over Pacific
    Lutheran’s five decision-making areas.
    USC first claims that the subgroup majority status rule
    resurrects the theory, foreclosed by Yeshiva, that faculty can
    attain managerial status based only on authority wielded
    individually, as opposed to authority shared collectively with
    others. See Yeshiva, 
    444 U.S. at
    685 & n.21 (criticizing the
    theory as “flatly inconsistent” with Board precedents that credit
    managerial authority to “supervisors who work through
    committees”). But in neither Pacific Lutheran nor here did the
    19
    Board run afoul of that precise holding. Indeed, the Board
    agrees that faculty can exercise managerial authority
    collectively. See Respondent’s Br. 37 (“Faculty who constitute
    the majority of a committee can be managerial based on their
    service on that committee, even though the authority they
    exercise there is collective.”). The extension of Pacific
    Lutheran’s majority status rule to faculty subgroups instead
    reflects the Board’s belief that a subgroup, acting collectively,
    is unable to exercise managerial authority through a committee
    when that subgroup holds a minority of committee seats.
    Assuming that understanding of the Board’s subgroup
    majority status rule, USC next argues that the rule “simply
    disregard[s]” the contributions that minority subgroups can
    make to university governance. Petitioner’s Br. 34. Under the
    majority status theory, USC continues, even when a university
    draws “no distinction” between faculty subgroups “in their
    roles in faculty governance,” including situations where the
    subgroups “all participate in the effective management of the
    University,” the Board will “arbitrarily say that one category
    must be in the majority[,] . . . necessarily . . . render[ing] the
    other category non-managerial—when in fact, all are
    managerial.” Id. at 38 (emphases omitted). Because a
    subgroup’s “ability to invoke the rights or protections of the
    [NLRA] should not hinge on whether some other group of
    faculty control or effectively recommend university policy,”
    the Board’s response goes, it would be inappropriate to deny a
    subgroup the NLRA’s protections when an entirely different
    group of faculty, concerned about advancing its own priorities
    rather than the subgroup’s, runs the show. Respondent’s Br. 35
    (emphasis in original).
    In our view, the Board’s subgroup majority status rule
    rests on a fundamental misunderstanding of Yeshiva. To
    20
    explain why, we return to the Court’s opinion and specifically
    to three key themes.
    First, as noted above, the Court drew a sharp distinction
    between the “pyramidal” hierarchies characteristic of private
    industry and the faculty “bodies” at universities. Yeshiva, 
    444 U.S. at 680
    . “[T]he authority structure of a university does not,”
    the Court explained, “fit neatly within the statutory scheme we
    are asked to interpret,” and for that reason, “the Board has
    recognized that principles developed for use in the industrial
    setting cannot be ‘imposed blindly on the academic world.’”
    
    Id.
     at 680–81 (quoting Syracuse University, 
    204 N.L.R.B. 641
    ,
    643 (1973)). In the “pyramidal” industrial arena, the Board
    looks to whether individuals, or groups of individuals, exercise
    managerial authority. Id. at 680. By contrast, the Court in
    Yeshiva returned time and again to the question of whether the
    “faculty” as a body—as opposed to individual professors or
    subgroups—exercises managerial authority. To the Court, the
    “controlling consideration” was that the “faculty at Yeshiva
    University exercise authority which in any other context
    unquestionably would be managerial.” Id. at 686 (emphasis
    added). “The ‘business’ of a university is education,” the Court
    explained, “and its vitality ultimately must depend on academic
    policies that largely are formulated and generally are
    implemented by faculty governance decisions.” Id. at 688
    (emphasis added). Continuing its focus on the “faculty” as a
    body, the Court observed that “[t]he university requires faculty
    participation in governance”; that “Yeshiva and like
    universities must rely on their faculties to participate in the
    making and implementation of their policies”; and that “[t]he
    faculty participate in University-wide governance through their
    representatives on an elected student-faculty advisory council.”
    Id. at 675–76, 689 (emphasis added).
    21
    These repeated references to the “faculty” as a body are
    not linguistic accidents; they are central to the Court’s
    reasoning. Take the Court’s discussion of the bedrock principle
    underlying the managerial exception: that employers deserve
    the loyalty of employees who exercise discretionary authority
    over central employer policies. Id. at 687–88. Highlighting that
    the faculty functions as a single body, the Court observed that
    if, consistent with principles of shared governance, the
    university “depends on the professional judgment of its faculty
    to formulate and apply crucial policies,” then the university
    deserves those employees’ “undivided loyalty,” which in turn
    triggers managerial status. Id. at 682, 689 (emphasis added).
    The Court’s analysis turned not on an aggregation of the power
    delegated to a series of individuals or a mosaic of subgroups—
    the focus of the Board’s subgroup majority status rule—but
    rather on the role played by the faculty as a body.
    Reinforcing this idea—and this is Yeshiva’s second
    theme—the Court repeatedly stressed the importance of
    collegiality. “[A]uthority in the typical ‘mature’ private
    university,” the Court explained, is split between the
    administration and “one or more collegial bodies.” Id. at 680.
    The Court observed that “[t]he Board itself has noted that the
    concept of collegiality ‘does not square with the traditional
    authority structures with which th[e] [NLRA] was designed to
    cope,’” and that “traditions of collegiality continue to play a
    significant role at many universities.” Id. (second alteration in
    original) (quoting Adelphi University, 
    195 N.L.R.B. 639
    , 648
    (1972)).
    The Board’s subgroup majority status rule is unfaithful to
    this critical aspect of Yeshiva. It ignores the possibility that
    faculty subgroups, despite holding different status within the
    university, may share common interests and therefore
    effectively participate together as a body on some or all of the
    22
    issues relevant to managerial status. It is entirely plausible that,
    for example, non-tenure-track faculty, especially full-time non-
    tenure-track faculty, would agree with tenure-track faculty on
    questions of course offerings, academic integrity, and grading
    policies. Yet the Board’s subgroup majority status rule
    presupposes that non-tenure-track faculty have no authority
    over such matters unless they constitute a majority of the
    relevant committee. Of course, the interests of some minority
    faculty subgroups may differ from the majority on certain
    issues, such as with respect to promotion and salary. That,
    however, is precisely where the concept of collegiality comes
    into play. Disregarding this fundamental characteristic of
    university governance, the Board’s subgroup majority status
    rule assumes that minority subgroups can never work out their
    differences with the majority.
    Taken together, these two themes of Yeshiva—a focus on
    the faculty as a body and an emphasis on collegiality—
    demonstrate that the question the Board must ask is not whether
    a particular subgroup can force policies through based on crude
    headcounts, but rather whether that subgroup is structurally
    included within a collegial faculty body to which the university
    has delegated managerial authority. This reading finds support
    in Yeshiva’s third theme: the Court’s guidance on how the
    Board should approach situations where the faculty members
    seeking recognition constitute a subgroup, such as in this case
    (non-tenure-track) and in Pacific Lutheran (contingent).
    Employees, the Court explained, may not be considered
    management and thus excluded from the NLRA’s coverage if
    their “decisionmaking is limited to the routine discharge of
    professional duties in projects to which they have been
    assigned.” Yeshiva, 
    444 U.S. at 690
    . Indeed, the Court noted
    that there may have been “faculty members at Yeshiva” itself
    “who properly could be included in a bargaining unit.” 
    Id.
     at
    690 n.31. For example, “a rational line could be drawn between
    23
    tenured and untenured faculty members, depending upon how
    a faculty is structured and operates.” 
    Id.
     Put another way, the
    question the Board must ask is not a numerical one—does the
    subgroup seeking recognition comprise a majority of a
    committee—but rather a broader, structural one: has the
    university included the subgroup in a faculty body vested with
    managerial responsibilities? To answer this question, the Board
    must, as required by Yeshiva, examine how the faculty is
    “structured” and “operates,” as well as the duties employees
    have been “assigned.” For example, as in Yeshiva, does the
    university “require” faculty members to participate in
    committees? If this analysis demonstrates that the subgroup
    seeking recognition is structurally part of a faculty body to
    which the university has delegated managerial authority, then,
    apart from several exceptions we shall discuss below, that ends
    the matter: the subgroup is managerial regardless of whether its
    members constitute a majority of the relevant committees or
    whether they even participate at all.
    Two additional considerations support this understanding
    of Yeshiva.
    First, the Court relied on a line of Board decisions from the
    private sector holding that it is possible for minority employee
    shareholders “who owned enough stock to give them, as a
    group, a substantial voice in the employer’s affairs” to exercise
    effective control, even absent majority control. Yeshiva, 
    444 U.S. at
    685 n.21. Indeed, the Board itself has recognized that it
    “has excluded groups of shareholder-employees from
    bargaining units even though they collectively owned less than
    half of the employers’ stock.” Upper Great Lakes Pilots, Inc.,
    
    311 N.L.R.B. 131
    , 132 n.9 (1993). Although the Board cites
    these cases in its brief while discussing this very issue, it fails
    to acknowledge their inconsistency with its subgroup majority
    status rule.
    24
    Second, and quite apart from Yeshiva, we just cannot see
    how the subgroup majority status rule will work. As USC
    notes, “the make-up of a particular committee will necessarily
    change from year to year. If only the majority category is
    managerial, then from one year to the next, different categories
    of perfectly managerial faculty could be deemed non-
    managerial for no other reason than a one- or two-person swing
    on a committee roster.” Petitioner’s Br. 38. In his dissent,
    Member Miscimarra pointed out that, under the subgroup
    majority status rule, slicing and dicing the faculty in different
    ways—by tenure status, school, seniority, etc.—may allow
    “even faculty who indisputably exercise managerial authority”
    to qualify as non-managerial. USC, 365 N.L.R.B. at *4 & n.7
    (Miscimarra, Member, dissenting). In its amicus brief, the
    American Council on Education likewise warns that “any
    group of faculty can be sub-divided until it no longer
    commands a majority.” ACE Br. 27. The subgroup majority
    status rule contributes to this strategic division of faculties;
    Yeshiva’s structural approach avoids it.
    That said, whether an individual subgroup possesses a
    majority of committee seats is not always irrelevant. Quite to
    the contrary, determining whether a subgroup holds a decisive
    bloc of committee seats may be necessary where a subgroup’s
    interests fundamentally diverge from those of the majority.
    Although the Court in Yeshiva emphasized the value of faculty
    collegiality, there may well be issues on which the interests of
    the subgroup and the faculty as a whole differ so significantly
    that they cannot be reconciled even through collegial
    compromise. Under such circumstances, which the Board can
    identify only through a careful analysis of how the faculty
    seeking recognition actually functions, the Board might
    appropriately conclude that the subgroup cannot exercise
    effective control unless it constitutes a majority of the relevant
    committees. Likewise, if a subgroup that the university expects
    25
    to participate in a committee nonetheless fails to do so, this may
    signal the presence of structural barriers to that group’s
    participation. In this case, for example, the Board may well be
    correct that there is something about the status of non-tenure-
    track faculty, especially part-time non-tenure-track, that
    effectively silences any managerial “voice,” Pacific Lutheran,
    361 N.L.R.B. at 1423, that such faculty otherwise might
    possess. See Yeshiva, 
    444 U.S. at
    690 n.31 (acknowledging that
    “other factors not present here,” such as tenure status, “may
    enter into the analysis in other contexts”).
    To be sure, the Pacific Lutheran framework accounts for
    these factors (diverging interests and the nature of non-tenure-
    track employment). See 361 N.L.R.B. at 1421–22 (looking at
    the “nature of the employment relationship,” including
    “tenured vs. tenure eligible vs. nontenure eligible”). But
    Pacific Lutheran, as interpreted by the Board in this case, runs
    afoul of Yeshiva by using these factors as part of a
    determination focused on whether the petitioning subgroup
    alone exercises effective control. The Board should instead, as
    required by Yeshiva, think of this analysis as having two
    distinct inquiries: whether a faculty body exercises effective
    control and, if so, whether, based on the faculty’s structure and
    operations, the petitioning subgroup is included in that
    managerial faculty body. Only as part of the latter analysis
    should the Board dig into whether a subgroup’s actual interests
    diverge so substantially from those championed by the rest of
    the faculty that holding a minority of seats on the relevant
    committees is akin to having no managerial role at all, or
    whether a subgroup’s low participation rates stem from a
    tenuous employment relationship that vitiates any managerial
    role the university expects the subgroup to perform. See
    Yeshiva, 
    444 U.S. at
    674–77, 686 (examining closely the
    specific operations at Yeshiva).
    26
    Of course, the Board has flexibility over how to organize
    its analysis in any given case. In some situations, it might make
    sense to address these two inquiries sequentially: is there a
    managerial faculty body and, if so, is the petitioning subgroup
    a part of it? But in other situations, it may be unnecessary for
    the Board to consider whether a managerial faculty body exists
    because, even assuming one did, the petitioning subgroup is so
    clearly not included in it—because, for example, university
    rules prohibit its participation in committees. The critical point
    is this: however the Board proceeds, it must treat these two
    inquiries separately and may not conflate them by asking
    whether the petitioning subgroup alone exercises effective
    control.
    A final observation: in Pacific Lutheran, the Board
    emphasized that since the Court decided Yeshiva some four
    decades ago, universities “are increasingly run by
    administrators” and rely more and more on non-tenure-track
    faculty “who, unlike traditional faculty, have been appointed
    with no prospect of tenure and often no guarantee of
    employment.” Pacific Lutheran, 361 N.L.R.B. at 1422.
    According to the Board, these trends “ha[ve] the effect of
    concentrating and centering authority away from the faculty.”
    Id. Building on this point, amicus American Association of
    University Professors points out that “[r]ather than relying on
    faculty expertise and recommendations, the growing ranks of
    administrators increasingly make unilateral decisions on
    university policies and programs, often influenced by
    considerations of external market forces and revenue
    generation.” American Association of University Professors’
    Br. 10. By contrast, the American Council on Education,
    though acknowledging these trends, emphasizes “the continued
    primacy of shared governance.” ACE Br. 13. This is an
    interesting debate, and it may even be relevant. Regardless of
    national trends, however, the Board must not lose sight of the
    27
    fact that the question before it in any case in which a faculty
    subgroup seeks recognition is whether that university has
    delegated managerial authority to a faculty body and, if so,
    whether the petitioning faculty subgroup is a part of that body.
    As we explained in Point Park, this requires “an exacting
    analysis of the particular institution and faculty at issue.” 457
    F.3d at 48 (emphasis added).
    Having thus concluded that the Board’s subgroup majority
    status rule runs afoul of Yeshiva, we turn to USC’s challenge
    to Pacific Lutheran’s standard for “effective” control.
    III.
    Recall that Pacific Lutheran announced the following
    standard for determining when faculty exercise effective
    control over decision making: “[T]o be ‘effective,’
    recommendations must almost always be followed by the
    administration. Further, faculty recommendations are
    ‘effective’ if they routinely become operative without
    independent review by the administration.” 361 N.L.R.B. at
    1421 (internal citations and footnote omitted). Filling a gap left
    by the Board in Pacific Lutheran, the Regional Director
    required that both elements—“almost always” followed and
    “routinely” adopted “without independent review”—must be
    satisfied to support an effective control finding. USC, 365
    N.L.R.B. at *15. USC does not challenge the Regional
    Director’s conjunctive interpretation. Instead, drawing from
    the Pacific Lutheran dissents, the university argues that “there
    is no . . . logical conclusion” other than that the Pacific
    Lutheran standard, as interpreted in USC, resurrects the
    “ultimate authority” requirement for managerial status that
    Yeshiva forbids. Petitioner’s Br. 33 (emphasis omitted); see
    also Yeshiva, 
    444 U.S. at
    685 & nn.20–21.
    28
    In Yeshiva, the Court held that, in order to qualify as
    managerial, faculty must exercise “effective recommendation
    or control” over central university policies. Yeshiva, 
    444 U.S. at
    683 n.17. The Yeshiva faculty met that standard, the Court
    found, because their control was “substantial[] and
    pervasive[]”: among other things, the faculty “decide[d] [what]
    students will be admitted, retained, and graduated,” “decide[d]
    what courses will be offered,” and “determine[d] teaching
    methods, grading policies, and matriculation standards.” 
    Id. at 679, 686
    . The Court also explained that faculty need not have
    “final authority” in order to enjoy managerial status; a “rarely
    exercised veto power” held by the administration “does not
    diminish the faculty’s effective power.” Id at 683 n.17, 685.
    We see nothing in the Board’s two-part standard for
    “effective” control that runs afoul of Yeshiva. Although USC
    argues otherwise, the Board’s standard does not require
    “ultimate authority.” Quite to the contrary, its use of the phrase
    “almost always” allows for occasional, or as the Court put it,
    “rarely exercised,” vetoes. The word “routine” likewise leaves
    room for some administrative review. True, the standard is
    demanding, but it comports with Yeshiva, and we agree with
    the Board that setting a high bar for effective control is
    necessary to avoid interpreting the managerial exception so
    broadly that it chips away at the NLRA’s protections. See
    Pacific Lutheran, 361 N.L.R.B. at 1419 n.32 (“[W]e are
    mindful of the fundamental principle that ‘exemptions from
    [the NLRA’s] coverage are not so expansively interpreted as to
    deny protection to workers the [NLRA] was designed to
    reach.’” (quoting Holly Farms Corp. v. N.L.R.B., 
    517 U.S. 392
    ,
    399 (1996))). That said, the Board must be careful to apply its
    effective control standard with sensitivity to the notion of
    “collegial managerial authority that the Supreme Court
    recognized in Yeshiva.” USC, 365 N.L.R.B. at *3 (Miscimarra,
    Member, dissenting). “[T]raditions of collegiality continue to
    29
    play a significant role at many universities,” Yeshiva, 
    444 U.S. at 680
    , and the Board’s test for effective control must
    accommodate these traditions.
    USC complains about a stray sentence in the Regional
    Director’s opinion: “I am not convinced by the conclusory
    evidence in the record that the Board of Trustees, for example,
    would sign off without second thought on a tuition amount or
    endowment payout based solely on the recommendation of a
    newly-formed faculty committee that had never before
    considered such issues.” USC, 365 N.L.R.B. at *17 (emphasis
    added). According to USC, requiring that the administration
    accept committee recommendations “without second thought”
    sets an even higher bar for effective control than the one we
    understand the Board to have established. Petitioner’s Br. 22.
    Were this characterization of the Regional Director’s decision
    accurate, we would share USC’s concerns. The Regional
    Director, however, never suggested that her “without second
    thought” statement amounted to a new requirement for
    establishing effective control. Instead, she made the statement
    in response to USC’s contention that the administration had in
    fact accepted the newly formed Committee on Finance and
    Enrollment’s recommendations on important financial matters
    “without second thought.”
    IV.
    We can quickly dispose of USC’s remaining arguments.
    First, regarding Pacific Lutheran’s classification of the
    five decision-making areas as primary and secondary, USC
    acknowledges that Yeshiva affords the Board leeway to design
    these categories, but nonetheless argues that the Pacific
    Lutheran framework inappropriately relegates academic and
    personnel policies to secondary status while elevating finances
    to primary status. Justifying the classification, the Board
    30
    explained that the primary areas, more so than the secondary
    ones, touch the university as a whole, align faculty with
    management, and affect the “product” the university offers—
    all considerations taken from the Court’s discussion in Yeshiva.
    Pacific Lutheran, 361 N.L.R.B. at 1420; see also Yeshiva, 
    444 U.S. at
    675–77, 686, 690. Although we can imagine different
    groupings of these factors, nothing in Yeshiva dictates the
    outcome one way or the other, and the Board’s categorization
    falls well within its discretion under the NLRA. Indeed, this is
    precisely the type of line-drawing that the Board is “entitled”
    to make “without our constant second-guessing.” N.L.R.B. v.
    Kentucky River Community Care, Inc., 
    532 U.S. 706
    , 720
    (2001).
    USC next argues that, by leaving open exactly how many
    of the five decision-making areas over which faculty must
    exercise control in order to qualify as managerial, Pacific
    Lutheran fails to satisfy this court’s instruction in LeMoyne-
    Owen that it identify “which factors are significant and which
    less so, and why.” 
    357 F.3d at 61
    . We disagree. At the time of
    LeMoyne-Owen, the Board was engaging in a totality-of-the-
    circumstances analysis that we feared might be nothing more
    than “a cloak for agency whim.” 
    Id.
     In response, the Board
    developed the Pacific Lutheran framework, which provides
    detailed standards for effective control, five precisely
    articulated decision-making areas, a list of the relevant factors
    within each area, and a prioritization of the areas. True, the
    Board could have been more precise, but nothing in LeMoyne-
    Owen requires it to have done so, especially because
    managerial status determinations “do[] not lend [themselves]
    to ex ante line drawing or a mathematical exercise in box
    checking.” Respondent’s Br. 39.
    Finally, USC argues that, even if the Pacific Lutheran
    framework complies with Yeshiva, the Board’s classification of
    31
    the Roski non-tenure-track faculty as non-managerial was
    unsupported by substantial evidence. Relatedly, USC argues
    that the Regional Director erred in denying its motion to reopen
    the record concerning allegedly contradictory testimony from
    a Union witness. But given our conclusion that the Board’s
    subgroup majority status rule runs afoul of Yeshiva, and
    because we are uncertain whether the Board would have
    reached the same conclusion absent that rule, we think it best
    to leave these arguments unaddressed and to instead give the
    Board an opportunity to reconsider the case afresh under the
    proper legal standard. See Braniff Airways, Inc. v. Civil
    Aeronautics Board, 
    379 F.2d 453
    , 466 (D.C. Cir. 1967)
    (remanding to the agency because the “court [wa]s in
    substantial doubt whether the administrative agency would
    have made the same ultimate finding with the erroneous
    findings or inferences removed from the picture” (internal
    quotation marks omitted)).
    V.
    For the foregoing reasons, the petition for review is
    granted in part, the Board’s cross-application for enforcement
    is denied, and the case is remanded to the Board for further
    proceedings consistent with this opinion. We, of course,
    express no opinion as to whether the application of the differing
    standard on remand would lead to the same or a different result.
    So ordered.
