    DIANA GRIBBON MOTZ, Circuit Judge:
    Alfredo Rolando Prieto appeals the district court’s denial
    of his petition for a writ of habeas corpus pursuant to 
    28 U.S.C. § 2254
    .       He   contends      that    the    Eighth      Amendment
    prohibition on the execution of intellectually disabled persons,
    as set forth in Atkins v. Virginia, 
    536 U.S. 304
     (2002), and
    Hall v. Florida, 
    134 S. Ct. 1986
     (2014), renders his two death
    sentences unconstitutional.          We affirm.
    I.
    In 2007, a Virginia jury convicted Prieto of two counts of
    capital murder, two counts of use of a firearm in the commission
    of murder, grand larceny, and rape.                Prieto v. Commonwealth, 
    682 S.E.2d 910
    , 914 (Va. 2009) (“Prieto I”). 1                   Discovery of juror
    misconduct at the sentencing phase of the 2007 trial led to a
    mistrial, but in 2008, a second jury convicted Prieto on all
    counts.       
    Id. at 913
    .     During the sentencing phase of his second
    trial, Prieto argued that he was intellectually disabled and
    therefore ineligible for the death penalty under Atkins.                     Prieto
    introduced      substantial      evidence     in   support    of   his    claim    of
    intellectual      disability,     but   the    jury   found   that   he    was    not
    1 The crimes for which Prieto was convicted occurred in
    1988, but Prieto was not linked to the murders until 2005, when
    DNA testing led police to identify him as a suspect. Prieto I,
    682 S.E.2d at 915-16.
    2
    intellectually disabled and imposed the death penalty on the two
    murder counts.      Id. at 914, 916-17.
    On direct appeal, the Supreme Court of Virginia affirmed
    Prieto’s    convictions         but    vacated       his     death   sentences       due   to
    defects in the jury verdict forms at the penalty phase.                              Id. at
    935-36.       In 2010, on remand for resentencing of the capital
    murder    convictions,      a     third    jury          unanimously   recommended         the
    death    penalty    for    both       murder       convictions.        (Prieto    did      not
    argue that he was intellectually disabled at the resentencing.)
    The   state    trial      court       entered       an    order   imposing     the      death
    penalty on both capital murder counts, and the Supreme Court of
    Virginia affirmed both sentences.                        Prieto v. Commonwealth, 
    721 S.E.2d 484
    , 489 (Va.) (“Prieto II”), cert. denied, Prieto v.
    Virginia, 
    133 S. Ct. 244
     (2012).
    Prieto next filed a habeas petition with the Supreme Court
    of Virginia, raising several claims, including contentions that
    his     counsel    was    constitutionally               ineffective     and     that      his
    execution was barred by Atkins.                    See Prieto v. Warden of Sussex
    I State Prison, 
    748 S.E.2d 94
    , 105 (Va. 2013) (“Prieto III”).
    As relevant here, that court held that Prieto could not raise
    his Atkins claim in his state habeas petition because he had
    failed to raise the claim on direct appeal of the 2010 order
    imposing the death sentences.                      
    Id.
         Under Virginia law, that
    failure meant his Atkins claim had been procedurally defaulted.
    3
    
    Id.
       The state habeas court dismissed the remainder of Prieto’s
    claims.     
    Id. at 98
    .
    Pursuant to 
    28 U.S.C. § 2254
    , Prieto then filed the present
    habeas application in federal court, again raising a number of
    claims.     The district court dismissed most of Prieto’s claims as
    meritless;       it   dismissed     his       Atkins     claim        as     procedurally
    defaulted.       We granted a certificate of appealability as to the
    Atkins claim.
    II.
    “Construing and applying the Eighth Amendment in the light
    of our ‘evolving standards of decency,’” the Supreme Court in
    Atkins    held    that    “death   is   not     a     suitable   punishment         for    a
    mentally     retarded 2    criminal.”           
    536 U.S. at 321
       (citation
    omitted).     However, acknowledging the difficulty “in determining
    which offenders are in fact retarded,” the Court “le[ft] to the
    State[s] the task of developing appropriate ways to enforce the
    constitutional        restriction”      on      the     death    penalty         that     it
    announced in Atkins.         
    Id. at 317
     (second alteration in original)
    (internal quotation marks and citation omitted).
    2  Later,  the   Supreme   Court   substituted the   term
    “intellectual disability” for “mental retardation.”   Hall, 
    134 S. Ct. at 1990
    . We do the same, except when quoting from cases,
    statutes, and testimony that use the term “mentally retarded”
    and pre-date the Court’s guidance in Hall.
    4
    Responding to this directive, Virginia enacted a statute
    defining “mentally retarded” as
    a disability, originating before the age of 18 years,
    characterized concurrently by
    (i) significantly subaverage intellectual functioning
    as demonstrated by performance on a standardized
    measure of intellectual functioning administered in
    conformity with accepted professional practice, that
    is at least two standard deviations below the mean and
    (ii) significant limitations in adaptive behavior as
    expressed in conceptual, social and practical adaptive
    skills.
    
    Va. Code Ann. § 19.2-264.3
    :1.1(A).
    Virginia’s highest court interpreted this “two-fold test”
    to require, under the first prong, an IQ score of 70, “below
    which   one     may     be       classified        as    being    mentally       retarded.”
    Johnson v. Commonwealth, 
    591 S.E.2d 47
    , 59 (Va. 2004), vacated
    and remanded on other grounds sub. nom., Johnson v. Virginia,
    
    544 U.S. 901
     (2005).              In other words, the state court held that
    a   defendant    with       an    IQ   score    of      71   or   higher   could    not   be
    “mentally retarded” under Virginia law.
    Last year, however, the Supreme Court clarified in Hall
    that a state that “seeks to execute a man because he scored a 71
    instead of 70 on an IQ test. . . . misconstrues the Court’s
    statements in Atkins.”                 
    134 S. Ct. at 2001
    .            The Court deemed
    unconstitutional        a    Florida      statute        containing    a   “rigid     rule”
    imposing IQ cutoffs for intellectual disability.                           
    Id.
         The Hall
    5
    Court   explained         that    a     state’s     assessment     of     a    defendant’s
    intellectual disability should focus on whether he evidenced,
    beginning     “during            the     developmental          period,”           both    (1)
    “significantly       subaverage          intellectual        functioning,”          and    (2)
    “deficits in adaptive functioning (the inability to learn basic
    skills and adjust behavior to changing circumstances).”                               
    Id. at 1994
    .       The    Court        emphasized         that    these   two     criteria        are
    “interrelated”       and    that        no   “single      factor   [is]    dispositive.”
    
    Id. at 2001
    .        Accordingly, “an individual with an IQ test score
    between 70 and 75 or lower may show intellectual disability by
    presenting        additional           evidence      regarding      difficulties            in
    adaptive functioning.”                 
    Id. at 2000
     (internal quotation marks
    and citation omitted).
    After    Hall,        it     is     clear      that    the    Supreme         Court    of
    Virginia’s    prior        interpretation           of    the   first     prong      of    the
    Virginia statute violates the Eighth Amendment.                           The Hall Court
    said as much, identifying Virginia as one of only two states to
    “have adopted a fixed [IQ] score cutoff identical to Florida’s.”
    
    Id. at 1996
    .         Hall established that a state may not deny a
    defendant     the     opportunity             to     establish      his       intellectual
    disability        based     on         evidence      of     “deficits         in     adaptive
    functioning over his lifetime,” simply because that defendant
    has an IQ score above 70.                     
    Id. at 2001
    .         But the fact that
    Virginia     operated       under        an    unconstitutional           definition        of
    6
    “intellectual      disability”     at        the   time        of    Prieto’s       sentencing
    does not resolve the Atkins inquiry if, as the state habeas
    court    and    the   district    court          held,      Prieto      has      procedurally
    defaulted that claim.          We therefore turn first to that question.
    III.
    A.
    Federal courts “will not review a question of federal law
    decided by a state court” if the state court’s decision rests on
    an    independent     and     adequate       state       law    ground.            Coleman      v.
    Thompson, 
    501 U.S. 722
    , 729-30 (1991).                              When a state habeas
    court declines to address a prisoner’s federal constitutional
    claims    “because      the    prisoner          had     failed       to     meet     a    state
    procedural     requirement[,]      .     .    .    the      state     judgment       rests      on
    independent and adequate state procedural grounds.”                                
    Id. at 730
    .
    In    these    circumstances,     “concerns            of    comity        and     federalism”
    dictate against a federal court’s review of that judgment.                                
    Id.
    In reviewing Prieto’s state habeas petition, the Supreme
    Court of Virginia determined that he had procedurally defaulted
    his   Atkins    claim   because     he       could     have         raised    it    on    direct
    review of his 2010 sentence but had failed to do so.                                See Prieto
    III, 748 S.E.2d at 105.             The court explained that, under the
    procedural rule established by Slayton v. Parrigan, 
    205 S.E.2d 680
    , 682 (Va. 1974), a “non-jurisdictional issue [that] could
    7
    have been raised during the direct appeal process . . . is not
    cognizable in a petition for a writ of habeas corpus.”                           Prieto
    III, 748 S.E.2d at 105.                   We previously have held that this
    precise         Virginia     procedural         default        rule   constitutes       an
    independent and adequate state ground for a denial of a state
    habeas petition.            See Mu’Min v. Pruett, 
    125 F.3d 192
    , 196-97
    (4th Cir. 1997).
    In this appeal, Prieto does not challenge the Supreme Court
    of Virginia’s determination that he defaulted his Atkins claim.
    That is, he does not argue that he actually did raise his Atkins
    claim      on   direct     review.        As    such,    Prieto’s     Atkins   claim    is
    procedurally defaulted, and he is ineligible for relief unless
    one of the two exceptions to procedural default applies.                               See
    Hedrick v. True, 
    443 F.3d 342
    , 366 (4th Cir. 2006).                              Prieto
    asserts that an exception to procedural default saves his Atkins
    claim.
    B.
    A    habeas   petitioner      can       rescue    his    constitutional    claim
    from    procedural       default     if    he       establishes   either   “cause      and
    prejudice” for the default or that the default would yield a
    “fundamental miscarriage of justice.”                     Mackall v. Angelone, 
    131 F.3d 442
    , 445 (4th Cir. 1997) (citing Harris v. Reed, 
    489 U.S. 255
    , 262 (1989)).            In his § 2254 petition before the district
    court, Prieto argued that both exceptions applied to his case.
    8
    Because constitutionally ineffective assistance of counsel
    may provide “cause” for a procedural default, Prieto argued that
    his counsel’s failure to present evidence of his intellectual
    disability at his 2010 resentencing constituted such ineffective
    assistance.        See Murray v. Carrier, 
    477 U.S. 478
    , 488 (1986).
    The   district       court,       however,          found    Prieto’s        ineffective
    assistance claim meritless, and so held that Prieto had failed
    to show “cause and prejudice” excusing the procedural default.
    Prieto does not challenge that ruling in this appeal.                                  As a
    result,     the    only    way     Prieto’s         Atkins     claim       survives     his
    procedural    default      is     through       a   showing    that        enforcing    the
    default would result in a “fundamental miscarriage of justice.”
    See Smith v. Murray, 
    477 U.S. 527
    , 537-38 (1986).
    The    Supreme      Court     has     explained         that     a    “fundamental
    miscarriage of justice” occurs “where a constitutional violation
    has probably resulted in the conviction of one who is actually
    innocent.”    Carrier, 
    477 U.S. at 496
    .                 The Court later clarified
    in Sawyer v. Whitley, 
    505 U.S. 333
    , 341 (1992), that “actual
    innocence” may also mean “innocent of death” in the sentencing
    context.     This means that in a capital case, a habeas petitioner
    can make a showing of “actual innocence,” and qualify for the
    exception,    by    proving      through    “clear      and    convincing       evidence
    that, but for a constitutional error, no reasonable juror would
    9
    have found the petitioner eligible for the death penalty under
    the applicable state law.”         
    Id. at 336
    .
    Prieto does not argue that he is actually innocent of the
    crimes for which he was convicted.             Rather, he argues only that
    he   is   “innocent    of    death.”        Thus,   for   us   to    excuse   his
    procedural    default,       Prieto    must    show   that,    if    instructed
    properly under Hall and Atkins, “no reasonable juror” could have
    found him eligible for the death penalty under Virginia law.
    This presents an extremely high bar. 3
    IV.
    Prieto rests his claim of actual innocence on the Supreme
    Court’s decision in Hall.          Neither we nor the Supreme Court has
    determined    whether       Hall   applies    retroactively     to    cases    on
    collateral review. 4        For purposes of Prieto’s “actual innocence”
    inquiry we will assume without deciding, as the district court
    3 Indeed, the “clear and convincing evidence” standard for
    establishing “actual innocence” in the capital sentencing
    context is “more stringent” than the standard for establishing
    “actual innocence” of the conviction itself.     Schlup v. Delo,
    
    513 U.S. 298
    , 326-27 (1995). The latter requires only a showing
    that “a constitutional violation has probably resulted in the
    conviction of one who is actually innocent.”         
    Id. at 327
    (internal quotation marks and citation omitted).
    4 The two federal appellate courts that have ruled on this
    question to date have held, over dissents, that Hall does not
    apply retroactively on collateral review. See In re: Henry, 
    757 F.3d 1151
    , 1161 (11th Cir. 2014); Goodwin v. Steele, 
    2014 U.S. App. LEXIS 23149
     (8th Cir. 2014) (per curiam).
    10
    did, that Hall does apply retroactively on collateral review.
    Under this assumption, the district court concluded that “Prieto
    has   not    shown    by    clear     and       convincing       evidence      that    no
    reasonable juror would have sentenced him to death because he is
    intellectually       disabled.”       We    review       the    denial    of   Prieto’s
    habeas application de novo.           Hedrick, 
    443 F.3d at 349
    .
    The only evidence that Prieto points to in support of his
    “actual     innocence”     claim    is     the       evidence    introduced      at   the
    sentencing    hearing      following       his    2008    conviction. 5        At     that
    hearing, both Prieto and the Commonwealth offered a good deal of
    evidence as to both prongs of Virginia’s statute:                         intellectual
    functioning and adaptive functioning.                    In his § 2254 petition,
    Prieto focuses on the adaptive functioning evidence.
    That   evidence      included      the     testimony      of    multiple   expert
    witnesses.      Prieto’s chief witness, Dr. Ricardo Weinstein, a
    forensic neuropsychologist with expertise in brain development,
    conducted      “a     comprehensive         evaluation          of      Mr.    Prieto’s
    neuropsychological       functioning”          and    adaptive       functioning.      He
    explained     that     adaptive       functioning          includes       occupational
    5Prieto and the Commonwealth                    filed a joint appendix in
    Prieto’s direct appeal of his 2008                    conviction and sentencing,
    Prieto I. We quote from and rely on                   the materials in that joint
    appendix in discussing the evidence                   presented at Prieto’s 2008
    sentencing.

    skills, activities of daily living, self-esteem, interpersonal
    abilities, self-direction, language, and academic abilities.
    Dr. Weinstein’s evaluation of Prieto’s adaptive functioning
    included interviews with Prieto’s relatives in California and El
    Salvador.          He   also       interviewed        individuals       from    the     El
    Salvadorian government “to understand more about what was going
    on    in   the    country”     when   Prieto     was    a   child.        Prieto      “was
    described as a shy and withdrawn child in adolescence,” and “as
    having     problems     learning      simple      tasks.”         Interviewees        told
    Dr. Weinstein that Prieto “was easily manipulated by relatives
    and   friends”;      kids    his    age   “did    not    like    to    play    with    him
    because . . . he couldn’t understand the rules”; and he had
    “problems acquiring academic skills” and “problems controlling
    his emotions.”          Dr. Weinstein also spent “between twenty and
    thirty hours” over a number of visits with Prieto, administered
    tests to assess Prieto’s behavioral skills, and examined the
    records kept by California prisons on Prieto.
    Dr. Weinstein stated that his research uncovered many risk
    factors     for   adaptive     functioning       deficits       throughout      Prieto’s
    childhood.        In El Salvador, Prieto grew up in extreme poverty,
    characterized by poor nutrition, a lack of running water, and
    little     cognitive     stimulation.            He    suffered       abuse    from    his
    alcoholic father and abandonment by his mother, and he had to
    contend with uncertainty as a result of wars in El Salvador, as
    12
    well    as    witnessing       his   grandfather’s         shooting   death.          After
    Prieto moved to California as a teenager, he began abusing drugs
    and alcohol, was often in trouble with the law, and married his
    pregnant girlfriend at a young age.                      Ultimately, Dr. Weinstein
    opined that Prieto “had adaptive behavior deficits . . . during
    his     developmental       years.”          He     also    opined     that     Prieto’s
    neurological        testing     revealed     “a    brain    dysfunction”       affecting
    areas of the brain “that deal with judgment, deal with being
    able to foresee consequences of behaviors, control sexuality,
    control aggression, . . . [and] are responsible[] for . . .
    empathy.”
    Other      witnesses     for      Prieto    offered      similar      testimony.
    Psychiatrist Dr. Pablo Stewart testified that after meeting with
    Prieto,      he    concluded      that    Prieto     “suffers     from      post     trauma
    stress disorder[,] . . . has impaired cognitive functioning, and
    .   .   .    has    a   history      of   chronic       polysubstance       dependence.”
    Neuropsychiatrist Dr. James Merikangas testified that Prieto’s
    brain    scans      revealed    damage      to    the    areas   of   the     brain    that
    “control one’s emotions, [and] control one’s impulses.”                            Members
    of Prieto’s family, including his mother and siblings, testified
    about the harsh conditions of Prieto’s childhood and about his
    early       development.          Hence,     Prieto’s       defense      at    his     2008
    sentencing included testimony from a wide array of sources about
    the limits of his adaptive functioning.
    13
    At the same time, however, the Commonwealth also presented
    extensive evidence that Prieto’s adaptive functioning was not
    deficient.           The    jury    heard      from     the    prosecution          that     three
    prison       psychologists          had        evaluated        Prieto        when      he     was
    incarcerated in California and that each had concluded that he
    was not intellectually disabled.                        One of these psychologists
    reported       that      Prieto’s     “cognitive           functions         were    adequately
    developed,         and     that    his     level      of      conceptual       thinking        and
    reasoning      were      adequate        for   the    formation         of    good     judgement
    [sic].”      The jury learned that Prieto had written his own prison
    grievances challenging his lack of access to recreation and had
    filed    a     pro    se    legal        challenge      to     the      conditions      of     his
    confinement on Virginia’s death row.                       In these documents, Prieto
    employed      accurate       legal       terminology         and   to    prepare       them,    he
    conducted       self-directed         legal      research.              The    jury    received
    copies    of    Prieto’s          elementary      and      high      school     report       cards
    indicating that he mostly received grades of “good” and ”very
    good.”       The jury was reminded that Prieto acted alone in his
    crimes,      and     that   he     had    exhibited        leadership         abilities       when
    committing prior crimes.
    The prosecution offered its own key witness, clinical and
    forensic psychologist Dr. Leigh Hagan, who interviewed Prieto
    and     reviewed         past      reports      on      him     by      prison        officials,
    Dr. Weinstein, and Dr. Merikangas.                           Dr. Hagan testified that
    14
    Prieto    understood      the      structure    of    jail,        had    a        fairly
    sophisticated vocabulary, could cogently discuss foreign policy
    and political issues, could speak both English and Spanish, and
    did not exhibit significant limitations in his conceptual or
    social    skills.    The    doctor    cited     evidence     that    Prieto         could
    engage    respectfully      with    others,     could       work    within         social
    networks,     had    been       involved       in    intimate        interpersonal
    relationships,      and     could     perform       daily     mathematical            and
    analytical tasks without difficulty.
    Dr. Hagan further highlighted evidence that Prieto had been
    able to obtain driver’s licenses in Virginia and California,
    secure employment, operate power equipment, fly cross-country,
    arrange his own housing, negotiate the purchase of a car, and
    employ aliases to avoid detection.              He noted that Prieto could
    explain “why it was important to have his hair cut for court,”
    because “he understood the value of creating a good impression,”
    reflecting    his    social      awareness.          Ultimately,         Dr.       Hagan
    concluded that Prieto’s “adaptive functioning falls above the
    threshold     of    significant        limitations,”          because         of     his
    “conceptual reasoning, [his] social capacity, and his practical
    skill.”
    In short, although Prieto offered evidence of poor adaptive
    functioning, the Commonwealth also offered compelling evidence
    refuting the existence of any adaptive deficits.                         Prieto does
    15
    not contend that, were he resentenced, he would seek to present
    additional evidence of deficits in his adaptive functioning that
    he did not present at his 2008 sentencing.                    As a result, we are
    left to conclude that a jury at resentencing would face much of
    the same evidence.        Absent some new “smoking gun,” evidence of
    Prieto’s adaptive functioning deficits is at best inconclusive.
    Consequently, Prieto cannot clear the high “actual innocence”
    threshold.       Prieto simply cannot establish that no reasonable
    juror,   faced    with    all    of    this    evidence       as    to   his    adaptive
    functioning, would find him eligible for the death penalty –-
    even if the jury were instructed properly under Hall.
    Perhaps because of this, Prieto argues that the evidence he
    has already presented is similar to the evidence Hall offered to
    prove his intellectual disability.                   But that comparison fails.
    First,    the     Hall    Court        never     concluded          that       Hall     was
    intellectually disabled, so it is unclear how any similarities
    aid   Prieto     in   establishing       his    own     disability.            In     fact,
    instructing that, on remand, Hall should be permitted to present
    evidence of defects in his adaptive functioning, the Supreme
    Court    expressly       noted    that        Hall     “may        or    may     not     be
    intellectually disabled.”             Hall, 
    134 S. Ct. at 2001
    .                Moreover,
    even were Prieto’s case like Hall’s, Prieto is subject to a much
    higher burden of proof because of his procedural default.                              Hall
    did not have to prove he was “actually innocent” of the death
    16
    penalty before the Court could consider the merits of his Eighth
    Amendment claim; Prieto does.
    On    the   record   before    us,    we   cannot   conclude   that    after
    Hall, no reasonable juror would find Prieto eligible for the
    death penalty.      For, “[t]o say that no reasonable juror” would
    have found Prieto eligible for a death sentence, “we would have
    to ignore the totality of evidence,” which included significant
    evidence    that    his   adaptive        functioning    is   not    deficient.
    Calderon v. Thompson, 
    523 U.S. 538
    , 565 (1998).                    And absent a
    showing that he is “actually innocent” of the death penalty,
    Prieto     cannot   overcome       the    procedural     default     that   bars
    consideration on the merits of his Atkins claim. 6
    6 Brumfield v. Cain, No. 13-1433, 576 U.S. –- (June 18,
    2015), issued after oral argument in this case, does not affect
    our holding. The Supreme Court limited its holding in Brumfield
    to an application of Louisiana law to the evidence presented in
    that case.    The Court did not purport to alter its prior
    teachings about intellectual disability, procedural default, or
    the actual innocence exception.   Rather, the Court simply held
    that the state habeas court’s refusal to grant Brumfield an
    evidentiary hearing on his intellectual disability claim, as
    permitted by Louisiana law, was based on “an unreasonable
    determination of the facts” within the meaning of 
    28 U.S.C. § 2254
    (d)(2).     Brumfield,  however,   had  not   procedurally
    defaulted his claim of intellectual disability under Atkins.
    Thus, unlike Prieto, he did not have to prove that he was
    actually innocent of the death penalty before a federal habeas
    court could consider the merits of that claim.          Prieto’s
    procedural default forces him to satisfy this high standard of
    proof, and Brumfield in no way disturbs our conclusion that he
    has failed to do so.

    V.
    The   “fundamental   miscarriage       of   justice”   exception   to
    procedural    default   imposes   a        “demanding”   burden   on   habeas
    petitioners challenging their death sentences.             
    Id. at 559
    .    It
    provides a basis for relief only in “extraordinary instances.”
    McCleskey v. Zant, 
    499 U.S. 467
    , 494 (1991).             Prieto has failed
    to establish that this path around procedural default is open to
    him.    Accordingly, the judgment of the district court is
    AFFIRMED.
