[SSA / SSDI](https://research.superinsight.me/research/ssa) / thread # Listing 12.05B: Evaluating IQ 71, Severe Adaptive Deficits, and SSR 16-3p 8/29/2026 Question Under Listing 12.05B, how does an ALJ evaluate a hypothetical claimant's intellectual disability when a valid Wechsler Adult Intelligence Scale yields a full-scale IQ score of 71, but the claimant exhibits severe deficits in adaptive functioning that manifested prior to age 22? How does SSR 16-3p apply to weighing medical source opinions regarding the severity of these adaptive deficits when the objective testing marginally exceeds the listing's threshold? Answer #### Direct Answer Source [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05) provides the text of Listing 12.05, which states the listing is "satisfied by A or B." The available source includes the full operative text of **paragraph A** but does **not** include the text of **paragraph B**. Accordingly, the specific IQ numerical threshold in paragraph B and its precise operative language cannot be quoted or analyzed from the provided materials. What the source does establish is the listing's overall two-path structure and the three core elements that paragraph A requires—each of which informs the ALJ's evaluation framework even when paragraph B governs. Additionally, **SSR 16-3p is not among the provided sources**, so its specific guidance on weighing medical source opinions cannot be addressed from the materials furnished. #### Analysis #### Listing 12.05 Structure Listing 12.05 provides that an intellectual disorder (see 12.00B4) is "satisfied by A or B" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). This disjunctive structure means the ALJ must evaluate which paragraph applies based on the evidence. Paragraph A applies where the claimant demonstrates "significantly subaverage general intellectual functioning evident in your cognitive inability to function at a level required to participate in standardized testing of intellectual functioning" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). Paragraph B—referenced in the listing's "A or B" formulation but whose text is not included in the provided source—would govern where standardized testing was administered and yielded a scorable result, as is the case with the hypothetical WAIS full-scale IQ of 71. #### The Three Core Requirements Under Paragraph A Although paragraph B's text is not provided, paragraph A's three requirements illuminate the listing's analytical architecture, which an ALJ would apply across both paths: **1. Significantly subaverage general intellectual functioning.** Paragraph A frames this as evident in "cognitive inability to function at a level required to participate in standardized testing" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). Where paragraph B applies, the intellectual functioning prong would be evaluated through the standardized test result rather than through the inability to test. **2. Significant deficits in adaptive functioning.** The listing requires "significant deficits in adaptive functioning currently manifested by your dependence upon others for personal needs (for example, toileting, eating, dressing, or bathing)" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). This is a distinct and independent criterion from the intellectual functioning measure. The listing specifies that the deficits must be "currently manifested" and gives concrete examples of the level of impairment contemplated—dependence on others for basic personal needs [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). An ALJ evaluating the hypothetical claimant must therefore assess whether the severe adaptive deficits documented in the record meet this standard, independent of the IQ score. **3. Onset prior to age 22.** The listing requires that "the evidence about your current intellectual and adaptive functioning and about the history of your disorder demonstrates or supports the conclusion that the disorder began prior to your attainment of age 22" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). Note the dual evidentiary standard: the evidence must "demonstrate or support" pre-age-22 onset—language that permits a finding based on supportive (as opposed to conclusively demonstrative) evidence [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). #### Evaluating the IQ Score of 71 The hypothetical presents a WAIS full-scale IQ of 71, which the question characterizes as marginally exceeding the listing's threshold. Because the operative text of paragraph B is not included in the provided source [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05), the specific numerical cutoff and any language regarding margins of error, confidence intervals, or the " Flynn effect" cannot be quoted or analyzed from these materials. The ALJ's evaluation would, however, proceed under the paragraph B framework (since the claimant was able to participate in standardized testing, unlike the claimant contemplated by paragraph A [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05)). #### The Role of Adaptive Functioning Deficits The listing treats adaptive functioning as a standalone prong. Paragraph A's formulation—"significant deficits in adaptive functioning currently manifested by your dependence upon others for personal needs (for example, toileting, eating, dressing, or bathing)" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05)—establishes that the ALJ must independently evaluate whether the claimant's adaptive deficits satisfy the listing's severity standard. The question's premise that the claimant exhibits "severe deficits in adaptive functioning" implicates this prong directly. The ALJ would need to determine whether those deficits rise to the level of "dependence upon others for personal needs" as illustrated by the listing's examples [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). The listing's cross-references to "12.00B4" and "12.00H" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05) suggest additional programmatic instructions governing the evaluation of intellectual disorders, but those sections are not among the provided sources. #### SSR 16-3p and Medical Source Opinions SSR 16-3p, which addresses how SSA adjudicators evaluate medical source opinions and other evidence, is not included in the provided source list. Its specific requirements regarding consistency, supportability, and the relationship between medical opinions and the claimant's reported symptoms therefore cannot be analyzed from the materials furnished. An ALJ weighing competing medical source opinions on the severity of adaptive deficits would apply SSR 16-3p's framework, but the content of that ruling must be drawn from sources outside this set. #### Key Points - Listing 12.05 is "satisfied by A or B" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05); paragraph A's text is provided, but paragraph B's operative text is not included in the available source. - Paragraph A applies where the claimant has "cognitive inability to function at a level required to participate in standardized testing" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05); where standardized testing yields a scorable result, paragraph B governs. - The adaptive functioning prong requires "significant deficits" "currently manifested by your dependence upon others for personal needs (for example, toileting, eating, dressing, or bathing)" [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05)—an independent criterion the ALJ must evaluate separately from the intellectual functioning measure. - Onset before age 22 must be shown by evidence that "demonstrates or supports" pre-age-22 onset [\[1\]](https://lib.superinsight.me/v/2026-07-02/ssa/listings/12.00-mental-disorders#12.05). - SSR 16-3p is not among the provided sources and cannot be analyzed from these materials; a follow-up inquiry with that ruling and the full text of Listing 12.05B would allow a more complete analysis of the ALJ's obligations when the IQ score marginally exceeds the listing threshold.
