ALJ Duty to Resolve VE Testimony and DOT SVP Conflicts Under HALLEX I-2-5-59

Direct Answer

The numbered sources provided do not contain HALLEX I-2-5-59, the Dictionary of Occupational Titles, any provision governing an ALJ's duty to inquire into apparent conflicts between vocational expert (VE) testimony and DOT data (including SVP levels), or any authority addressing the resolution of cognitive-demand conflicts between hypothetical limitations and identified occupations. The sources consist exclusively of selected Listings from 20 C.F.R. Part 404, Subpart P, Appendix 1 [2]–[20], [24]–[27], the Grid framework introduction at § 200.00 [1], and individual Grid Rules from Appendix 2 [21]–[23], [28]–[35]. None of these authorities speak to the VE-testimony/DOT-conflict issue raised by the question.

Analysis

What the provided sources do cover. Section 200.00 of the Grid framework addresses the intersection of residual functional capacity with vocational factors (age, education, and work experience) and explains that "[w]here the findings of fact made with respect to a particular individual's vocational factors and residual functional capacity coincide with all of the criteria of a particular rule, the rule directs a conclusion" [1]. The individual Grid Rules supplied—including Rules 201.01, 201.02, 201.04, 201.05, 201.06, 201.09, 201.10, 201.11, 201.12, and 201.18 [21]–[23], [28]–[35]—direct outcomes based on sedentary RFC combined with specified age, education, and work-experience profiles. These are relevant to step-five analysis but do not address the duty to resolve conflicts between VE testimony and DOT job classifications.

What the provided sources do not cover. The question requires authority on:

1. HALLEX I-2-5-59 — the SSA internal instruction governing an ALJ's obligation to identify and elicit explanation of apparent conflicts between VE testimony and the DOT (including SVP and cognitive-demands data). No provision in the numbered sources addresses this.

1. SVP 4.0 and its relationship to cognitive demands — whether an occupation with SVP 4.0 is consistent with a hypothetical limiting the claimant to "simple, repetitive tasks." None of the provided sources contains DOT SVP definitions, General Educational Development (GED) reasoning levels, or any framework for matching SVP to RFC cognitive limitations.

1. The conflict-resolution framework — the procedural steps an ALJ must follow when an apparent conflict exists between the hypothetical's limitations and the VE's identified occupation. No source in the list addresses this procedural duty.

Key Points

• None of the 35 numbered sources contains HALLEX I-2-5-59 or any authority on the ALJ's duty to inquire about apparent VE/DOT conflicts. The sources are limited to medical Listings and Grid Rules [1]–[35].
• The Grid framework introduction at § 200.00 discusses vocational factor analysis but does not address VE testimony, DOT data, or conflict-resolution procedures [1].
• The medical Listings—including those involving cognitive limitations such as Listing 12.02 (neurocognitive disorders) [8], Listing 12.05 (intellectual disorder) [14], and Listing 12.15 (trauma- and stressor-related disorders) [13]—address mental impairment criteria but do not govern the VE/DOT conflict issue presented by the question.
• A practitioner-level answer to the specific question posed would require citation to HALLEX I-2-5-59 itself, the DOT (including the SVP scale and GED reasoning-level definitions), and applicable case law on the ALJ's conflict-resolution duty—none of which appear in the provided source list.
