SSR 24-3p in 2026: How the New Vocational Expert Rule Changed SSDI Hearings, Killed SSR 00-4p, and Reshaped Cross-Examination Strategy

By Anthony Albert, Benefits Research Director | Published May 20, 2026 | Updated May 20, 2026

If you've been to an SSDI hearing in the last year, the vocational expert testimony probably looked different than it used to. That's because SSR 24-3p took effect January 6, 2025 and rescinded SSR 00-4p. The change rewrote how VEs cite their sources, how they derive job numbers, and how claimants can challenge their testimony. It also widened the field of acceptable occupational information beyond the Dictionary of Occupational Titles, which hasn't been updated since 1991.

For represented claimants, SSR 24-3p creates both an opportunity and a risk. The opportunity is that VEs now have to put their methodology on the table in a way they didn't before. The risk is that the old SSR 00-4p conflict resolution playbook (where the ALJ had to reconcile VE testimony with the DOT) no longer applies. If you're going into a hearing in 2026 without a working understanding of the new rule, you're flying blind.

What SSR 24-3p Actually Did

SSR 24-3p was published in the Federal Register on December 6, 2024, with an effective date of January 6, 2025. The full title is "Titles II and XVI: Use of Occupational Information and Vocational Specialist and Vocational Expert Evidence in Disability Determinations and Decisions."

Three big things happened:

1. SSR 00-4p was rescinded. The 2000 ruling that required ALJs to identify and resolve conflicts between VE testimony and the DOT is no longer in effect.
2. The DOT is no longer the controlling source. SSA continues to recognize the DOT as valid and reliable, but VEs may now rely on other sources too. ORS, OEWS, ONET, SkillTRAN, Job Browser Pro, and professional experience are all acceptable.
3. VEs have a new duty to identify sources and explain methodology. The ruling requires VEs to identify the data sources they relied on and to explain their general approach to job number estimates. Definitional differences across sources have to be acknowledged.

The ruling applies to all new applications filed on or after January 6, 2025 and to all claims pending on or after that date. Cases heard before the effective date but not yet decided get SSR 24-3p applied in the decision. Federal court cases use the rule in effect at the time of the agency decision, but any remand from federal court triggers SSR 24-3p for the entire period at issue.

Why SSR 00-4p Had to Go

SSR 00-4p was written in 2000. It required adjudicators to:

• Identify and obtain a reasonable explanation for any conflicts between VE evidence and the DOT.
• Explain in the determination or decision how any conflict that had been identified was resolved.
• Ask the VE on the record whether the testimony conflicted with the DOT.
• Resolve conflicts before relying on VE evidence.

The system worked when the DOT was current. By 2025 the DOT had been frozen for 34 years. Many DOT job titles described work that no longer existed, had been automated, or had changed substantially. Document preparer (microfilm), surveillance system monitor, addresser, and dozens of other classic DOT picks for sedentary unskilled work raised obsolescence challenges in case after case.

SSA had been working on a replacement for the DOT since the mid-2010s. The Occupational Information System project funded the BLS to build the Occupational Requirements Survey. ORS launched in 2015 and reached full operational status by the late 2010s. By 2024 SSA had enough ORS data to incorporate into the regulatory framework without abandoning the DOT entirely. SSR 24-3p is the bridge.

The New Universe of Acceptable Sources

Under SSR 24-3p, VEs may rely on any of the following:

Source	What It Is	Strengths and Weaknesses
DOT	Dictionary of Occupational Titles, published by DOL, last updated 1991	Strong on detailed job descriptions and SVP. Weak on currency. Many obsolete or transformed jobs.
SCO	Selected Characteristics of Occupations, DOT companion publication	Provides physical demand and environmental data tied to DOT codes. Same currency problem as DOT.
ORS	Occupational Requirements Survey from BLS, partnership with SSA	Current physical, cognitive, education, and environmental data. Less detail than DOT on specific tasks.
OEWS	Occupational Employment and Wage Statistics from BLS	Current job number data tied to SOC codes. Numbers can be translated to DOT codes but the mapping is imperfect.
ONET	Occupational Information Network, DOL successor to DOT	Current and updated regularly. Uses Job Zones instead of SVP, which doesn't map cleanly onto SSA regulations.
SkillTRAN / Job Browser Pro	Commercial software that aggregates DOT, ONET, and BLS data	Convenient for VEs. Methodology opaque. Often challenged in cross-examination.
Professional experience	The VE's own knowledge from job placement, vocational rehabilitation, or labor market analysis	Permitted as one input. Cannot stand alone reliably.

The opening of the source universe is the most consequential change. VEs are no longer locked into the DOT. They can cite multiple sources, blend them, and arrive at job number estimates that don't map cleanly to any single source. The trade-off is that they have to explain themselves.

The Source Identification Requirement

SSR 24-3p says VEs must identify the source of the data they use. That sounds simple but it shifts the burden of disclosure onto the VE in a way SSR 00-4p didn't.

Under the old rule, a VE could testify to job numbers and the ALJ's job was to ask whether the numbers conflicted with the DOT. Under the new rule, the VE has to put the source on the table from the start. If the VE relies on SkillTRAN, they have to say SkillTRAN. If they use OEWS data tied to SOC codes, they have to identify the SOC codes. If they rely on personal labor market knowledge from a particular state, they have to name that.

This matters in cross-examination. The first question to ask a VE in 2026 is "What sources of occupational data did you rely on for your testimony today?" Get a clean answer. If the VE hedges or says "the DOT and my experience," push for specifics. Did they use ORS? Did they consult ONET? Are they relying on SkillTRAN for the job numbers? Each answer opens a follow-up.

The Methodology Explanation Requirement

SSR 24-3p also requires VEs to explain their general approach to deriving job numbers. This is the bigger procedural shift. Under SSR 00-4p, a VE could give a job number and as long as it didn't conflict with the DOT in some obvious way, the testimony stood. Under SSR 24-3p, the VE has to be able to explain how they got from raw data to the number they cited.

The most common methodology issue is the SOC-to-DOT mapping problem. BLS publishes job numbers by SOC codes (Standard Occupational Classification). Each SOC code can cover dozens of DOT codes. When a VE identifies a DOT job title and gives a job number, they're typically allocating a fraction of the SOC code's total employment to that DOT title. The fraction is often arbitrary or based on assumptions the VE can't fully document.

Under SSR 24-3p, the VE has to explain how they did the allocation. They don't have to disclose proprietary algorithms or trade secrets, but they do have to give a general explanation that lets the claimant evaluate the reliability of the estimate. If a VE refuses to explain the methodology, the testimony may not constitute substantial evidence under Biestek v Berryhill (2019).

What Biestek v Berryhill Means After SSR 24-3p

The Supreme Court decided Biestek in 2019. The case asked whether a VE's testimony could constitute substantial evidence when the VE refused to disclose the data underlying their job number estimates. The Court held that there's no categorical rule. The inquiry is case-by-case, looking at all the features of the expert's testimony and the rest of the administrative record.

That language was workable under SSR 00-4p because the DOT served as a fallback reference point. Even if the VE refused to disclose their data, the ALJ could compare the testimony to the DOT and check for obvious conflicts.

Under SSR 24-3p the analysis is different. The DOT is no longer the fallback. The reliability of VE testimony depends on the VE's identification of sources and explanation of methodology. If a VE refuses to identify sources or explain methodology, the testimony arguably falls below the substantial evidence threshold under the new ruling. Claimant counsel should be preserving this issue at every hearing where a VE hedges on disclosure.

Definitional Differences Across Sources

One of the trickier parts of SSR 24-3p is the requirement that VEs address definitional differences. SSA's regulations define exertion levels (sedentary, light, medium, heavy, very heavy), skill levels (unskilled, semi-skilled, skilled), and education levels (illiterate, limited, high school, more than high school) in specific ways. The DOT uses one set of definitions. ORS uses partially overlapping definitions. ONET uses Job Zones for skill, which don't match SVP.

Common definitional issues:

• Light work. SSA defines light work as up to 20 pounds occasional, 10 pounds frequent, or significant walking and standing. ORS measures lifting frequency differently. ONET doesn't always classify in the same buckets.
• Sedentary work. SSA's sedentary definition includes occasional walking and standing. Some ORS data points suggest most jobs classified as sedentary in the DOT actually require more standing or walking in practice.
• Skill levels. SVP 1 and SVP 2 (unskilled) map onto Job Zones 1 and 2 but not perfectly. Job Zone 2 includes some jobs SSA would treat as semi-skilled.
• Reasoning levels. The DOT uses GED reasoning levels 1 through 6. Job Zones use a different breakdown. Translating between them requires assumptions.

When a VE cites a source that uses a different definition, SSR 24-3p says they must explain how they accounted for the difference. If they didn't, the ALJ should ask. If the ALJ doesn't ask, claimant counsel should ask on cross.

The Obsolete Jobs Problem

The DOT was published in 1991. The classic obsolete DOT jobs that VEs still cite include:

• Document Preparer, Microfilming (DOT 249.587-018). A sedentary unskilled job that prepared paper documents for microfilm. Microfilming has been replaced by digital scanning. The job barely exists in 2026.
• Surveillance System Monitor (DOT 379.367-010). A sedentary unskilled job that watched security camera feeds. Modern surveillance is automated with motion detection and AI.
• Addresser (DOT 209.587-010). Hand-addressing envelopes for mail. Replaced by computerized printing decades ago.
• Order Clerk, Food and Beverage (DOT 209.567-014). Taking phone orders for food delivery. Largely replaced by app-based ordering.
• Cuff Folder (DOT 685.687-014). A sedentary unskilled garment manufacturing job. Most garment manufacturing has moved offshore or been automated.

Under SSR 00-4p, challenging these jobs as obsolete required a fight with the DOT designation. Under SSR 24-3p, you can use ORS or OEWS data to show that the job either doesn't exist in significant numbers anymore or has been transformed so much that the DOT description no longer fits. The new ruling gives claimant counsel more tools to push back.

Cross-Examination Strategy in 2026

The basic structure of cross-examination has changed. Here's a workable approach.

Opening Round: Source Identification

Ask the VE to identify every source of occupational data they relied on for the testimony. Get DOT codes, ORS data points, OEWS SOC codes, ONET references, SkillTRAN reports, and personal experience all named on the record. Don't accept generic answers like "the usual sources." Push for specifics.

Second Round: Methodology Explanation

Ask the VE to explain how they got from raw data to the job numbers they cited. If they used OEWS data tied to SOC codes, ask how they translated to DOT codes. If they used SkillTRAN, ask how the software allocates SOC counts. If they used personal experience, ask which labor market and which time period.

Third Round: Definitional Reconciliation

Ask the VE whether the sources they used define exertion, skill, and education the same way as SSA regulations. Press for specific differences. Ask how they accounted for the differences in their job number estimates.

Fourth Round: Hypothetical Testing

Run the ALJ's hypothetical RFC through. Get the specific occupations the VE identified. For each one, walk through: DOT code, SVP, exertion level, reasoning level, and job numbers. Probe weak spots. If the hypothetical includes occasional fingering and the DOT job requires frequent fingering, get the conflict on the record.

Fifth Round: Obsolescence Challenge

If any of the cited jobs are classic obsolete DOT jobs, challenge them. Ask whether the job exists in significant numbers in the current economy. Cite ORS data or OEWS data that shows declining or near-zero employment. The VE doesn't have to agree but the record builds.

Closing Round: Reliability Challenge

If the VE hedges on sources, methodology, or definitions, sharpen the question. Ask directly: "Can you confirm that the job numbers you cited today are based on identified data sources with methodology you can explain?" If the VE says no or hedges, that's a Biestek-style challenge for federal court.

What This Means for the ALJ Decision

The ALJ still has to find substantial evidence at step five before denying a claim. SSR 24-3p doesn't change that. What changed is what counts as substantial evidence in the VE context.

Under SSR 00-4p the decision had to identify and resolve conflicts with the DOT. Under SSR 24-3p the decision should:

• Identify the VE's sources of occupational data.
• Note the VE's general approach to job number estimates.
• Address any definitional differences the VE acknowledged.
• Explain why the VE testimony is reliable given the sources cited.

If the ALJ skips these steps, the decision may not be supported by substantial evidence under the new ruling. Empire Justice Center and other claimant-side groups have been pushing this argument since the ruling took effect.

Federal Court Implications

At federal court the substantial evidence standard applies. A district court reviews the agency record to determine whether the ALJ's findings are supported by relevant evidence a reasonable mind might accept as adequate.

Three federal court themes are emerging in early 2026 cases:

1. Inadequate source identification. When the ALJ relies on a VE who didn't identify sources, courts are remanding.
2. Inadequate methodology explanation. When the VE's job number derivation is opaque and the ALJ doesn't probe it, remands are common.
3. Failure to address definitional conflicts. When the VE cites sources with different definitions of exertion or skill and doesn't reconcile, courts are flagging it.

The Ninth Circuit's Powley v Bisignano opinion from March 2026 walked through some of this. The Sixth Circuit and Seventh Circuit have been active in the area too. Expect more published opinions through 2026 as remanded cases come back through the pipeline.

What Claimants Should Do Differently

If you have a hearing coming up in 2026, the practical changes are:

1. Get a representative who understands SSR 24-3p. The cross-examination is more technical than under SSR 00-4p. A claimant going pro se against a vocational expert in 2026 is at a real disadvantage. See our piece on representative appointment.
2. Prep the cross-examination in advance. Don't show up at hearing without a question list. Identify the obsolete jobs likely to come up given your RFC. Pull ORS data points where they help your case.
3. Bring source materials. If you're going to challenge DOT obsolescence, have the ORS or OEWS data printed. ALJs respect a claimant who comes prepared.
4. Submit a post-hearing brief. SSR 24-3p creates more issues to write about. A two to three page post-hearing brief that walks through the VE's source identification, methodology, and definitional issues can shift the outcome.
5. Preserve issues for appeal. If the ALJ denies despite weak VE testimony, get the issues on the record cleanly. The Appeals Council and federal court reviewers will look for them.

Common Mistakes

1. Assuming SSR 00-4p still applies. It doesn't. Don't waste cross-examination time asking the VE to reconcile testimony with the DOT in the old way. That's not the test anymore.
2. Not asking the VE to identify sources. This is the foundational question under SSR 24-3p. If you don't ask, you've forfeited the most important line of cross.
3. Ignoring methodology questions. Job number estimates are the most challenged piece of VE testimony. The methodology is often the weak spot.
4. Missing the obsolescence opportunity. The new ruling opens up DOT obsolescence challenges that the old ruling didn't really permit. Use them.
5. Skipping the post-hearing brief. ALJs read briefs. A clean SSR 24-3p brief that identifies weak spots gives the ALJ a path to a favorable decision and preserves issues if they deny.

State-Level Patterns

SSR 24-3p is a federal ruling so it applies the same everywhere. But the local labor market data that gets cited under the new ruling varies dramatically. VEs in rural West Virginia or Mississippi hearings often cite national OEWS data that doesn't reflect the actual jobs available locally. Counsel can push on this. ORS and OEWS data are national or regional, not county-level, so local job availability is often an unaddressed issue.

In larger metros (New York, Illinois, California), the diversity of the labor market makes obsolescence challenges harder. There are more jobs in more sectors and the VE has more options to fall back on.

Frequently Asked Questions

What is SSR 24-3p?

SSR 24-3p is a Social Security Ruling issued December 6, 2024 that took effect January 6, 2025. It rescinded SSR 00-4p, which had required ALJs to identify and resolve conflicts between vocational expert testimony and the Dictionary of Occupational Titles. SSR 24-3p applies to all new applications filed on or after January 6, 2025 and to all claims pending on or after that date.

How did SSR 24-3p change vocational expert testimony?

SSR 24-3p ended the strict requirement that VE testimony be reconciled with the DOT. VEs may now rely on the DOT, the Occupational Requirements Survey, the Occupational Employment and Wage Statistics, ONET, SkillTRAN, Job Browser Pro, and their own professional experience. SSA expects VEs to identify their sources and explain their general approach to deriving job numbers, but the affirmative duty to resolve conflicts with the DOT is gone.

Does the DOT still matter under SSR 24-3p?

Yes. SSA continues to recognize the DOT as a valid and reliable source of occupational information. The DOT remains an administratively noticed publication under 20 CFR 404.1566(d). What changed is that the DOT is no longer the only controlling source. A VE may cite ORS, OEWS, ONET, or other sources alongside or instead of the DOT, as long as the VE identifies the source and accounts for definitional differences.

What is the Occupational Requirements Survey?

The Occupational Requirements Survey, or ORS, is a Bureau of Labor Statistics survey conducted in partnership with SSA. ORS collects data on physical demands, cognitive demands, environmental conditions, education and training requirements, and other job characteristics that matter for disability determinations. ORS data has been used to address gaps in the DOT, which has not been updated since 1991. SSR 24-3p formally recognizes ORS as a source VEs may rely on.

Do VEs still have to resolve conflicts with the DOT?

Not in the same way. Under SSR 00-4p the ALJ had an affirmative duty to ask about conflicts between VE testimony and the DOT and to elicit a reasonable explanation before relying on the VE. SSR 24-3p replaces that with a softer rule. The VE must identify their data sources and explain their general approach. If sources use different definitions, the VE must explain how they accounted for the differences. The affirmative conflict resolution duty is gone.

Can a VE rely entirely on personal experience under SSR 24-3p?

Not entirely. SSR 24-3p permits VEs to rely on professional experience as one input, but expects them to cite at least one external source of occupational information. The Supreme Court's decision in Biestek v Berryhill (2019) held that a VE's word alone can constitute substantial evidence in some cases, but the practical effect of SSR 24-3p is to push VEs toward citing external data sources to support their conclusions.

How do I challenge VE testimony at a hearing in 2026?

Ask the VE to identify their sources of occupational information. Ask them to explain how they derived job numbers from those sources. Probe definitional differences between sources and SSA regulations. Test job numbers against the hypothetical RFC. Challenge occupations that have changed substantially since the DOT was last updated in 1991. Build the record for a Biestek-style substantial evidence challenge on appeal if the VE refuses to identify methodology or sources.

SSR 24-3p is the most consequential procedural change in SSDI hearings since the 2017 medical opinion regulations. It opens VE testimony up to a new style of cross-examination and makes job number reliability a live issue in every step-five case. Claimants who walk into hearings prepared for the new rule have a real edge. Claimants who don't are at the mercy of whatever the VE says.
