If your Social Security disability hearing includes a vocational expert, that part of the case can feel technical fast. The questions may sound abstract. The jobs listed may not resemble your real-world limitations. And a few minutes of testimony can end up shaping how an Administrative Law Judge views step four, step five, past work, transferable skills, and whether other work exists in significant numbers.
That’s a big reason vocational expert testimony gets so much attention in SSDI and SSI hearings. The good news is that preparation often makes this part of the hearing easier to follow and easier to challenge when the testimony doesn’t line up with the record.
In this post you’ll learn how vocational expert testimony works, what the judge is usually trying to prove, how to prepare your work-history evidence, what questions often matter most, and how an attorney may help identify gaps between the expert’s testimony and your actual limitations. If you want a broader overview of how these witnesses fit into disability hearings, this guide on how job experts affect step-five disability cases gives helpful background.

At a Social Security hearing, the judge may call a vocational expert, often called a VE, to provide impartial testimony about work. The Social Security Administration explains that the ALJ may call a vocational expert to testify, and that the claimant or representative may question that witness during the hearing. The hearing is informal, recorded, and conducted under oath, even though it is not an adversarial courtroom trial in the usual sense (SSA hearing process).
The VE’s role is not to decide whether someone is disabled. Social Security’s own materials say that issue belongs to the ALJ. The VE is there to give evidence about work issues, including past work, skill level, transferability of skills, and whether jobs exist in the national economy for a hypothetical person with certain limitations (SSA VE Handbook, Jan. 6, 2025; SSR 24-3p).
That distinction matters. If the hypothetical question does not accurately reflect your limitations, the answer may not reflect your real ability to work.
In many SSDI and SSI hearings, vocational expert testimony comes up at step four or step five of Social Security’s sequential evaluation process.
At step four, Social Security considers whether a claimant can still perform past relevant work. At step five, Social Security considers whether the claimant can adjust to other work that exists in significant numbers in the national economy, taking into account residual functional capacity, age, education, and work experience (SSR 24-3p).
That is often where the hearing becomes highly specific. The VE may testify about:
Social Security’s updated VE Handbook explains that ALJs often ask more than one hypothetical. One may assume the judge accepts all alleged limitations; another may assume the judge accepts only some of them. The VE is then expected to identify occupations and explain why the hypothetical person could perform them, often with national job-number estimates (SSA VE Handbook, Jan. 6, 2025).
