Comparative Severity: How the SSA Rates Your Work Capacity
TL;DR: Understanding exertional levels from sedentary to very heavy. SSA uses a complex system of medical-vocational rules to decide if you can work. Understanding how age, education, work experience, and physical capacity interact can make or break your claim. ClaimPath builds SSA-compliant documents for $79.
Approval rates at the ALJ hearing level are significantly higher than at the initial or reconsideration stages. Nationally, about 50% of claimants who reach a hearing receive a favorable decision. Claimants with legal representation at hearings win approval at roughly twice the rate of those without representation. Many disability attorneys work on contingency, so there is no upfront cost. Your specific approval odds depend on your medical evidence, your age, your work history, and the particular judge assigned to your case.
How SSA Decides If You Can Work
Understanding exertional levels from sedentary to very heavy.
When SSA cannot approve your claim based on medical evidence alone (meeting or equaling a listing), they use a five-step sequential evaluation. Steps 4 and 5 involve vocational factors:
Step 4: Can You Do Your Past Work?
SSA determines your Residual Functional Capacity (RFC), which describes the maximum you can still do despite your limitations. If your RFC allows you to perform any of your past jobs (as generally performed in the national economy), your claim is denied.
Step 5: Can You Do Any Other Work?
If you cannot do past work, SSA considers whether you can adjust to other work. This is where age, education, and transferable skills matter.
In 2025, SGA is defined as earning more than $1,620 per month (or $2,700 if you are blind). Earning above this amount generally means SSA considers you able to work. The Trial Work Period lets you test your ability to work for 9 months without losing benefits. During this period, you receive full SSDI payments regardless of how much you earn. If you want to try working but are afraid of losing benefits, look into the Ticket to Work program. It provides employment support services at no cost and includes built-in safety nets.
The Grid Rules
SSA's Medical-Vocational Guidelines ("grid rules") are tables that direct decisions based on four factors:
| Factor | Categories |
|---|---|
| RFC/Exertional capacity | Sedentary, light, medium, heavy |
| Age | Under 50, 50-54, 55+ |
| Education | Illiterate, marginal, limited, high school+, college |
| Work experience | Unskilled, semi-skilled (non-transferable), skilled (transferable) |
The grid rules become increasingly favorable with age. A 55-year-old with limited education and unskilled work history who is restricted to sedentary work is directed to be found "disabled" by the grid. A 40-year-old with the same profile may not be.
The SSDI application process takes an average of 3 to 6 months for an initial decision. If denied, the appeals process can add another 12 to 24 months depending on your region. Having complete and detailed medical documentation is the single biggest factor in SSDI approval. Request records from all treating providers before submitting your application. Many claimants benefit from organizing their medical history into a timeline showing how their condition has progressed. This helps SSA reviewers see the full picture without searching through hundreds of pages.
Why This Matters for Your Application
Your work history report needs to accurately describe the physical demands and skill level of your past jobs. Under-reporting demands (making your past work sound easier than it was) hurts you because SSA will conclude you can still do that work. Over-reporting skills hurts you because SSA will argue those skills transfer to other jobs.

Vocational Expert Testimony
At hearings, SSA uses vocational experts (VEs) who testify about what jobs exist in the national economy that match your RFC. The VE's testimony can make or break your case. Understanding how VEs evaluate transferable skills and available jobs is crucial for hearing preparation.
Arrive at your hearing at least 30 minutes early. Bring a government-issued photo ID and any documents you submitted that you want to reference during testimony. Practice describing your daily limitations in concrete terms. Instead of saying 'I can't do much,' say something like 'I can stand for about 10 minutes before the pain forces me to sit down.' According to disability attorneys, the most common mistake at hearings is understating symptoms. Describe your worst days honestly, not just your average days.
How ClaimPath Helps
ClaimPath generates work history descriptions and functional limitation reports in SSA's language for $79. The documents properly characterize your occupational demands and connect your medical limitations to your inability to work. This framing matters enormously for vocational analysis.
Start your ClaimPath application and get your vocational factors documented correctly.

What to Do Next
- Gather your medical records from every provider you have seen in the past 2 years. Request these now, as providers can take 2 to 4 weeks to process records requests.
- Create a my Social Security account at ssa.gov to check your earnings record and estimated benefit amount before applying.
- Write down your daily limitations in specific terms: how long you can sit, stand, walk, lift, and concentrate. You will need these details for the application forms.
