What are the GRID rules?
When SSA gets to Step 5 of the disability evaluation, the question becomes: can you adjust to other work in the national economy? The Medical-Vocational Guidelines, what everybody calls the GRID, answer that question by cross-referencing your age, education, and past work. The cell you land in either directs an approval or directs a denial.

What are the GRID rules?
The GRID rules are SSA's Medical-Vocational Guidelines, found at 20 CFR Part 404 Subpart P Appendix 2. They sit at Step 5 of the five-step disability evaluation. SSA matches your age category, education level, and past work against tables for sedentary, light, or medium exertional capacity. Some cells direct a finding of disabled; others direct not disabled.
If your disability claim involves Medicare timing once you are approved, a licensed advisor can walk you through what comes next.
Free help from licensed Medicare advisors
Once SSDI approval comes, Medicare entitlement follows after the 24-month qualifying period. Chapter's licensed Medicare advisors help disabled beneficiaries sort out Original Medicare versus alternatives without pushing a specific plan. The service is free.
Here's what to do, in 4 steps.
Before you or your representative argue the GRID, get four things on paper: your age category as of the alleged onset date, your highest level of education, a clean list of past work over the last fifteen years, and your residual functional capacity. Those four inputs drive every cell on every table.
1. Identify your age category
Pin down which GRID age bracket you fall into as of your alleged onset date: Younger (18-49), Closely Approaching Advanced Age (50-54), Advanced Age (55-59), or Closely Approaching Retirement Age (60+). The category drives which row of the table SSA reads.
20 CFR 404.1563 (age categories) ›2. Document your highest education
Write down your highest grade completed, whether you have a high school diploma or GED, and whether your formal education trained you for skilled work. The education brackets in the GRID range from illiterate or unable to communicate in English up through high school plus transferable skills.
20 CFR 404.1564 (education) ›3. List past work in detail
Build a job-by-job list covering the relevant 15-year past relevant work window. For each job note duties, physical demands, skill level (unskilled, semi-skilled, skilled), and whether the skills could transfer. SSA will classify this work itself, but a clean list keeps the record accurate.
20 CFR 404.1565 (past relevant work) ›4. Watch the borderline-age window
If you will turn 50, 55, or 60 within roughly six months of any decision point, raise the borderline-age issue in writing. Under POMS DI 25015.005, SSA may use the higher age category when the claimant is borderline, but they will not always raise it on their own.
POMS DI 25015.005 (borderline age) ›The four age categories that drive the GRID
Which of these sounds more like you?
The GRID is age-driven. Pick the situation that lines up with where you are in life and at what exertional level you can still function.
I'm 49 and disabledYounger person, sedentary or light RFC
At 49 you fall in the Younger person category, which is the toughest cohort for the GRID. Even at sedentary RFC, the tables generally direct a finding of not disabled because SSA assumes a younger worker can adjust to other unskilled work.
That doesn't end your case. Non-exertional limitations (mental, manipulative, environmental) still get evaluated under SSR 83-14, and a Listings-level severity at Step 3 bypasses the GRID entirely. Talk to a representative if your initial denial cited only the GRID rules.
If you're 49 and the application is dragging, the calendar may move you into the next age category before the decision. That can flip the outcome. Don't let SSA close the file based on your age at filing if you're now 50.
I'm 50 and disabledClosely approaching advanced age
At 50 you cross into Closely Approaching Advanced Age. Several GRID cells at sedentary RFC start directing a finding of disabled at this category that would have directed not disabled the day before your fiftieth birthday.
If you have limited education and unskilled past work and can only do sedentary, Rule 201.09 may direct disabled. The exact cell depends on the combination, but turning 50 is a real cliff in the case law.
I've seen people apply at 49 and get denied, then re-apply at 50 with the exact same medical record and get approved. The GRID is that age-sensitive. If you're close to a category change, raise borderline age in writing.
I'm 55 or older and disabledAdvanced age, 55-59
At 55 you reach Advanced Age. The GRID treats advanced-age claimants very favorably. Rules at sedentary and light RFC frequently direct a finding of disabled, especially when education is limited and past work was unskilled or semi-skilled with no transferable skills.
The transferability question becomes load-bearing here. If SSA finds your skills transfer to other work you can still do, the GRID may direct not disabled even at 55. Push back on transferability findings if the destination jobs require significant adjustment.
I'm 60 or older and disabledClosely approaching retirement age
At 60 you enter Closely Approaching Retirement Age. The GRID is at its most favorable here. Rule 201.01 directs disabled at sedentary RFC for many education and work-history combinations. Rule 202.01 does similar work at light RFC.
Transferable-skills analysis is also stricter at this age. SSA must show very little vocational adjustment is required, not just that some skills could theoretically transfer.
I have only a sixth-grade educationLimited or marginal education
Education brackets in 20 CFR 404.1564 distinguish illiterate or unable to communicate in English, marginal (no formal schooling or up through 6th grade), limited (7th through 11th grade), high school, and high school plus transferable skills or recent training.
Lower education brackets generally favor a GRID approval, especially combined with advanced age and unskilled past work. SSA looks at the highest grade completed and at functional literacy, not just years of schooling.
I have a college degreeHigher education with skilled past work
A college degree plus skilled past work is the hardest combination at the GRID. SSA may find you have transferable skills usable in sedentary occupations, which directs not disabled even at advanced age.
This is where vocational expert testimony becomes load-bearing. If you cannot perform the destination jobs the VE identifies, your representative can challenge transferability under SSR 82-41 and POMS DI 25015.017. The GRID does not assume a college degree always finds work.
If you have higher education and skilled past work, get a disability representative involved before the hearing. Transferable-skills analysis is technical, and a vocational expert's testimony usually decides Step 5 in this scenario.
I'm helping a parent or spouse with their caseBystander
Bystanders carrying a Step 5 case for someone else need three documents in hand before any hearing or reconsideration: a clean education record (highest grade, any GED, vocational training), a 15-year past work history with duties and exertional demands, and the alleged onset date plus exact birth date.
The borderline-age question is the most common thing bystanders catch that the claimant misses. If your loved one is within months of 50, 55, or 60, raise it in writing. POMS DI 25015.005 says SSA may use the higher category but does not always do so on its own.
My situation doesn't fit any of theseFallback
GRID outcomes turn on the specific combination of age, education, RFC, and past work. If none of the situations above match, it usually means your case is at a hybrid cell or has significant non-exertional limitations that Rule 204.00 or SSR 83-14 governs instead.
Non-exertional limitations (mental, postural, manipulative, visual, communicative, environmental) are not directly resolved by the tables. They get evaluated alongside the GRID under SSR 83-14, which frames the decision rather than directing it. A representative can read the actual table cells against your specific facts.
Programs that interact with a disability claim
Whether your GRID outcome ends in approval or denial, several adjacent programs may be in play. The same medical record can support more than one application.
Five-step disability evaluation
The GRID is Step 5. The full sequential evaluation runs Step 1 (substantial gainful activity) through Step 4 (past relevant work) before reaching the GRID. Understanding the order helps you spot which step actually drove a denial.
Blue Book listings
If your impairment meets or medically equals a Blue Book listing at Step 3, SSA approves disability without ever reaching the GRID. Worth checking the Listings before assuming the case turns on Step 5.
Residual functional capacity (RFC)
Your RFC determines which GRID table SSA reads: Table 1 (sedentary), Table 2 (light), or Table 3 (medium). Without an accurate RFC the GRID outcome is meaningless. The RFC assessment runs under 20 CFR 404.1545 and SSR 96-8p.
Past relevant work (Step 4)
Step 4 asks whether you can return to past relevant work. If yes, the case ends at Step 4 and never reaches the GRID. If no, the inability to return to past work is what triggers the Step 5 GRID analysis.
SSDI eligibility basics
GRID outcomes apply only after the claimant clears the SSDI insured-status and substantial-gainful-activity gates. You may qualify for SSDI if you have sufficient work credits and a medically determinable impairment expected to last 12 months or result in death.
SSI disability
The same GRID applies to SSI disability claims under 20 CFR 416.969. If your SSDI insured status has lapsed, you may still qualify for SSI on the same medical record, with means-tested income and resource limits.
Everything people ask me
What is the GRID?
The GRID is the everyday name for the Medical-Vocational Guidelines, codified at 20 CFR Part 404 Subpart P Appendix 2. It is a decision matrix used at Step 5 of the five-step disability evaluation. SSA matches your age, education, and past work against tables for sedentary, light, and medium residual functional capacity to direct an approval or denial.
Why is turning 50 such a big deal?
Several GRID cells direct an approval at age 50 to 54 that direct a denial at age 18 to 49 with the same RFC, education, and work history. Crossing into the Closely Approaching Advanced Age category narrows the range of work SSA assumes you can adjust to. The same medical record can flip outcomes simply because of the age category change.
What are the GRID age categories?
Per 20 CFR 404.1563: Younger person (18 through 49), Closely Approaching Advanced Age (50 through 54), Advanced Age (55 through 59), and Closely Approaching Retirement Age (60 and older). Each category triggers different cells in Tables 1, 2, and 3 of Appendix 2.
What if I'm 49 and 11 months?
POMS DI 25015.005 lets SSA use the higher age category when a claimant is borderline. There is no fixed cutoff for what counts as borderline, but cases within roughly six months of a category change are commonly raised. SSA must consider it but does not always raise it on its own; raise it in writing through your representative.
Does my education level matter?
Yes. 20 CFR 404.1564 sets the brackets: illiterate or unable to communicate in English, marginal (no formal schooling or up through 6th grade), limited (7th through 11th grade), high school, and high school plus transferable skills or recent training. Lower education brackets generally favor a GRID approval, especially combined with advanced age.
What are transferable skills?
Transferable skills are skills from past work that could be used in other jobs the claimant could perform with current RFC. POMS DI 25015.017 and SSR 82-41 govern the analysis. Transferability is usually established through Vocational Expert testimony at the hearing. The standard tightens at advanced age and closely approaching retirement age.
Does the GRID apply if I have non-exertional limits?
Pure GRID applies only to exertional limits. Non-exertional limitations (mental, postural, manipulative, visual, communicative, environmental) require the SSR 83-14 framework. The GRID still frames the decision but does not directly resolve it. Rule 204.00 in Appendix 2 specifically governs cases with non-exertional limits and no significant exertional limits.
Can I appeal a Step 5 denial?
Yes. File Reconsideration within 60 days of the initial denial, then request a hearing before an Administrative Law Judge if Reconsideration also denies. ALJ-level review often re-examines the GRID application more carefully, and some Step 5 denials get reversed at hearing.
Where can I read the GRID tables myself?
20 CFR Part 404 Subpart P Appendix 2 is publicly available at ssa.gov/OP_Home/cfr20/404/404-app-p02.htm. Tables 1, 2, and 3 list the rules by exertional level. POMS DI 25025.001 explains how SSA applies them.
Why does my GRID outcome differ from a coworker with the same condition?
GRID outcomes depend on the combination of age, education, RFC, and past work. Two people with the same diagnosis but different ages, education levels, or work histories can land in entirely different cells. The condition alone does not drive the outcome at Step 5.
