The Six-Part FERS Disability Retirement Test, in Plain English (A Self-Audit, Not a Verdict)

If you’ve started researching FERS disability retirement, you’ve probably noticed how much of the advice online quietly answers a different question than the one you asked. You want to know whether you can apply. A lot of what you find is really about how sick you are. Those aren’t the same thing — and understanding the difference is the first, most useful step you can take.

Why “how sick am I?” is the wrong question

OPM doesn’t evaluate suffering. It evaluates whether a specific set of procedural conditions is met, and whether your file documents each one. A person with a serious diagnosis can be denied on a technicality; a person with a less dramatic condition can qualify because their record cleanly answers every question the rules ask. The rules live primarily in 5 C.F.R. Part 844 (§§ 844.102–844.103 and 844.201), and OPM restates them in plain language in its Types of Retirement guidance and in the pamphlet that ships with the forms (SF 3112-2).

The six requirements, one at a time

1. Eighteen months of creditable FERS civilian service. You must have completed at least 18 months of federal civilian service creditable under FERS (5 CFR § 844.103). Military time and certain other service can raise complex crediting questions — worth mapping carefully before you assume it counts.
2. A condition that prevents useful and efficient service in your current position. The inquiry is about your specific position, not every job on earth. It usually shows up as a deficiency in performance, conduct, or attendance — or a condition that is incompatible with useful and efficient service or with keeping the position (5 CFR §§ 844.102–844.103).
3. A condition expected to last at least one year. This is a prognosis about the future, not a requirement that you’ve already been disabled for twelve months. The distinction matters more than almost any other point on this list — see “the two clocks” below.
4. Your agency can’t accommodate you — and has considered reassignment. Your agency must certify that it cannot accommodate your condition in your present position and that it considered you for any vacant position at the same grade or pay level, in the same commuting area, for which you’re qualified (5 CFR § 844.103). This is documented on the agency’s portion of the SF 3112 package.
5. You apply on time. You must apply before separation or within one year after — and the application has to be received by OPM or your former agency within that year (5 CFR § 844.201). This is a hard deadline, not a guideline.
6. You also apply for Social Security disability. A FERS disability application requires you to apply for Social Security disability benefits (OPM SF 3112-2). Note the verb: apply. Approval by SSA is a separate question from this requirement.

The two clocks people confuse

Requirement #3 and requirement #5 both mention a year, and that coincidence causes real damage. One is a medical prognosis (the condition is expected to last at least a year). The other is a filing deadline (apply within a year of separation). People sometimes “wait a year to qualify,” not realizing they’re burning down the deadline clock at the same time. If you take one thing from this article, let it be that these are two different clocks running at once.

What this checklist can — and can’t — tell you

A self-audit can tell you which boxes your file clearly addresses and which ones are thin or missing. It cannot tell you that you “qualify” — only OPM decides that, based on the full record. Anyone promising you an outcome is telling you something the rules don’t allow them to know. The goal here is readiness: a file that answers each of the six questions in an organized, consistent way.

A five-minute self-audit

● Can I show at least 18 months of FERS-creditable civilian service?

● Does my record connect my condition to the actual duties of my current position?

● Does a provider state, in writing, that my condition is expected to last at least a year?

● Has the accommodation/reassignment question actually been answered on paper?

● Do I know my filing deadline — and can I prove timely receipt?

● Have I applied for SSDI (if under 62) and kept the confirmation?

Where TFDR fits (and where it doesn’t)

The Federal Disability Review helps you get administratively ready: understanding these requirements, organizing your own records, and reviewing the documents you prepare so the six boxes are clearly and consistently addressed. We do not draft your application, represent you before OPM, or handle reconsideration and MSPB appeals — those are attorney matters, and we’ll say so plainly. If you’d like a second set of eyes on your own physician’s statement and SF-3112 forms, our Document Review is built for exactly that; if you’re earlier in the process, a Strategy Consult is a good starting point.
