The Role of Your Position Description in a Disability Retirement Claim
TFDR Editorial ·
Why Your Position Description Is Critical
In a FERS disability retirement claim, OPM does not evaluate whether you can work in general — they evaluate whether you can perform the specific duties of your position. The document that defines those duties is your official position description (PD). This makes your PD one of the most important documents in your entire application, yet it is one that many applicants overlook or fail to review for accuracy before filing.
How OPM Uses Your Position Description
When OPM reviews your disability retirement application, they compare your medical limitations (as documented in SF 3112C and supporting medical evidence) against the essential functions listed in your position description. The key question is: do your medical limitations prevent you from performing the "critical elements" or essential duties described in your PD?
If your PD describes duties that your condition clearly prevents you from performing, and your medical evidence specifically addresses those duties, your case is straightforward. If your PD is vague, outdated, or does not accurately reflect what you actually do, problems arise.
Common Position Description Problems
The PD Doesn't Match Your Actual Duties
This is the most common issue. Over time, your actual duties may have evolved significantly from what your PD describes. You may perform tasks that are more physically demanding, more cognitively complex, or more stressful than what the PD reflects. If OPM evaluates your claim against an inaccurate PD, they may conclude your condition does not prevent you from performing the described duties — even though it prevents you from performing your actual duties.
The PD Is Too Vague
Some position descriptions use broad, generic language that does not capture the specific physical, cognitive, or interpersonal demands of the job. A PD that says "performs administrative duties" does not convey the same demands as one that says "reviews and analyzes 50+ complex financial documents daily, requiring sustained concentration for 6-8 hours." The more specific your PD, the easier it is to connect your limitations to specific duties.
The PD Understates Physical or Cognitive Demands
Some PDs were written years ago when the position had different requirements. If your position now requires more standing, lifting, computer use, public interaction, or cognitive demand than the PD reflects, the document works against you.
What to Do If Your PD Is Inaccurate
Request a PD Review or Update
Before filing your disability retirement application, request that your supervisor and HR office review and update your position description to accurately reflect your current duties. This is a standard HR process — position descriptions should be reviewed periodically regardless of disability retirement. Frame your request as ensuring accuracy for classification purposes, not specifically for disability retirement.
Document the Discrepancy
If your agency refuses to update the PD, or if the update process will take too long, document the discrepancy in your SF 3112A (Applicant's Statement of Disability). Clearly describe what your actual duties are versus what the PD states. Provide specific examples of tasks you perform that are not reflected in the official PD.
Ask Your Supervisor to Address It
Your supervisor completes SF 3112B (Supervisor's Statement), which includes a description of your duties. If your supervisor accurately describes your actual duties — even if they differ from the PD — this provides OPM with a more complete picture. Encourage your supervisor to be thorough and specific in their description.
Connecting Your PD to Your Medical Evidence
The strongest disability retirement applications create a clear chain:
- Position Description defines specific duties and their demands
- Medical Evidence (SF 3112C) describes specific functional limitations
- Your Statement (SF 3112A) explains how those limitations prevent those specific duties
For this chain to work, your physician needs to see your position description. Provide your treating physician with a copy of your PD and ask them to specifically address how your condition prevents you from performing the duties described. Generic medical statements that don't reference your actual job duties are the number one reason claims are denied.
Critical Elements vs. Non-Critical Elements
Not every duty in your PD carries equal weight. "Critical elements" (sometimes called "essential functions") are the core duties that define the purpose of your position. OPM focuses on whether you can perform these critical elements. If your condition prevents you from performing one or more critical elements — even if you could still perform non-critical duties — you may qualify for disability retirement.
Your PD should identify which duties are critical elements. If it does not, your supervisor's statement (SF 3112B) should clarify which duties are considered essential to the position.
Grade Level and Complexity
Your PD also establishes the grade level and complexity of your position. This matters because OPM evaluates whether you can perform at the level required — not just whether you can perform similar duties at a lower level. A GS-13 analyst position requires different cognitive demands than a GS-5 clerical position, even if both involve "reviewing documents." Your medical evidence should address the complexity and cognitive demands appropriate to your grade level.
The Reassignment Factor
Remember that one requirement for disability retirement is that your agency cannot reassign you to a vacant position at the same grade and pay level. Your PD establishes what grade and pay level you currently occupy, which defines the universe of positions your agency must search for reassignment purposes. If no vacant positions at your grade exist that you could perform given your limitations, this requirement is met.
Key Takeaway
Your position description is the measuring stick OPM uses to evaluate your claim. Before filing, review your PD carefully, ensure it accurately reflects your actual duties, and provide it to your physician so they can specifically address how your condition prevents you from performing those duties. An accurate, detailed PD combined with medical evidence that directly references your specific job duties creates the strongest possible foundation for your disability retirement application.
