Job duties and functional impact workbook
Turn general descriptions of difficulty into specific, sourced examples tied to your position.
Reviewed October 14, 2026 · About 45 minutes to read
Create a factual duty-and-impact worksheet you can use with your physician, HR, and applicant statement.
Start with the real position
A useful worksheet explains your work before it explains your limitations. Gather your official position description, performance standards, and relevant work instructions. Your SF-50 can confirm the position title, series, and grade, but it is not a complete duty description. If a position description is outdated, retain it and separately describe the actual assigned work, identifying the source and period. Ask your supervisor or HR to clarify discrepancies rather than silently rewriting the official document.
This is a preparation workbook, not a vocational evaluation or medical assessment. It cannot establish eligibility by itself. Its value is traceability: another reader can see which duty came from an agency record, which restriction came from a medical source, and which experience you reported.
Break the job into observable demands
- Choose five to eight important duties. Begin with critical or essential elements rather than every small task.
- Describe how each duty is performed: location, equipment, pace, concentration, interaction, lifting, travel, or attendance requirements. Include frequency and duration when you know them.
- Identify the required result or standard. For example, distinguish reading occasional messages from reviewing time-sensitive technical material throughout a shift.
- Record the source and date for the duty and standard. If the estimate is yours, label it as your estimate.
Complete these prompts privately in your downloaded workbook or on paper. Nothing here is submitted or saved.
Keep three kinds of information separate
Use separate columns for agency duties, clinician-documented restrictions, and your own observations. A symptom you report may be important even before a clinician documents a corresponding restriction. Label it honestly instead of turning it into a medical instruction. A limitation documented for one treatment period should not automatically be described as permanent or current.
| Information | Suitable wording | Source |
|---|---|---|
| Agency duty | Conduct scheduled interviews and document results | Position description, dated copy |
| Medical restriction | Restriction described in signed treatment note | Clinician, note date and page |
| Your observation | I stopped twice during the interview because symptoms increased | Your dated account; not a medical conclusion |
Explain the practical connection without pretending to settle a medical question. “The restriction and task appear to overlap; I need the clinician to clarify” is more accurate than an unsupported conclusion that a duty is impossible. Preserve the clinician’s qualifications and time limits when summarizing a restriction.
Describe what changed and what helped
For each difficulty, record when it began, a typical occurrence, and a concrete consequence. Include successful adaptations and remaining problems. Reliable performance, attendance, and conduct are relevant, but a person does not have to deliberately perform poorly to create evidence. FERS regulations also address a disabling condition incompatible with useful and efficient service or retention even without a demonstrated service deficiency.
- Describe a representative day and a flare separately. Avoid presenting the single worst day as every day.
- When using leave totals, identify the reporting period and source. Do not assume every absence was caused by the condition at issue.
- Document temporary help, changed assignments, reduced hours, or coworker coverage so performance records have context.
- Explain accommodation results honestly: what improved, what did not, and how long the arrangement operated.

Complete one row at a time. Where a fact is missing, write “not yet obtained” and add a next action. A blank with a plan is better than a confident assumption. Keep documents in a separate evidence folder and use file references in the worksheet so you can retrieve the original quickly.
