Quick answer: Do not let an AI résumé tool turn part-time work into full-time experience or guess a weekly schedule. For a U.S. federal résumé, verify actual weekly hours, employer, role, dates and duties from original records before submitting. The hiring agency—not an AI calculator—decides whether the experience meets a particular vacancy’s qualifications.
Scope: For U.S. federal job applications; not a private-sector résumé rule, an eligibility ruling or legal advice. A specific announcement can impose additional documentation and qualification conditions.
Why hours per week matter
USAJOBS résumé guidance asks applicants to list their employer, title, month-and-year dates, number of hours per week, and work relevant to the vacancy (plus series and grade for federal positions). Current general guidance limits federal résumés to two pages. OPM qualification policies explain that part-time work is prorated when crediting experience. Calendar time alone is not always equal to credited experience.
The five-field HOURS evidence card
1. Employer and role: Check an offer letter or personnel record. Do not substitute a client name for the actual employer. 2. Month/year dates: Compare pay periods and any gaps. 3. Hours/week: Check timesheets, schedules or payroll records, including schedule changes. 4. Relevant duties: Use only tasks you actually performed, with individual contributions clearly separated from team output. 5. Evidence range: Note which records and dates support the claimed hours, without pasting private identifiers or confidential timecards into AI.
Original teaching calculation: calendar months are not automatically credited months
Fictional case A: A hypothetical applicant worked 20 hours per week for 12 months. Against a 40-hour reference week, 20 ÷ 40 × 12 = 6 full-time-equivalent months. This corresponds to OPM’s published part-time example, but does not prove eligibility for any job. Fictional case B: Another hypothetical applicant worked a documented 30 hours weekly for 12 months. The same illustrative arithmetic gives 30 ÷ 40 × 12 = 9 full-time-equivalent months. Final credit depends on the governing qualification standard, documented duties and agency evaluation. Neither fictional figure belongs on a real application.
Variable-hours exception: Four illustrative weeks with 10, 30, 20 and 20 hours have a mean of (10 + 30 + 20 + 20) ÷ 4 = 20 hours/week for those four weeks only. It does not establish a yearlong schedule. Break genuinely different work periods into supported date ranges or request clarification about the agency’s required format.
Correcting three tempting AI overstatements
| Unsupported AI draft | Conditional evidence-based wording | Check first |
|---|---|---|
| “Full-time analyst, January–December 2025.” | “Part-time analyst, January–December 2025; 20 hours/week.” | Actual payroll schedule and dates |
| “One year of specialized federal experience.” | “Performed [documented duties] for 12 calendar months at 20 hours/week.” | Relevant duties; agency makes qualification decision |
| “Worked 40 hours/week” after one busy month | “20 hours/week January–August; 30 hours/week September–December.” | Separate schedules supported by records |
All three entries are fictional writing examples. Use the suggested wording only when your own records substantiate every detail. Do not use private employer documents without authorization.
Six checks before you submit
- Copy each AI-written employment claim to a private evidence checklist.
- Check employer, job title, dates and tasks against source records.
- Verify weekly hours and separate periods when the schedule changed.
- Recalculate averages only for the time spans actually documented.
- Compare the vacancy’s Qualifications, How You Will Be Evaluated and Required Documents sections.
- Correct or remove unsupported claims and retain a dated private evidence note.
A privacy-safe AI review prompt
Review this FICTIONAL U.S. federal résumé entry for inconsistencies. List employer, role, month/year dates, hours per week, supporting record, uncertainty and a modest rewrite. Do not infer full-time status, overtime, missing dates, agency qualification credit or hiring outcomes. Treat unverified details as UNVERIFIED. Never request actual SSNs, payroll records or private IDs. Fictional entry: [INSERT FAKE DATA].
Method, limitations and primary sources
Editorial source comparison, November 2, 2026: We compared the published USAJOBS résumé instructions with OPM’s General Schedule qualification policies and independently reproduced the arithmetic using invented inputs. We did not test a commercial AI product, review private employment records, interview an applicant or obtain an agency qualification decision. USAJOBS source; OPM source.
