Federal Clerical Tests & Office Support: OPM Series Guide

There is no single Federal Clerical Exam used for every office-support job in the U.S. government.

Federal clerical and assistance work is spread across multiple occupational series. The correct preparation path depends on the series, grade, vacancy announcement, and assessment invitation for the position you applied to.

This page is the broad federal clerical-support owner. It routes applicants to more specific pages when OPM defines a distinct occupation or proficiency requirement.

Practice material on this site is original educational content. It is not OPM, USA Hire, USAJOBS, or agency test content, and it does not reproduce live questions, scoring keys, or confidential assessment material.

Start with the occupational series

Federal clerical and office-support titles can sound similar while belonging to different OPM series.

Important examples include:

• 0303 Miscellaneous Clerk and Assistant — one-grade-interval clerical or assistant work for which no more specific series is appropriate;
• 0318 Secretary — secretary work covered by its own series;
• 0322 Clerk-Typist — clerk-typist work with a specific typing proficiency requirement;
• 0326 Office Automation Clerical and Assistance — clerical/assistant work requiring office-automation proficiency;
• 0356 Data Transcriber — data-transcription work with specific proficiency requirements;
• 0986 Legal Assistance — legal-support work requiring specialized knowledge of legal processes and procedures.

Many other specialized clerical and assistance series also exist in HR, finance, security, records, telecommunications, and other occupational groups.

The job title alone is therefore not enough. Always confirm the occupational series in the announcement.

What is Miscellaneous Clerk and Assistant Series 0303?

OPM’s Series 0303 covers clerical, assistant, or technician work for which no other occupational series is appropriate.

It is a residual series, not a universal label for every office-support job.

OPM states that positions should be classified in a more specific series when the work requires specialized processes or subject matter covered elsewhere.

That is why this page should not pretend that one generic “administrative assistant” or “office assistant” exam represents all federal support hiring.

Is there one Federal Administrative Assistant Exam?

No.

“Administrative Assistant” is a job title used in many organizations, but federal classification depends on the actual duties and occupational series. Depending on the work, a vacancy could fall under 0303, Office Automation 0326, Secretary 0318, Management Clerical and Assistance 0344, a specialized assistance series, or another classification.

For that reason, this site consolidates the former generic Federal Administrative Assistant Assessment route into this federal clerical/support owner rather than maintaining a second page that implies a universal exam.

Is there one Federal Office Assistant Exam?

No.

“Office Assistant” is also a generic title rather than one single federal examination program.

Some office-support roles involve typing or office automation; others involve records, correspondence, data entry, reception, program support, or specialized clerical work. The announcement’s occupational series determines the correct federal framework.

The former generic Federal Office Assistant Exam route is therefore consolidated into this hub.

Current USA Hire coverage for federal clerical roles

OPM’s current USA Hire availability table shows broad but series-specific coverage. Examples include:

Series	Occupation	Current USA Hire coverage
0303	Miscellaneous Clerk and Assistant	Grades 3–10, Classic
0304	Information Receptionist	Grades 4–9, Classic / PATCO - Clerical
0305	Mail and File	Grades 3–9, Classic / PATCO - Clerical
0318	Secretary	Grades 3–10, Classic
0322	Clerk-Typist	Grades 4–9, PATCO - Clerical
0326	Office Automation Clerical and Assistance	Grades 3–9, Classic / PATCO - Clerical
0356	Data Transcriber	Grades 4–9, PATCO - Clerical
0986	Legal Assistance	Grades 4–15, Classic / PATCO - Technical

USA Hire availability does not mean every vacancy in those series uses USA Hire. Standard Assessments are available to agencies for eligible non-supervisory hiring; the live announcement and invitation determine whether they are actually used.

OPM proficiency requirements that matter

Some clerical occupations have explicit proficiency requirements in addition to experience or education.

OPM’s current General Schedule qualification standards state, among other things:

• Clerk-Typist GS-2/4 and positions titled (Typing) or (Office Automation): 40 words per minute typing speed;
• Office Automation Clerk/Assistant, any grade: 40 words per minute typing speed;
• Data Transcriber GS-2: alphanumeric data-transcribing skill or 20 words per minute typing speed for transcription duties;
• Data Transcriber GS-3/4: alphanumeric data-transcribing skill or 25 words per minute typing speed for transcription duties.

Applicants can meet applicable proficiency requirements through the mechanisms OPM permits, including performance tests, authorized proficiency certificates, or self-certification where allowed; agencies may verify self-certified proficiency.

Those rules are occupation-specific. They should not be generalized into one broad clerical exam.

Choose the correct specialist guide

Use the page that matches the role in your announcement:

• Federal Clerk-Typist Test — for Series 0322 and the 40-WPM typing requirement;
• Federal Data Entry / Data Transcriber Test — for Series 0356 and data-transcription proficiency;
• Federal Legal Assistant 0986 — for specialized legal-support work;
• USA Hire Assessment — when your invitation explicitly names USA Hire.

If your title is Administrative Assistant, Office Assistant, Program Assistant, Support Assistant, or another broad label, use the occupational series shown in the vacancy before choosing practice material.

What clerical skills may be useful to practise?

Only practise skill areas that match the actual vacancy or assessment invitation.

Transferable clerical preparation can include:

• following written instructions;
• comparing names, numbers, dates, and codes;
• filing and record-keeping logic;
• reading comprehension;
• grammar and written expression;
• basic arithmetic;
• information ordering;
• data accuracy;
• typing when the role requires it;
• office-automation tasks when the role requires them;
• confidentiality and professional judgment.

These are common office-support competencies, not a universal federal test blueprint.

Original federal clerical practice examples

These examples are fictional and original.

Question 1 — Applying a filing rule

Which record should come first?

A. Adams-12 B. 204-B C. Brown-02 D. Carter-11

Best answer: B

The rule places number-led records before letter-led records.

Question 2 — Comparing codes

Target code: HR-50218-C

Which entry is an exact match?

A. HR-50281-C B. HR-50218-C C. HR-50218-G D. HR-52018-C

Best answer: B

Every character matches.

Question 3 — Basic arithmetic

A unit processes 48 requests on Monday, 57 on Tuesday, and 45 on Wednesday. How many requests were processed in total?

A. Route it Wednesday morning. B. Hold it for one week. C. Delete it. D. Route it before noon Tuesday.

Best answer: A

The request arrived after noon, so next-business-morning routing is allowed.

Question 5 — Professional judgment

A. Ignore the error. B. Change the local file without telling anyone. C. Follow the correction procedure and notify the appropriate recipient if required. D. Delete the record entirely.

Best answer: C

Accurate records require documented correction procedures.

How to prepare for your federal clerical vacancy

1. Read the live job announcement.
2. Record the occupational series and grade.
3. Check for typing, office-automation, data-transcription, or other proficiency requirements.
4. Identify whether USA Hire or another assessment system is named.
5. Use OPM and the hiring agency as the authority for qualifications and test requirements.
6. Open the specialist guide when a specific occupation such as 0322, 0356, or 0986 applies.
7. Use third-party practice only after the actual skill requirements are clear.

Common mistakes

Avoid these errors:

• assuming every federal office-support vacancy uses one clerical exam;
• treating Administrative Assistant or Office Assistant as a single federal occupational series;
• ignoring the occupational series in the announcement;
• missing a required typing or data-transcription proficiency standard;
• assuming USA Hire availability means USA Hire is mandatory;
• using a commercial prep provider as the source of official federal qualification rules.
