Federal Air Marshal Test: FAB Study Guide and Practice
Last updated: July 25, 2026 | Sources: TSA.gov & USAJOBS.gov
The Federal Air Marshal Assessment Battery, or FAB, is one major gate in the Federal Air Marshal hiring process. TSA’s official preparation manual identifies three components: Logic-Based Reasoning, Writing, and Video-Based Situational Judgment. Together they measure whether you can interpret complex written information, apply rules without unsupported assumptions, recognize correct written English, evaluate professional workplace responses, absorb visual details, and make sound judgments under pressure.
The FAB is not the TSO Assessment Battery. It does not test X-ray image interpretation, passenger-screening procedures, firearms knowledge, federal criminal law, or classified FAM tactics. You are not expected to possess protected operational knowledge before training.
TSA does not publicly guarantee one universal FAB question count, test duration, passing percentage, or score-reporting schedule. Follow your assessment invitation rather than an unofficial number.

Where the FAB Fits
You generally take the FAB after finding an open announcement, submitting a USAJOBS application with the required resume and documents, meeting initial eligibility and qualification requirements, and receiving an official assessment invitation. Do not attempt to schedule the FAB through an unofficial testing company. Use only TSA or authorized administrator instructions.
Passing the FAB does not guarantee an interview, conditional offer, clearance, or appointment. It indicates only that you achieved the result required to continue under the applicable assessment process. The wider path is covered in the Federal Air Marshal career guide.
Logic-Based Reasoning
This section evaluates careful reading, rule application, and valid deduction. Problems can require sequencing people or events, assigning people or objects to groups, applying positive and negative rules, identifying what must be true or cannot be true, and determining whether information is insufficient. Accept the scenario’s facts as written. Do not add outside knowledge from real TSA policy, military experience, or common sense that is not in the problem.
Choose True only when a conclusion must follow, False when it conflicts with the facts, and Cannot Be Determined when the facts leave both possibilities open. A possible conclusion is not automatically true. Watch keywords such as only, unless, exactly, at least, and at most. Draw a simple diagram, place the strongest rules first, and test answer choices carefully. “Could be true” and “must be true” require different proof.
Original Logic Practice Question
This practice question is original. It is not taken from the official FAB.
Four employees—J, K, L, and M—must deliver presentations from first through fourth. J presents before L. K cannot present first. M presents immediately after K. Which employee must present first?
A. J
B. K
C. L
D. M
Answer: A. J. K cannot present first, and M must immediately follow K, so M cannot present first. L cannot present first because J must appear before L. Therefore J must present first.
More logic practice and method detail are in the Federal Air Marshal logic-test guide.
Writing Test
The Writing Test evaluates recognition of effective written English: grammar, syntax, word usage, sentence structure, punctuation, and organization. It is not generally described as a creative-writing assessment. Review subject-verb agreement, pronoun clarity, verb tense, fragments, run-ons, misplaced modifiers, parallel structure, and commonly confused words. Prefer the clearest grammatically correct option over the longest or most formal-sounding sentence.
Original Writing Practice Question
This practice question is original. It is not an official FAB item.
Choose the best sentence.
A. The officers assignment changed, however he reported on time.
B. The officer’s assignment changed; however, he reported on time.
C. The officers’ assignment changed however he reported, on time.
D. The officer’s assignment changed however; he reported on time.
Correct answer: B. Singular possession and a semicolon before “however” correctly join two independent clauses.
See the Federal Air Marshal writing-test guide for additional editing practice.
Video-Based Situational Judgment
The SJT presents job-related videos and asks you to evaluate response effectiveness. It can also include observation questions about people, clothing, objects, locations, sequence, and movement. Relevant competencies include judgment, integrity, communication, teamwork, conflict management, safety awareness, proportional response, and professionalism.
A strong response generally identifies the real problem, protects immediate safety, stays within authority, communicates professionally, escalates proportionately, and documents significant matters when required. The most aggressive option is not automatically best. Dishonesty, retaliation, and acting outside authority are weak responses. According to TSA’s manual, you cannot return to a previous Situational Judgment item after advancing, so confirm your selection before moving on.
Original SJT Practice Scenario
This scenario is original practice only.
A coworker becomes visibly frustrated with a traveler and begins speaking in an unprofessional tone. The situation is not yet physically dangerous. The most appropriate response is to calmly intervene within your role, help stabilize the interaction, and notify the appropriate supervisor. Publicly insulting the coworker, ignoring the issue, or immediately using physical force are not proportionate.
More guidance is in the situational-judgment and observation guides.
Test Rules, Scoring, and Retakes
TSA’s official manual states that the score is based on correct responses and that incorrect answers are not penalized, so answer every question. Use elimination and careful reading rather than random guessing or answer-letter patterns. Candidates can review Logic and Writing answers when time remains. Do not create another USAJOBS or Login.gov identity to bypass a result. Retest eligibility depends on the official result, current policy, and instructions associated with a future vacancy.
Begin with TSA’s free FAB preparation manual. Complete official examples, identify weak sections, add targeted practice, then use timed mixed exercises and review every error. Protect assessment security and follow invitation logistics for platform, location, identification, and accessibility arrangements.
Common Mistakes
Candidates often prepare with TSO materials, memorize alleged live questions, add outside knowledge to logic scenarios, select the most aggressive SJT response, advance before confirming an SJT answer, leave questions blank, ignore observation details, or treat a FAB pass as a final job offer.
Frequently Asked Questions
What are the three FAB sections?
Logic-Based Reasoning, Writing, and Video-Based Situational Judgment.
Is the FAB the same as the TSO test?
No.
Is guessing penalized?
TSA’s manual states incorrect answers are not penalized and advises candidates to answer every question.
Does TSA publish a passing score?
TSA does not publish one universal passing percentage in its general preparation material.
Can I review answers?
Logic and Writing answers can be reviewed when time remains. Situational Judgment items cannot be revisited after advancing.
Does passing the FAB guarantee employment?
No. Physical, medical, polygraph, background, clearance, training, and selection stages can remain.
