TSA publishes a preparation manual “to help you prepare to take the TSA Writing Skills Assessment”, with a grammar review and practice questions.1 Its questions come in three formats, and every one of them has a “no correction is necessary” option.
Choose the correction the sentence needs
Choose the best revision, for example the spelling
Choose the order that makes the text work
The course drills put the marked part in square brackets; on this page and in the free test it is underlined, as in TSA’s manual. The course practices sentence order inside one paragraph; the manual also orders whole paragraphs.
A Supervisory TSO announcement from January 2026 invites all qualified candidates to the S-TAB: the Work Personality Index (WPI) and the Writing Skills Assessment (WSA); their scores make up 100% of the overall score.2 Entry-level officer announcements name a different test, the TSO Assessment Battery (TAB), a computer-based test to evaluate x-ray interpretation aptitude.4 So if you apply as a new officer, prepare for the TAB with our TSA test prep. If your invitation names the WSA, this page is for you. The course trains the writing skills, not the Work Personality Index.
Lesson B7 teaches the rules behind almost every writing question, with right and wrong pairs, worked examples and three timed tests of 25 questions. Every answer is explained.
TSA’s manual also tests spelling and word choice in underlined words.1 Two more lessons train them, plus reading, each with a video lesson, a written guide and three timed tests.
Learn the rule, see it on an example, then put it on the clock. Same steps in every lesson, so you always know what comes next.
Every lesson has a short video. In B7 it covers the question types and the core rules in under four minutes.
Every rule with right and wrong pairs, a worked example for each question format, then a recap.
Four drills inside the B7 guide and an ordering tool for paragraph questions.
Three timed tests per lesson, with a review that shows the right answer, your answer and the explanation.
Then three full practice exams in one sitting: five x-ray blocks, then 50 English questions in 60 minutes.
The review after each test shows the correct answer, the one you picked and why. The full exams in lesson B8 follow the format test-takers report for the older test, so they also train the x-ray part.
Time limits and the full-exam layout are our own practice format; TSA does not publish them. Results are practice scores, not TSA scores.
Free questions show you the format. Here’s what they usually leave out.
| Free practice | TSA QuickPass | |
|---|---|---|
| Clock | Often untimed | Every test and every full exam on the clock |
| Rules | An answer key | Five grammar rules, punctuation, capitals and spelling, with right and wrong pairs |
| Formats | One or two | Find the error, sentence correction, completion, paragraph order, vocabulary, reading |
| Why an answer is right | Often missing | An explanation for every answer |
| Full-length practice | Rarely | 3 full exams with x-ray blocks and 50 English questions |
| After the test | Nothing | Interview, medical evaluation, background check, until day one |
| Cost | $0 | $68 once, 90 days of access |
From lesson B8. Pick how much time you have and see the route.
You must schedule and complete the test within 21 days of the invitation, so two weeks of focused preparation usually fits.
With fewer days the planner in lesson B8 drops the second and third practice test of each lesson first, then full exams. It always keeps the daily words and a light last day.
21 lessons, each with a video lesson and a written guide: 8 for the older x-ray and English test, 8 for the TAB, and 5 for the steps after the test.
Applying as a new officer? These pages cover the TAB and the older officer test.
Yes. The practice test on this page is free, with no account and no email: 15 English questions in 10 minutes 30 seconds, 12 on writing (find the error, sentence correction, sentence completion, paragraph order) and 3 on vocabulary and spelling. You get your score by question type, the lesson to start with and an explanation for every answer. The questions come from the practice drills of our course; they are not TSA’s own items.
The Writing Skills Assessment (WSA) is a multiple-choice writing test. A TSA announcement for Supervisory Transportation Security Officer from January 2026 lists it as part of the S-TAB, together with the Work Personality Index (WPI); the scores of both make up the overall score used to rank candidates. TSA’s preparation manual for the WSA shows three question formats: choose the correction a sentence needs, choose the best revision of underlined words, and put paragraphs in order, each with a “no correction is necessary” option.
Not according to the current announcements. Entry-level Transportation Security Officer announcements name the TSO Assessment Battery (TAB), a computer-based test to evaluate x-ray interpretation aptitude, and require that you are proficient in English. The WSA appears in the Supervisory TSO announcement as part of the S-TAB. If you apply as a new officer, prepare for the TAB; our TSA test prep page covers it. An older announcement from 2018 described the officer test as one to confirm English language proficiency and evaluate x-ray interpretation aptitude, so always check your own invitation.
TSA’s manual says your score is based only on the number of questions you answer correctly, and you are not penalized for wrong answers. So answer every question: eliminate what you can, then pick. In the Supervisory TSO announcement, the WPI and WSA scores together account for 100% of the overall score used to rank candidates. Neither source gives a passing score.
TSA’s manual does not give the number of questions or a time limit for the assessment; it only suggests taking no more than 15 minutes for its own practice questions. Our free test and the course drills use about 45 seconds a writing question and 30 seconds a vocabulary question, our own practice pace.
In our own summary of the manual’s grammar review: sentence building and commas, verbs and verb forms, nouns and pronouns, adjectives and adverbs, conjunctions, shifts in tense, person and voice, sentence order within paragraphs, capitalization and punctuation. Lesson B7 of the course turns these into five grammar rules, the punctuation and capitalization rules and four drill formats.
Read the whole sentence, find what is wrong in it, then put each option into the sentence and keep the one that fixes everything without adding a new error. “No correction necessary” is right only when the original has no error. Lesson B7 shows this on worked examples, and its three timed tests have 25 questions each.
No. The WPI is the second part of the S-TAB in the Supervisory TSO announcement, and the course does not prepare for it. The course covers the writing skills of the WSA in lesson B7, spelling and vocabulary in B6 and reading in B5.
The Supervisory TSO announcement says the WPI and WSA must be scheduled and completed at a proctored testing facility within 21 calendar days of the invitation, and that a failed S-TAB within the six months before the closing date makes you ineligible. TSA tests are scheduled through Pearson VUE with the access link in your invitation, and you bring a valid US-issued ID.
