ATI TEAS study guide: what the official manual covers
The official ATI TEAS Study Guide 2026-2027 costs US$19.99 (eBook) or US$24.99 (print) and covers all four sections with one 150-question test.
Short answer: The Official ATI TEAS Study Guide 2026-2027 costs US$19.99 as an eBook or US$24.99 in print, and it reviews all four TEAS sections with key terms, unit quizzes and one 150-question practice test. It is a content review rather than a complete prep plan, so ATI itself suggests pairing it with timed online practice tests that show your weak areas.
Assessment Technologies Institute (ATI) writes the TEAS (Test of Essential Academic Skills) and publishes this guide. Facts below come from ATI's pages, read on November 15, 2026. ATI's prep products are final sale, with no returns or refunds.
What the manual includes and costs
| Item | eBook | Printed book |
|---|---|---|
| Price | US$19.99 | US$24.99 |
| How you get it | Read online in your ATI account | Shipped by FedEx, usually 3 to 4 business days |
| How long it lasts | 4 years from purchase | Does not expire |
| Download | Not available | Not applicable |
| Practice test | Online, scored automatically, with a score report | Printed in the book with an answer key; paper only |
| Corrections | Made directly in the eBook | Listed in a separate addendum |
ATI's TEAS prep page says the guide covers 4 subject areas, key terms, exam tips and 325 end-of-section quiz questions. The full-length practice test has 150 questions with explanations for right and wrong answers. ATI calls it Form C, and it is different from ATI's online Practice Tests A and B.
The printed book and the eBook are separate products. Buying the print edition does not give you the eBook.
What is inside, part by part
ATI lists this table of contents for the 2026-2027 edition:
| Part | Content | Pages |
|---|---|---|
| 1 | Introduction: what to expect, test resources, preparation strategies | Front section |
| 2 | Reading: key ideas and details, craft and structure, integration of knowledge and ideas | 1 to 88 |
| 3 | Math: numbers and algebra, measurement and data | 89 to 162 |
| 4 | Science: anatomy and physiology, life and physical sciences, chemistry, scientific reasoning | 163 to 294 |
| 5 | English and language usage: conventions, knowledge of language, vocabulary | 295 to 346 |
| 6 | Comprehensive practice test with answer key | 347 to 396 |
| Index | 397 to 414 |
Each subject part ends with key terms and a unit quiz. The science part is the longest, which matches the exam: science has 50 of the 170 TEAS questions. For each section's details, see TEAS reading, TEAS math, TEAS science and TEAS English.
What it lacks
The guide is strong on content. Based on ATI's own product pages, it does not give you:
- Online scoring with the print edition. The printed practice test is on paper. You score it yourself with the answer key, and there is no automatic report of your weak topics.
- An adaptive study plan. ATI's adaptive lessons are in SmartPrep, a separate product.
- More than one full-length test. The guide has one. ATI sells Practice Tests A and B separately at US$29.99 each.
- A download. The eBook is read online only.
A single timed test is not enough to measure progress, because you need a second test to see if your study worked. That is the main reason to add practice tests.
A plan to pair it with practice tests
ATI recommends at least six weeks of TEAS study. A simple way to use the guide inside that time:
- Week 1: baseline. Take a timed practice test first. ATI's free 60-question online test costs nothing, or use Practice Test A. Note your weakest sections.
- Weeks 2 to 5: study by section. Read the guide part for your weakest section first, then the next. Do each unit quiz at the end of the part.
- Middle of the plan: check progress. Take a second full-length test, such as Practice Test B, and adjust.
- Week 6: rehearsal. Take the guide's own 150-question test, timed and in one sitting, then review every explanation.
ATI's paid tests are compared in ATI TEAS practice tests, and free options from other companies are in free TEAS practice tests. The full calendar is in our TEAS study schedule.
Older editions and the addendum
ATI says the basic concepts have not changed, but older guides have a different spread of questions and lack the newer alternate item types. Only the newest eBook is sold. If you study from an older print copy, ATI recommends downloading the past addenda.
For the 2026-2027 printed guide, ATI's addendum listed one correction as of February 6, 2026: the axis labels on a graph on page 116 in the math part. Later printings already include the fix.
What to do next
- Decide between eBook and print. Choose the eBook if you want the practice test scored online.
- Take a baseline practice test before you open the guide.
- Plan at least one more full-length practice test for the middle of your study period.
Common questions
Is the study guide enough on its own?
It covers the content, but it gives you only one full-length test. ATI suggests adding its online Practice Tests A and B to find your weak areas.
Does the guide come with the exam fee?
No. ATI says study materials are bought separately from the US$120 exam registration.
Can I use a guide from a friend?
You can, but ATI says older editions do not match the current spread of questions or the newer question types. Check the addendum for your edition.
