Start with the free official material
Before buying a book, collect the three free things ATI itself publishes. Together they tell you what is tested, how it is weighted and where you stand today.
- The ATI TEAS Version 7 content outline. This free PDF from ATI lists every objective that may be assessed, section by section, with the number of scored questions for each sub-area. It ends with 8 sample questions, two per section, with the answers.
- The free online practice test. According to ATI Help, it has 60 questions, 15 in each section, includes alternate item types such as select all that apply and fill in the blank, and gives rationales for right and wrong answers plus a score report. You add it to an ATI account at a $0.00 checkout, and attempts are unlimited, but it is always the same set of questions.
- ATI's preparation advice. ATI recommends allowing at least 6 weeks of preparation, and its five-step method is: learn the content areas, take the free test as a baseline, pick your materials, build a timeline that starts with your weakest subjects, and practice under timed conditions.
The exam format itself (170 questions, four timed sections, fees, ID) is on our free TEAS practice test page. This guide is only about how to study.
Where the points are
The content outline gives the weight of each area in scored questions. Use it to split your time: the more questions, the more hours.
| Section | Scored questions | Share of the test | Sub-areas (scored questions) |
|---|---|---|---|
| Science | 44 | 29% | Anatomy and physiology 18, biology 9, chemistry 8, scientific reasoning 9 |
| Reading | 39 | 26% | Key ideas and details 15, craft and structure 9, integration of knowledge and ideas 15 |
| Math | 34 | 23% | Number and algebra 18, measurement and data 16 |
| English and Language Usage | 33 | 22% | Conventions of standard English 12, knowledge of language 11, vocabulary 10 |
Figures from the ATI content outline. One sub-area stands out: anatomy and physiology alone carries 18 scored questions, as many as all of number and algebra, and more than biology and chemistry together.
What to study in each section
Each list below follows the objectives in the content outline, in plain words.
Science
- Anatomy and physiology: general orientation of the body (planes, directions, regions), then the systems the outline names one by one: respiratory, cardiovascular, digestive, nervous, muscular, reproductive, integumentary, endocrine, urinary, immune and skeletal. Learn structure and function together: what the organ is, where it is, what it does.
- Biology: cell structure and organization, how DNA relates to protein structure, Mendel's laws of inheritance, the basic macromolecules, and the role of microorganisms in disease.
- Chemistry: atomic structure, physical properties and changes of matter, chemical reactions and the conditions that affect them, solutions, acids and bases.
- Scientific reasoning: measurement tools and units, using evidence and logic, predicting relationships, and interpreting an investigation with the scientific method.
A free, open textbook such as OpenStax Anatomy and Physiology 2e covers every system on the list; it is not written for the TEAS, so use the outline to decide which chapters to read. Practice with our TEAS science questions.
Reading
- Key ideas and details: summarize a multi-paragraph text, draw inferences, follow written directions, find specific information, read charts and graphs, and put events in sequence.
- Craft and structure: fact versus opinion, word meaning from context, the author's purpose and point of view.
- Integration of knowledge and ideas: use evidence to predict and conclude, compare themes across texts, evaluate an argument, and combine data from several sources and formats.
Reading improves with volume. Read short nonfiction every day and, after each piece, say its main idea in one sentence. Then try our TEAS reading questions.
Math
- Number and algebra: convert between fractions, decimals and percentages, operate with and order rational numbers, solve one-variable equations, and solve real-world problems with percentages, proportions, ratios, rates, estimation and inequalities.
- Measurement and data: read tables, charts and graphs, use basic statistics, describe the relationship between two variables, calculate geometric quantities, and convert within and between standard and metric units.
Only a basic on-screen calculator is available on the real exam, not a scientific or graphing one. It is available in every section, and ATI suggests trying it on the free practice test so it is not new on exam day. Our TEAS math questions show every step.
English and Language Usage
- Conventions of standard English: spelling, punctuation and sentence structure.
- Knowledge of language: grammar for clarity, language suited to the audience, and building a well-organized paragraph.
- Vocabulary: the writing process and word meaning from word parts (roots, prefixes, suffixes).
A short list of common roots and prefixes pays off twice, in vocabulary and in reading. Test yourself with our TEAS English questions.
A six-week plan
This schedule fits ATI's six-week recommendation and puts the heavier sections first. Adjust it to your baseline: if the free test shows math is your weakest area, swap weeks.
| Week | Main focus | Also |
|---|---|---|
| 1 | Take the free ATI practice test; read the content outline; start anatomy and physiology (orientation, skeletal, muscular, integumentary) | List every wrong answer by sub-area |
| 2 | Anatomy and physiology (cardiovascular, respiratory, digestive, urinary, nervous, endocrine, immune, reproductive) | 20 minutes of reading practice a day |
| 3 | Biology, chemistry and scientific reasoning | Math: fractions, decimals, percentages |
| 4 | Math: equations, ratios and proportions, unit conversions, data and geometry | English: punctuation and sentence structure |
| 5 | Reading: all three sub-areas under time; English: grammar, paragraphs, word parts | First full timed practice test |
| 6 | Review your error list only; second full timed practice test | Light review the last two days |
Time full sections, not single questions. ATI's timing page works out about 1.2 minutes per question in reading and science, 1.5 in math and 1 in English, and says there is no penalty for guessing, so practice answering every question.
How to review a practice test
The step most people skip is the review. ATI's advice is to read the rationales for every question you missed, and for the ones you guessed right. For each miss, write one line: the sub-area, the reason (did not know it, misread it, ran out of time) and the rule you will use next time. After two or three tests, the pattern tells you what to study in the final week.
If you want to buy official material
ATI sells its own prep products: the SmartPrep adaptive tutorial, online practice tests (Form A and Form B, with different questions), a mobile app with a free version, flashcards and bundles. The current book is the ATI TEAS Study Guide 2026-2027, sold at $19.99 as an eBook (four years of access) or $24.99 in print. ATI says it covers the four subject areas with end-of-chapter quizzes and includes a 150-question full-length practice test (Form C) with answer explanations.
None of this is required. You can prepare with the free outline, the free practice test and free textbooks, and decide later whether one paid practice test is worth it to check your timing near the end.
After the test
If you need a retake, ATI says your score report includes a Focused Review that points you to the topics you missed. What counts as a good result depends on your program, which is covered in our guide to TEAS scores. Our practice questions are original, written from ATI's published outline; they are not ATI questions and cannot predict your official score.
