If you are applying to a nursing or allied health program, you have likely encountered the TEAS exam — the Test of Essential Academic Skills. It is a standardized admissions assessment that measures academic readiness rather than clinical skill, which means the material you need to know is drawn from foundational subjects: reading comprehension, mathematics, science, and English language usage.
This guide walks through the key topics covered in each section, explains what each section is really testing, and outlines a study approach that prioritizes understanding over memorization. By the end, you should have a clear picture of what to review first, how to structure your preparation, and how to walk into the testing center feeling prepared rather than panicked.
What the TEAS Exam Measures
The TEAS assesses the academic building blocks that health science students rely on throughout their training. Reading comprehension supports understanding of textbooks and care documentation. Math underpins dosage calculation and data interpretation. Science provides the foundation for anatomy, physiology, and pharmacology coursework. English language usage affects how clearly you communicate in written records and professional settings.
Results are typically reported as a total score plus subscale scores for each section, so a strong performance in one area does not fully compensate for a weak one. Many programs set minimum score requirements, and those thresholds vary widely. Always confirm the specific requirements and accepted formats with the programs you are applying to, since policies and test structures can change over time.
The Four Sections at a Glance
- Reading — passages followed by questions on main ideas, details, structure, and author intent.
- Mathematics — arithmetic, algebra, measurement, and interpretation of charts and graphs.
- Science — human anatomy and physiology (the largest portion), life and physical sciences, and scientific reasoning.
- English and Language Usage — grammar, punctuation, sentence structure, and vocabulary.
The exam is multiple choice, delivered on a computer, and includes a small number of unscored trial questions mixed in with the scored ones. Because the sections are timed individually, pacing matters as much as knowledge.
Reading: Comprehension Under Time Pressure
Reading questions test whether you can extract meaning from a passage quickly and accurately. Most items fall into three broad categories.
Key Ideas and Details
You will be asked to identify the main idea, locate supporting details, summarize a passage, and draw straightforward conclusions. The skill here is distinguishing the central point from illustrative examples.
Craft and Structure
These questions focus on word choice, the author’s purpose, tone, and how a passage is organized. Recognizing whether a passage is comparing, sequencing, or arguing helps you predict the correct answer.
Integration of Knowledge and Ideas
Here you evaluate arguments, distinguish fact from opinion, and compare how two passages treat the same subject. Practice reading short informational articles and summarizing them in one sentence — this habit trains exactly the skill being tested.
Mathematics: Practical, Applied Arithmetic
The math section is not abstract. It emphasizes the kinds of calculations that appear in health science coursework and everyday clinical settings.
Numbers and Operations
Expect fractions, decimals, percentages, ratios, proportions, order of operations, and conversions between fractions, decimals, and percentages. Ratio and proportion problems are especially common and directly relevant to dosage-style calculations.
Algebra and Equations
You should be comfortable solving one-variable equations, working with inequalities, translating word problems into expressions, and interpreting simple formulas. Many of these have a real-world framing rather than a purely symbolic one.
Measurement and Data
This includes unit conversions within the metric system, reading tables, bar graphs, line graphs, and pie charts, and calculating basic statistics such as mean, median, mode, and range. Being able to move fluidly between metric units is worth prioritizing.
Science: The Largest and Most Detailed Section
Science carries the most questions and the most content. It rewards students who understand systems and relationships rather than isolated facts.
Human Anatomy and Physiology
This is the dominant topic. Expect questions on the structure and function of major body systems, including:
- Cardiovascular system — heart chambers, blood flow, circulation
- Respiratory system — gas exchange and airway anatomy
- Nervous system — neurons, brain regions, reflex pathways
- Digestive system — organs, enzymes, nutrient absorption
- Musculoskeletal system — bone structure, muscle types, movement
- Endocrine system — hormones and their targets
- Urinary, reproductive, integumentary, and immune systems
Focus on function as much as naming. Questions often ask what happens when a process is disrupted, which requires understanding rather than recall.
Life and Physical Sciences
This covers basic biology concepts such as cell structure, mitosis, genetics, and macromolecules, along with foundational chemistry and physics — atomic structure, chemical bonds, states of matter, pH, and simple motion or energy principles.
Scientific Reasoning
Some items ask you to interpret an experiment, identify variables, evaluate whether a conclusion is supported by data, or recognize a flawed study design. Reading the setup carefully usually matters more than prior knowledge here.
English and Language Usage: Precision in Communication
Conventions of Standard English
Punctuation, subject-verb agreement, pronoun usage, capitalization, and sentence structure. These questions reward attention to detail rather than speed.
Knowledge of Language
You may be asked to choose the most concise or clear way to express an idea, or to correct a sentence that is grammatically valid but awkward or ambiguous.
Vocabulary Acquisition
Expect questions based on context clues, word roots, prefixes and suffixes, and commonly confused word pairs. Learning common roots and prefixes gives you leverage on words you have never seen.
Building a Study Plan That Works
- Take a practice test first. A baseline score tells you where to spend time instead of guessing.
- Rank your sections by weakness, not preference. Study the areas with the largest gap first, while you have the most energy and time.
- Block your calendar. Short, consistent sessions several times a week beat marathon cramming.
- Use active recall. Quiz yourself, write summaries from memory, and explain concepts aloud rather than rereading notes.
- Practice timed sets. Accuracy without pacing will not help you on test day.
- Review every wrong answer. Ask why the correct one is right and why yours was not — that gap is where learning happens.
For the science section in particular, drawing diagrams of body systems from memory is one of the most efficient study techniques available.
Test-Day Tips
- Confirm your appointment time, identification requirements, and testing location in advance.
- Get a full night’s sleep — reaction time and reading comprehension both suffer with fatigue.
- Eat a normal meal beforehand rather than experimenting with something new.
- Answer every question. There is no penalty for guessing, so never leave a blank.
- Flag difficult items and return to them if time allows, but do not let one question consume your section.
- Use the on-screen calculator only where permitted, and double-check units in math problems.
Key Takeaways
The TEAS exam rewards foundational knowledge in four predictable areas: reading comprehension, applied mathematics, science with a heavy emphasis on human anatomy and physiology, and standard English usage. Success comes less from memorizing trivia and more from understanding how systems, sentences, and numbers work together — then practicing under realistic time constraints.
A steady, structured study plan built around a baseline practice test, active recall, and careful review of mistakes will serve you better than any last-minute cramming. If you are preparing for a career in health care, that same disciplined approach will carry you through your program and beyond.
