TEAS Science is the section that decides nursing school admission for many students. Half the test is anatomy and physiology, and the rest blends scientific reasoning, life science, and physical science. Most students who miss the cut on the TEAS lose those points in this section. The good news is that the TEAS Science domain rewards a small number of repeatable habits, not memorizing every textbook detail.
This guide walks through the seven highest yield TEAS Science topics for 2026, the strongest study sequence, and the kinds of stems that show up the most on the new TEAS 7 form. Pair this guide with the TEAS Test 2026 Study Guide for the full road map.
What TEAS Science actually tests in 2026
The 2026 TEAS Science section runs 50 scored items in 60 minutes. Anatomy and physiology accounts for roughly 32 to 36 of those items. Life and physical science makes up about 8 to 10. Scientific reasoning accounts for the rest. There is no penalty for wrong answers, so finish every item.
The most important shift in TEAS 7 is the move toward scenario style stems. A 2025 admissions cycle review by ATI showed that more than half of TEAS Science items now embed the question inside a clinical or laboratory mini scenario. Students who treat each item like a story problem outperform students who try to recognize the answer.
The seven topics that win the most points
1. The cardiovascular system. Map the path of blood from the right atrium through the lungs and back out the aorta, and learn the four valves in order. Most cardiovascular items can be solved by tracing the loop. Practice questions on the TEAS commonly hide the right answer behind a small order detail, like which vessel comes immediately after the pulmonary capillaries.
2. The respiratory system. Know the conducting versus respiratory zones, what alveoli do, and how oxygen and carbon dioxide cross the membrane. Items often pair this with the cardiovascular loop, so build them as a single unit when you study.
3. The nervous system. Memorize the four lobes of the brain, the function of the cerebellum, and the difference between sympathetic and parasympathetic responses. Two or three nervous system items appear on every form.
4. The digestive system. Trace the path from mouth to anus, name the accessory organs (liver, gallbladder, pancreas), and learn where the major nutrients are absorbed. The small intestine sections (duodenum, jejunum, ileum) are tested often.
5. The endocrine system. Pair each gland with its main hormone and the body system the hormone controls. The pituitary, thyroid, adrenal, and pancreas show up the most.
6. The skeletal and muscular systems. Know the difference between axial and appendicular bones, the three muscle types, and how a sliding filament cycle works at a high level.
7. Scientific reasoning. Practice reading a results table or a graph and choosing the conclusion that the data support. The TEAS rewards conservative claims. If a stem says a study had only 30 participants, the right answer almost always avoids the word always.
A four week TEAS Science study sequence
Week 1: Anatomy systems block one. Cardiovascular, respiratory, nervous. Spend 60 minutes a day. Use a labeled diagram, then close the book and redraw it from memory before any practice questions.
Week 2: Anatomy systems block two. Digestive, endocrine, skeletal, muscular. Same 60 minute pattern. After each system, do 10 timed practice questions to lock in the recall.
Week 3: Life and physical science. Cells, genetics, chemical bonds, states of matter, and basic physics like motion and energy. This is where many students underprepare. Two short sessions a day beats one long session.
Week 4: Scientific reasoning and full length practice. Take one full length TEAS practice test under real time pressure, then review every missed item using the rationale, the analogies, and the recommended review article. Repeat with a second full length test 48 hours later.
How to read a TEAS Science scenario stem
Read the last sentence of the stem first. The last sentence is the actual question. Read it before the scenario, not after. Then read the scenario knowing what to look for. This trick alone saves about three minutes across the section, and it cuts down on rereads.
When two answer choices look correct, choose the one with the more specific anatomical or physiological term. The TEAS rewards precise vocabulary. If one option says heart and the other says left ventricle, and the stem describes oxygenated blood pumped to the body, the answer is left ventricle.
When a question shows a results table, write a one sentence summary of what the table shows in the margin before reading the choices. This forces you to interpret the data on your own terms first, which prevents the test from steering you with a tempting wrong choice.
Common mistakes to avoid
Studying anatomy from a wall of text. Diagrams beat paragraphs every time on the TEAS. If your prep book is text heavy, supplement with a labeled diagram source.
Skipping life and physical science because anatomy is bigger. The 8 to 10 life and physical science items are the cheapest points on the section because the topics repeat each year.
Treating the TEAS like a memory contest. The TEAS rewards reasoning. Half the items can be solved by tracing a body system or interpreting a graph rather than recalling a fact.
