ATI TEAS Science 2026-2027 : 1000 MCQ with Answers

ATI TEAS Science is one of the four sections of the Test of Essential Academic Skills, an admission exam used by many nursing and allied health programs. It assesses foundational knowledge of human anatomy and physiology, biology, chemistry, and scientific reasoning.

The Science section generally contains 50 questions and has a 60-minute time limit under the current TEAS format. Some questions may be unscored pretest items, so candidates should confirm the latest structure with ATI or their testing institution.

The section focuses mainly on human anatomy and physiology, biology, chemistry, and scientific reasoning. Important areas include body systems, cells, genetics, hormones, immunity, nutrition, basic chemistry, and interpreting scientific information.

Many candidates find anatomy and physiology challenging because it covers several body systems and requires understanding how they work together. The difficulty varies by background, so reviewing structures, functions, and common medical terminology can make this area more manageable.

There is no single national passing score for the Science section. Each nursing or healthcare program sets its own admission requirements, and some consider the total TEAS score as well as individual section scores. Check the requirements of every program to which you plan to apply.

Begin by reviewing the official test objectives and identifying weak areas with a diagnostic quiz. Study one system or concept at a time, use diagrams and active recall, and complete timed practice questions while reviewing why each answer is correct or incorrect.

Yes. Biology concepts can include cells, genetics, cellular processes, and body-system relationships, while chemistry may include matter, chemical reactions, solutions, and basic biological chemistry. The level is generally introductory rather than equivalent to an advanced college science course.

ATI TEAS Science is a computer-based standardized test, not a hands-on laboratory practical. Questions may still assess scientific reasoning, experiments, data interpretation, and the application of basic biology, chemistry, and anatomy concepts.

ATI TEAS testing dates are not set as one universal annual schedule. You may take the exam through an approved testing center, a school, or an available remote-testing option, depending on the provider. Contact your target program or ATI for registration windows, identification rules, fees, and available dates.

Eligibility depends on the nursing or allied health program, because schools may set their own prerequisite, application, and retest rules. Some programs require specific science courses or allow testing only during an application period, so review the admissions instructions before booking your exam.
