The TEAS Science section is a subset of the overarching ATI TEAS exam, currently in its Version 7 format.

It is designed by Assessment Technologies Institute (ATI) to assess the essential academic skills needed for success in nursing and allied health programs.

The Science section specifically evaluates your foundational knowledge of key scientific concepts that will be crucial during your medical education and future career.

This subtest is for students applying to Registered Nursing (RN), Licensed Practical Nurse (LPN/LVN), and various allied health programs (like dental hygiene or radiologic technology) in the United States.

It is not a "pass/fail" test in the traditional sense, but rather a tool schools use to gauge your academic readiness and competitiveness compared to other applicants.

What the Course Entails and Exam Details

The ATI TEAS Science 2026 exam encompasses four primary content domains:

I. Human Anatomy & Physiology (A&P)

This is the largest and most critical section.

You will face questions about all major human body systems, including their structure, function, and interactions.

Topics include: cardiovascular, respiratory, digestive, nervous, endocrine, reproductive, integumentary (skin), muscular, skeletal, urinary, and immune systems.

II. Biology

This section covers fundamental biological principles.

You should prepare to answer questions on cell biology (cell structures, functions, and processes like mitosis and meiosis), genetics (inheritance patterns, DNA structure), microbiology, and basic biological concepts.

III. Chemistry

The chemistry subtest assesses your knowledge of basic chemical principles.

Focus areas include: atomic structure, states of matter, chemical bonds (ionic and covalent), chemical reactions and equations, properties of water, solutions, and pH.

IV. Scientific Reasoning

This domain tests your ability to think critically and apply the scientific method.

You will need to understand scientific research methods, design experiments, interpret data, analyze graphs and tables, and draw valid scientific conclusions from provided information.

Exam Details (Based on ATI TEAS 7 format):

• Total Questions: The entire TEAS exam has 170 questions. The Science section specifically contains 50 questions. (While this article's focus is on a 44-question practice test, the official final exam contains 50 questions).
• Unscored Questions: Of the 50 Science questions, 6 are unscored "pretest" items used by ATI for future testing development. You will not know which questions are unscored.
• Total Time for Science Section: You will have 60 minutes to complete the Science subtest. This means you must manage your time effectively, aiming to spend just over one minute per question.

 What to Expect in the Final Exam

On test day, you can expect the following structure for the TEAS Science portion:

• Question Format: The primary format is multiple choice with four options (A, B, C, D). There may also be alternate-format questions, such as select-all-that-apply, fill-in-the-blank, ordered response, or hot-spot questions, though multiple choice remains dominant.
• Scoring: You are not penalized for incorrect answers. Your score is based solely on the number of questions you answer correctly.
• Scores and Passing Requirements: There is no uniform "passing score" for the TEAS Science section. Instead, each individual nursing or allied health program sets its own minimum required score for admission. For competitive programs, aim for a score in the "Advanced" (78%-90%) or "Exemplary" (90.7%-100%) range. A "Proficient" score (58.7%-77.3%) is often the minimum accepted, but a higher score makes your application much stronger.
• Calculator: For the entire TEAS exam, you will be provided with a fundamental, four-function calculator, typically integrated into the testing interface. You may not bring your own.
• Rules: Standard standardized testing rules apply. No phones, notes, or outside materials are allowed in the testing area.

 How to Study and Exam Centers

Effective preparation is key to conquering the TEAS Science section. Here are actionable study strategies and information on where to take the test:

Actionable Study Strategies:

Use High-Quality Practice Tests: A dedicated tool like the "TEAS Science Practice Test 2026 (44 Questions Answers)" is invaluable. Take it multiple times to familiarize yourself with the question style, difficulty, and to build your testing stamina. Carefully review both correct and incorrect answers.

Focus on Weakness Areas: Use practice test results to identify which Science domains (A&P, Biology, Chemistry, or Reasoning) need the most attention. Don't waste time reviewing what you already know perfectly.

Master Human A&P: Since Anatomy & Physiology is the largest section, prioritize this content. Utilize flashcards for complex systems, terminology, and hormone interactions.

Practice Time Management: During your study sessions, time yourself to mimic the 60-minute limit of the real exam. Learn to make educated guesses and move on when necessary, ensuring you answer every question.

Simulate Real Conditions: Take at least one full-length TEAS practice exam (Reading, Math, Science, English) in a quiet environment, replicating true testing conditions.

Review Core Content: Do not rely solely on practice tests. Review the foundational scientific concepts using reliable textbooks, online courses, or ATI's official study materials.

Exam Centers and Where to Take the Exam:

• Online Proctored (At Home): ATI offers the option to take the TEAS online from your own home, using a remote proctoring service.
• At Your Institution: Many nursing and allied health schools proctor the TEAS on their own campuses. Contact your intended school's admissions office directly to find out if this option is available.
• Authorized Testing Centers: You can also take the TEAS in person at an authorized testing vendor's physical location, such as PSI testing centers, which have locations throughout the United States.

To register, you must create an account on the ATI testing website (atitesting.com), select your preferred testing location (online, institution, or PSI), and pay the registration fee. Always confirm deadline dates with the programs you are applying to.

Job Opportunities from the Course

Passing the TEAS and achieving program admission is the crucial first step on your path to a rewarding and stable career in healthcare.

While the TEAS itself is not a license, a strong score is required for entry into programs that unlock these professional roles:

• Registered Nurse (RN)
• Licensed Practical Nurse / Licensed Vocational Nurse (LPN/LVN)
• Dental Hygienist
• Radiologic Technologist
• Respiratory Therapist
• Surgical Technologist
• Physical Therapist Assistant (PTA)
• Veterinary Technician
• Occupational Therapy Assistant (OTA)
• Clinical Laboratory Technician

The healthcare sector is experiencing significant growth, and the demand for qualified professionals is projected to continue for the foreseeable future. A successful career begins with a stellar performance on the TEAS Science section.

Best of luck with your studies! By utilizing a strategic preparation plan and high-quality practice resources, you can approach the TEAS Science 2026 Practice Exam with confidence.
