TEAS Science Practice Test

The Test of Essential Academic Skills (TEAS) is an aptitude assessment, used as a prerequisite by many nursing programs in the United States. Developed by Assessment Technologies Institute (ATI), the TEAS evaluates students’ understanding of key concepts and analytical skills related to the nursing and health science field. Since studies show a correlation between a student’s TEAS test score and their performance in the nursing program, institutions use the TEAS as one of the determining factors for acceptance into their program.

The TEAS includes four sections: Science, Mathematics, Reading, and English & Language Usage. The science section tests students’ foundational knowledge of chemistry, human anatomy, physiology, and general biology.



Who takes the TEAS?

The Test of Essential Academic Skills (TEAS) is available for students interested in nursing programs. Many institutions in the US require the TEAS as a prerequisite for their nursing program, so students are encouraged to learn more about the institution’s eligibility requirements.

How to register for the TEAS

Students may log on to the ATI Testing website to register for the TEAS. After an application is approved, students are prompted to schedule their test date and location. Testing locations include PSI testing centers and schools that offer the test on-site.

How much does it cost to take the TEAS?

The TEAS exam fee is typically between $60 and $140, depending on the testing location. Students can take the exam at a PSI testing center or a registered school.

How many questions are on the TEAS Science exam?

The TEAS Science exam has 50 questions. This section contains six “pretest” questions that are not calculated with your final score.

How long is the TEAS Science exam?

Test-takers have 60 minutes to complete all 50 questions on the Science section of the TEAS.

Can you use a calculator for the TEAS?

Yes. At the beginning of the exam, a proctor will provide test-takers with a four-function calculator. Students are not allowed to use calculators with special functions.

What is a passing TEAS Science score?

Finding out the nursing program’s score requirements is important. With the TEAS, there is no pass-fail score. You will receive a total or “main” score which includes the individual scores from all four sections (Science, Reading, Mathematics, and English & Language Arts). You will also receive the separate scores for each section. Typically, a program requires you to earn a score of at least 60% to 70%. But, it is highly competitive to gain admission into a nursing program, so students are encouraged to aim for higher than the program’s requirements.

What topics are on the TEAS Science exam?

The TEAS Science section tests students’ ability to:

  • Demonstrate knowledge of the general orientation of human anatomy
  • Describe the anatomy and physiology of the following systems:
    • Respiratory system
    • Cardiovascular system
    • Digestive system
    • Nervous system
    • Muscular system
    • Male and female reproductive systems
    • Integumentary system
    • Endocrine system
    • Urinary system
    • Immune system
    • Skeletal system
  • Describe cell structure, function, and organization
  • Describe the relationship between genetic material and the structure of proteins
  • Apply concepts underlying Mendel’s laws of inheritance
  • Describe the structure and function of the basic macromolecules in a biological system
  • Describe the role of microorganisms in disease
  • Recognize basic atomic structure
  • Know the physical properties and changes of matter
  • Describe chemical reactions
  • Demonstrate how conditions affect chemical reactions
  • Understand properties of solutions
  • Describe concepts of acids and bases
  • Use basic scientific measurements and tools
  • Apply logic and evidence to a scientific explanation
  • Predict relationships among events, objects, and processes
  • Apply the scientific method to interpret a scientific investigation

What to expect on test day

Students can take their TEAS exam at a PSI testing center or a registered school location. Below you find some common tips and rules for test day:

  • Plan to arrive at your testing location at least 15 minutes early. If you are more than 15 minutes late, you risk forfeiting your test and exam fee.
  • Bring a government-issued ID that includes your photo, your signature, and your permanent address. Credit card photos, student IDs, and expired IDs are not accepted.
  • Bring two sharpened No. 2 pencils with attached erasers.
  • You may not bring personal bags, coats, sunglasses, and electronics in the testing area.
  • There is no food or drink allowed in the testing area unless it is for medical reasons.
  • A proctor will provide you with scratch paper and a four-function calculator.
  • You will have a 10-minute break after the mathematics section of the exam. Any other breaks will deduct from your test time.
