Encompassing all parts of the scientific world, the TEAS test science portion has numerous topics covered on the test. From anatomy and physiology to life sciences and even your scientific reasoning. You will need a working knowledge of all the subjects of science to do well in it.

Since it is a nursing exam, the emphasis on anatomy and physiology is stronger than the knowledge of other topics you will need on the exam. However, being a nursing student means that you may need to spend more time brushing up on those other topics that you don’t talk much about.

In the following sections of this article, we will talk about how many questions you can expect to see on the TEAS test science portion and what topics will be covered in the TEAS science questions.

In the totality of the Assessment Technologies Institute (ATI) Test of Essential Academic Skills (TEAS), there are 170 questions that you should answer in 209 minutes.

The TEAS science section has the most questions and time to complete. You must answer 50 multiple-choice questions in 60 minutes, which allows you one minute and twelve seconds for each answer on the TEAS science portion.

There will likely be some TEAS science questions that you can answer very quickly with knowledge you have on hand, so you will have some extra time to think on some of the questions that may require more thinking than others.

The best way you can practice for the timed aspect of the TEAS science test is to take a free TEAS science practice test and time yourself. This will teach you what types of questions you can whiz by and which ones you need some more time so you can manage it for the test.

There are 6 unscored questions on the TEAS science test. However, you don’t know which 6 are unscored, so you should answer every question to the best of your ability.

Also, there are no deductions for answering a question incorrectly, so you should try to answer all the questions you can if you are running low on time.

Subject + Sub-Topics # of Questions
TEAS Science 50 Total Questions
Anatomy and Physiology 18 Questions
Biology 9 Questions
Chemistry 8 Questions
Scientific Reasoning 9 Questions
Unscored Questions 6 Questions

The TEAS science test is divided into three categories of science: human anatomy and physiology, life and physical sciences, and scientific reasoning. Those three categories cover anatomy and physiology, biology and genetics (life science), and chemistry (physical science).

Within those subjects, there are even more fine points covered in the TEAS science exam. Here are some finer points that you should familiarize yourself with if you haven’t taken a science class in a while:

  • Demonstrate a working knowledge of the orientation of human anatomy
  • Explain the anatomy and physiology of the following body 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 in the body
  • Explain the relationship between genetic material and the structure of a protein
  • Apply the concepts outlined in Mendel’s law of inheritance
  • Describe the structure and function of macromolecules in a biological system
  • Explain how microorganisms function in diseases
  • Recognize and label basic atomic structure
  • Know and identify the physical properties and changes of matter
  • Be able to explain chemical reactions
  • Demonstrate how outside conditions affect chemical reactions
  • Understand periodic properties of solutions
  • Differentiate between and describe concepts of acids and bases
  • Use scientific measurements and tools
  • Apply logic and evidence to scientific explanations
  • Predict how events, objects, and processes relate to one another
  • Know how to use the scientific method to interpret scientific investigations

As you can see, there are a lot of various topics of study covered on the TEAS science test. If you aren’t sure about some of the topics or if you don’t think you could do what is required, it may be a good idea to find a way to brush up on those topics.

If you aren’t sure where to begin, the next section of this article will tell you the best ways to prepare for the TEAS science exam.

The first thing you need to know is that there isn’t a pass-fail scale that the TEAS test runs on. Most of the time, there is a predetermined score that you need to reach if you want to get into a specific nursing program. The normal range is at least 60-70%.

If you get the very low end of that spectrum, you only need to answer 30 questions correctly to pass the test in the standards of most nursing schools.

But, with so many areas of science covered on the test, how can you be sure you are properly prepared to answer 30 of them? We have developed a comprehensive guide to preparing for the TEAS science test.

Prep Course

There are also prep courses that you can take if you aren’t sure where to begin studying. They will provide you with the most recent information needed to study for the TEAS science exam, so you can be certain you are studying the right topics. Our recommended provider, BoostPrep, offers a great TEAS prep course.
