Updated November 20, 2023
The ATI TEAS science test is an entrance exam required by some nursing programs.
It is one of four sections and consists of 50 questions with a 60-minute time limit.
The other sections are reading, math and English.
All four subjects combined consist of 170 questions. The assessment areas include human anatomy and physiology, biology, chemistry and scientific reasoning.
What Is the ATI TEAS Science Test?
The ATI Test of Essential Academic Skills (TEAS) science test is one of four sections required for entry to some nursing programs across the US.
The other sections include Reading, Math and English.
In the TEAS science exam there are 50 multiple-choice questions and a time limit of 60 minutes.
The test is designed to identify those applicants that possess the knowledge and skills essential for passing the nursing program.
Assessment areas include:
- Human Anatomy and Physiology – 18 questions that measure your understanding of the human body and the systems that maintain it such as digestive, nervous, respiratory, muscular, skeletal, immune and urinary systems.
- Biology – Nine questions assessing your understanding of cell structure, organization and function, Mendel’s Law of Inheritance, macromolecules, microorganisms and relationships between structured proteins and genetic material.
- Chemistry – Eight questions testing your knowledge of chemical reactions, atomic structures, acids and bases and matter.
- Scientific Reasoning – Nine questions measuring your ability to apply logic and evidence to scientific explanation, use of scientific tools and measurement, predict outcomes and apply scientific methods to solve investigations.
As there is a lot of specialist information that you need to know, taking the time to study and complete TEAS science practice questions is essential if you want to pass.

When Is the ATI TEAS Science Test Taken?
As the TEAS science test is an entry exam, it needs to be taken before the application deadline.
Each school has its own application process, deadline, policy regarding retaking tests, and test fees.
You should confirm all of these before registering for your TEAS and factor in any possible resits (if permitted).
You will take the science test at the same time as the other three subjects.
You can register for your test on the ATI website.

How to Prepare for the ATI TEAS Science Test
TEAS science questions cover a lot of different topics so proper preparation is essential.
Past applications have recommended at least eight weeks of study and preparation if you hope to pass the first time.
The best ways to prepare are:
Step 1. Invest in a TEAS Science Study Guide
You will need a study guide to ensure you don’t miss any areas. There are a lot of topics in the science section and you don’t want to lose marks because you forgot to study an area.
Step 2. Research the Test
Step 3. Complete an ATI TEAS Science Practice Test
There are lots of free and paid practice tests online for you to work through. It is the best way to prepare as it helps familiarize you with the test and question format.
Step 4. Practice Time Limits
When completing TEAS 7 science practice tests start by working through at your own pace. As you become more confident with the questions and topics, start adding time limits until you can answer 50 questions in 60 minutes.
Step 5. Take Care of Yourself
When preparing for entry tests, we tend to sacrifice our health and wellbeing. While that might give us a couple of extra hours a day to study, in the long term it does affect your concentration levels and ability to retain information. Ensure you get enough sleep, eat healthy and drink plenty of water.
Step 6. Create a Study Schedule
As well as having TEAS science test practice, you will also need to prepare for the math, reading and English tests. Create a schedule so you know what to study and when ensuring no topics get left out.
What Is the Passing Score For TEAS Science?
Each school decides its own passing score. As the science test covers areas specific to the nursing profession achieving a high score in this section is essential.
Generally speaking, you should aim for around 70% but higher is always better. Especially if you have applied for a prestigious program.
Your final scorecard will have three scores and an ATI Academic Preparedness Level.
The scores are:
- Total Score – For all four sections combined
- Content Area Scores – For each test section
- Sub-Content Area Scores – Breakdown of each sub-category
The Total Score and Content Area Scores are calculated using the percentage of correct answers and adjusted depending on the questions you answered.
Not all questions carry the same weight and the computer will randomly assign them.
You won’t know if you have answered any of those questions and there is no information sharing how those questions are scored.
Equally, some of the questions are unscored and used for research purposes. Again, you will not know which ones.
There is also no negative scoring. If you do struggle with a question, take an educated guess rather than leave it blank.
The Sub-Content Area Scores are calculated the same way but no adjustments are made for the different questions.
Your scores are then combined to produce an ATI Academic Preparedness Level.
- Developmental: 0 to 40%
- Basic: 40 to 58%
- Proficient: 58 to 79%
- Advanced: 80 to 91%
- Exemplary: 91 to 100%
To ensure you score in the top percentiles give yourself enough time to prepare and complete as many paid or free TEAS practice science tests as you can.
