About TEAS 7 Science Section

The TEAS 7 Science Section assesses your knowledge of scientific principles relevant to nursing. It covers four main areas: Anatomy & Physiology (understanding the body’s systems and functions), Biology (basic cellular processes and genetics), Chemistry (the periodic table and basic reactions), and Scientific Reasoning (analyzing data and drawing conclusions).

There are 50 questions in total, but 6 are unscored pretest questions. You’ll have 60 minutes to answer the remaining 44 scored questions. The format includes multiple choice, fill-in-the-blank, image-based questions, and matching.

Frequently Asked Questions About the TEAS 7 Science Section

TEAS Science section has 50 questions done in a 60-minute timeframe, which means 72 seconds per question. Covers the key topics: Biology(9 questions), Human Anatomy and Physiology (18 questions), Chemistry( 8 questions), Science reasoning( 9 questions), and 6 unscored questions. Here’s a breakdown of the science section:

  • Human Anatomy and Physiology (40% of questions): These questions will focus on the structure and function of the human body systems.
  • Biology (20% of questions): These questions will cover general biological concepts like cellular processes, genetics, and ecology.
  • Chemistry (20% of questions): These questions assess your understanding of basic chemical principles, compounds, and reactions.
  • Scientific Reasoning (20% of questions): These questions evaluate your ability to analyze scientific data, draw conclusions, and apply the scientific method.

The TEAS science is categorized into three sections Scientific Reasoning, Human Anatomy and Physiology, and Life and Physical Sciences.

Scientific Reasoning:  This section assesses your ability to analyze research methods, interpret scientific data, and conclude the evidence you find. You will be asked to evaluate experimental designs, identify weaknesses and strengths of research studies, and apply scientific principles to solve problems. 

 Human Anatomy and Physiology: In this section, you will be tested on the structure and functions of the human body. You need to familiarize yourself with the major organ systems, their components, and how they work together to maintain homeostasis.

Life and Physical SciencesThis section covers a variety of topics from biology to chemistry, and physics. In biology, you may be asked about cells, tissues, organs, and organ systems, as well as the basic concepts of genetics, microbiology, and ecology. In chemistry, you may be asked about atomic structure, chemical reactions, and basic laboratory techniques. In physics, you may be asked about motion, forces, energy, and matter.

To properly prepare for the TEAS exam, follow the following guide or use our free TEAS test study guide:

Familiarize yourself with the main areas covered in the Science section: Human Anatomy & Physiology (40% questions), Biology (20% questions), Chemistry (20% questions), and Scientific Reasoning (20% questions).

Understand the question format: Understand  TEAS science questions will be multiple-choice, so you are required to select the most accurate answer.

Time allocation:  Dedicate sufficient time for studying each scientific discipline based on the weightage (e.g., dedicate more time to Human Anatomy & Physiology).

Identify your strengths and weaknesses: Take our updated ATI TEAS 7 practice test and gauge your current knowledge through self-assessment to understand areas requiring more focus.

The TEAS 7 Science Section has a set time limit designed to assess your knowledge efficiently. Here’s a breakdown of the duration:

  • Total Time Allotment: You’ll be given 60 minutes to complete the entire TEAS 7 Science Section.

  • Important Note: There are six unscored pretest questions included in the section. These questions are used by the test developer to evaluate potential future TEAS questions and don’t count towards your final score.

  • Effectively Utilizable Time: Since the six pretest questions aren’t scored, you’ll have 60 minutes to answer the remaining 44 scored questions. This translates to roughly 1.36 minutes per scored question.

Tips for Effective Time Management:

  • Don’t Get Stuck: If you’re struggling with a particular question, don’t waste too much time on it. Move on and come back to it later if you have time remaining.
  • Prioritize Understanding: While the time limit exists, prioritize understanding the question and answer choices fully before selecting your response. Rushing through questions can lead to careless mistakes.
  • Practice with Timed Tests: Utilize TEAS prep resources that offer timed practice tests specifically designed for the TEAS 7 Science Section. This will help you get accustomed to working under pressure and develop strategies for managing your time effectively during the actual exam.

By understanding the time constraints and practicing with timed tests, you can approach the TEAS 7 Science Section with a plan for efficient time management. Remember, prioritize understanding and accuracy over speed, but also be mindful of the time limit to ensure you have a chance to answer all the scored questions.

There’s no single “passing score” for the TEAS 7 Science Section. Here’s why:

  • Program-Specific Requirements: Each nursing or allied health program determines its own minimum score requirements for each TEAS section, including Science. It’s crucial to check with your desired program to find out the specific score you need in Science for admission.

  • Varied Ranges: Generally, program requirements for the TEAS 7 Science Section can range anywhere from 55% to 75%. More competitive programs might have higher score requirements in Science.

Here’s what you can do to find out the passing score for your program:

  • Program Website: Many nursing programs clearly outline their admissions requirements, including the TEAS minimum scores for each section, on their official website.
  • Admissions Office: Contact the admissions office of your desired program and inquire about their specific TEAS Science score requirements. This is the most reliable way to get the most up-to-date information.

The TEAS 7 Science Section assesses your foundational knowledge in scientific areas relevant to healthcare professions. Here’s a breakdown of the question types you can expect to encounter:

Content Areas:

  • Anatomy and Physiology (A&P): This is a major focus, testing your understanding of the human body’s structure and function. Expect questions on:

    • Major organ systems (respiratory, cardiovascular, digestive, nervous, etc.)
    • Cells, tissues, and organs and their interactions
    • Body processes and how different systems work together
  • Biology: Brush up on the building blocks of life! Be prepared for questions on:

    • Cellular processes (mitosis, meiosis, cell respiration)
    • Genetics and heredity
    • The scientific method and research design
  • Chemistry: Don’t worry, it’s not a full-blown chemistry exam! However, understanding the following will be helpful:

    • The periodic table of elements and their properties
    • Basic chemical reactions and formulas
    • States of matter (solid, liquid, gas)
  • Scientific Reasoning: This is like the dessert – applying your knowledge! Here, you’ll be challenged to:

    • Analyze scientific data (graphs, charts, tables)
    • Interpret results of experiments or studies
    • Draw sound conclusions based on scientific evidence

Question Formats:

While the specific questions will vary, the TEAS 7 Science Section uses a variety of formats to test your understanding:

  • Multiple Choice: The classic format – choose the best answer from a list of options.
  • Fill-in-the-Blank: Test your knowledge by providing the missing word or phrase in a scientific statement.
  • Image-Based Questions: Put your visual thinking skills to the test by analyzing diagrams or figures related to scientific concepts and answering questions based on them.
  • Matching: Demonstrate your understanding by matching terms or descriptions to their corresponding definitions.

Additional Notes:

  • Remember, there are six unscored pretest questions. These questions are used by the test developer and don’t count towards your final score.
  • You’ll have 60 minutes to answer the remaining 44 scored questions. This translates to roughly 1.36 minutes per question, but prioritize understanding over rushing.

By familiarizing yourself with the content areas, question formats, and time constraints, you can approach the TEAS 7 Science Section with confidence. Utilize TEAS prep resources like practice tests, study guides, and online tutorials to solidify your foundational knowledge and practice applying your scientific understanding to various scenarios.
