TExES Mathematics 4–8 (115) Exam Format and Structure

The TExES Mathematics 4–8 (115) exam is designed to measure how well you understand math concepts and how prepared you are to teach them to students in grades 4 to 8. The test is computer-based and includes multiple-choice questions.

You will have 5 hours to complete the exam. It has about 100 selected-response (multiple-choice) questions.

The questions cover six main areas:

  •    Number concepts: Understanding whole numbers, fractions, decimals, place value, number operations, and how to explain them to students.
  •    Patterns and algebra: Recognizing patterns, solving equations and inequalities, and teaching algebraic thinking.
  •    Geometry and measurement: Working with shapes, spatial reasoning, formulas, and units of measurement.
  •    Probability and statistics: Understanding data, graphs, averages, chance, and how to help students interpret information.
  •    Mathematical processes and perspectives: Using logical thinking, solving word problems, and teaching students how to approach math step by step.
  •    Mathematics learning, instruction, and assessment: Knowing how to plan lessons, use teaching tools, check student understanding, and support diverse learners.


This exam evaluates your math knowledge and your teaching skills. It’s important to study both the content and the best ways to teach it to middle school students.

Preparing for the TExES Mathematics 4–8 (115): Study and Test-Taking Strategies

Getting ready for the TExES Mathematics 4–8 exam takes time and planning. In this section, we’ll help you with practical ways to study, manage your time, and stay calm on test day. The goal is to help you feel confident and well-prepared.

How to Start Your Study Process

Before you begin, take a moment to understand how you learn best. Some people learn well by watching videos, while others prefer reading, writing notes, or using hands-on materials. 

Knowing your learning style will help you choose the best study tools.

Next, set a timeline that fits your schedule. Most people do well with 4 to 8 weeks of study time. Set weekly goals to stay on track and keep your study sessions focused.

Create a Study Plan That Works

A good study plan helps you stay organized and avoid last-minute cramming. It also helps you balance studying with your other responsibilities.

Start by looking at your daily routine and finding time blocks where you can study. Treat your study time like an appointment. Leave some space in your schedule for unexpected things, like feeling tired or being busy at work.

Set a clear goal each week. Use different study tools to keep things interesting. If a topic is harder than expected, adjust your plan and give yourself more time to learn it.

Practice and Review Regularly

Taking practice tests is one of the most effective ways to prepare for the exam. Start with a short practice test to find out which topics you need to work on. After that, spend more time reviewing the topics where you scored the lowest.

After each practice session, take time to review the questions you got wrong. Try to understand why the correct answer is right and why your answer was not. This will help you learn faster and avoid the same mistakes.

It also helps to keep a notebook or chart to track your scores. This lets you see how much progress you are making over time.

Join a Study Group

Studying with others can make learning easier and more enjoyable. A study group gives you the chance to ask questions, share ideas, and stay motivated.

You can find or join study groups on:

  •    Facebook groups or Reddit forums for TExES test takers
  •    Local colleges or educator prep programs
  •    Online apps like Discord or Meetup
  •    Teacher support groups in your area

Enroll in a Professional Prep Course

If you want more guidance, a prep course might be a good choice. These courses give you a step-by-step plan, practice tests, and help from experienced teachers.

The Learning Liaisons offers a full prep course for the TExES Mathematics 4–8 (115) exam. When you enroll, you get instant access to:

  •    Get 7 to 8 hours of sleep in the days before your test so you feel alert and focused.
  •    Eat a healthy meal before the exam to fuel your brain and avoid distractions during the test.
  •    Avoid too much caffeine or sugar, and skip anything that might affect your focus or energy.
  •    Practice deep breathing or light stretching before the test to stay calm and relaxed.
  •    Read every question carefully, paying attention to tricky wording.
  •    Don’t waste too much time on hard questions. Mark them, move on, and come back later.
  •    Use your scratch paper to do calculations or organize your thinking during the test.
  •    Manage your time wisely. Keep an eye on the clock and use all the time you're given.
  •    Stay positive and focus on your own progress.
