TExES Mathematics 7-12 (235) Practice Test & Study Guide

What is the TExES Mathematics 7-12 (235) Exam?

Do you want to teach high school math in Texas? If so, one of the landmarks on your journey to becoming the next standout educator is the TExES 7-12 (235) test! This exam tests whether you have the necessary skills and knowledge to teach high school math. Anyone wishing to teach mathematics at this level in Texas must take (and pass) this exam. It is open to those who already have a TExES teaching certificate of any kind and those who are in the process of becoming certified or wish to be certified soon.

The TExES 235 is a five-hour exam, which is broken up into two parts. The first part - lasting 15 minutes - ensures that you comply with the exam's policies and provides a tutorial on how to take the test. It is a computer-administered test (CAT), which simply means it is done entirely through a computer. After this short introduction, the test is found in the second part. This 4 hour, 45-minute section assesses your competency in six broad mathematical domains.

While taking the TExES 235, you will encounter 100 multiple-choice questions. Some of these questions might not factor into your final grade. All of that may sound daunting, but it could be of some relief to know that you will be provided with a sheet of essential formulas and definitions. You won't have to remember just everything from raw memory!

Additionally, you are allowed to bring a graphing calculator, provided that this calculator meets the exam's requirements. A full list of approved calculators is available on the TExES official website.

Practice tests give you a better idea of the topics you have mastered and those you should keep studying.

What is on the TExES Mathematics 7-12 (235) Exam?

The material on the TExES 235 test is divided into six broad domains. The exam will test your competency in all six domains. Each of them plays a vital role in math education at the middle and high school levels. We'll go through these domains in detail below so that you know exactly what to expect before you register for a test

Number Concepts

In a nutshell, you will be assessed on your knowledge of number theory and algorithms. You will need to thoroughly understand the concepts of both real and complex numbers, arithmetic and algebraic operations, and quantitative reasoning. Additionally, you will need to make sure you have a good grasp of fractions, decimals, and how to model real-world problems using numbers.

Remember those "story problems" that you used to have to solve in your high school mathematics class? This portion of the exam will test your ability to understand and solve them. Having a solid grasp of mathematical relationships will also be very helpful, as you may be required to prove certain relationships between numbers.

The concepts focused upon in this section include:

  • The real number system
  • The complex number system
  • Number theory principles and concepts

The number concepts portion of the exam accounts for approximately 14 percent of your test score. Therefore, you can expect to encounter 14 questions that test this competency.

Domain Percent of Score Approx. Number of Questions
Number Concepts 14% 14

Patterns and Algebra

As the name implies, this section is mainly geared towards testing your algebraic knowledge and your understanding of mathematical patterns. However, this domain also focuses very intensely on functions. You'll need to possess a strong comprehension of algebra, as well as an excellent understanding of trigonometric and algebraic functions. Being comfortable with both differential and integral calculus is also a must. Time to break out those differentiation rules! (Anyone remember the chain rule?)

The patterns and algebra domain of the TExES 235 concentrates on the following disciplines:

  • Using patterns to solve problems
  • Fundamental concepts behind functions and relations, as well as their graphs
  • Linear and quadratic functions
  • Radical, rational, polynomial, piecewise, and absolute value functions
  • Exponential and logarithmic functions
  • Trigonometric and circular functions
  • Differential and integral calculus

As you can see, the amount of material covered in this domain is extensive. That's a lot of studying! Because the concepts covered here are so vital to high school math education, this portion of the exam accounts for approximately 33 per cent of your overall score. It is by far the largest of the six domains included in the exam.

Domain Percent of Score Approx. Number of Questions
Number Concepts 14% 14
Patterns & Algebra 33% 33

Geometry and Measurement

This section deals with all things relating to geometry and spatial reasoning. Here, you'll be tested on your knowledge of angles, measurements, Euclidean principles, and geometric transformations. You won't need your compass and protractor, however, as the primary focus of this domain is on the theory and application of geometry.

The knowledge requirements for this leg of the exam are as follows:

  • Understanding measurement as a process
  • Understanding geometry as an axiomatic system
  • Understanding Euclidean geometry and its applications
  • Understanding coordinate geometry, including transformations and vectors

Given that geometry plays a significant role in math education - especially at the upper-middle and high school levels - this section of the test is also rather weighty. It accounts for 19 per cent of your total exam score. This makes it the second-largest portion of the test, following only behind the patterns and algebra domain.

Domain Percent of Score Approx. Number of Questions
Number Concepts 14% 14
Patterns & Algebra 33% 33
Geometry & Measurement 19% 19

Probability and Statistics

From weather forecasts to sports games, probability and statistics are important in day-to-day life. They also constitute the fourth domain on the TExES 7-12 (235) exam. This portion of the test will assess your skills with regard to graph and chart interpretation, data analysis, and theories of probability. You will want to have a good handle on formulas relating to probability, and statistical concepts such as mean, median, skewedness, and standard deviation.

The probability and statistics domain focuses on the following key concepts:

  • Numerical and graphical techniques of exploring data and patterns
  • The theory and application of probability
  • Relationships between probability theory, statistical inference, and sampling

In total, this domain of the TExES 235 accounts for approximately 14 percent of your score. That means you can expect to encounter 14 exam questions that test this competency.

Domain Percent of Score Approx. Number of Questions
Number Concepts 14% 14
Patterns & Algebra 33% 33
Geometry & Measurement 19% 19
Probability & Statistics 14% 14

Mathematical Processes and Perspectives

Unlike the previous four domains of the TExES 235, which test your "hard math" skills, the mathematical processes and perspectives domain tests your knowledge regarding the fundamentals of mathematics itself. This includes methods of proof - including indirect proof - as well as inductive reasoning and problem-solving. These concepts can be tricky, as they are rather abstract in nature.

Additionally, this domain focuses on your ability to communicate math concepts and make connections to disciplines that are not explicitly "math-related." An example of this would be connecting music and pitch with equations that describe sound waves.

Competencies tested here include:

  • Mathematical reasoning and problem solving
  • Connecting mathematics with real-world examples
  • Communicating math concepts clearly

The mathematical concepts and perspectives portion of the exam will contribute 10 percent of the total score.

Domain Percent of Score Approx. Number of Questions
Number Concepts 14% 14
Patterns & Algebra 33% 33
Geometry & Measurement 19% 19
Probability & Statistics 14% 14
Mathematical Processes & Perspectives 10% 10

Mathematics Learning, Instruction, and Assessment

This portion of the test is fundamentally education-based. It concentrates on your ability to instruct students and to teach the math curriculum. More specifically, it tests your understanding of the TEKS (Texas Essential Knowledge and Skills) standard. Additionally, you will be tested on your understanding of grading and student assessment.

This section also focuses more on the "soft skills" rather than the "hard skills" of mathematics.

The main areas of focus in this domain are:

  • Understanding how children and students learn math
  • Implementing math education in accordance with statewide standards (TEKS)
  • Understanding and implementing assessment techniques (such as testing and grading)

Following in the footsteps of domain five, this portion of the exam accounts for 10 percent of your overall score.

Domain Percent of Score Approx. Number of Questions
Number Concepts 14% 14
Patterns & Algebra 33% 33
Geometry & Measurement 19% 19
Probability & Statistics 14% 14
Mathematical Processes & Perspectives 10% 10
Mathematics Learning, Instruction, & Assessment 10% 10

How is the TExES Mathematics 7-12 Test Scored?

Like other TExES exams, this exam is graded on a scale of 100 to 300. The TExES exam passing score for Math 7-12 is 240. Each correctly-answered and graded question is worth one raw score point. As we briefly touched on earlier, the exam may contain questions that are not graded and do not count towards your final score. However, you will have no way of knowing which questions these are. The percentage of your score that each domain contributes is also approximate, so your specific version of the test may contain a slightly different mixture of questions.

The somewhat ambiguous nature of the exam's scoring system makes it impossible to tell precisely how many questions you have to answer correctly to pass. That number will vary depending upon the specific exam you take.

Given that the TExES 235 is a multiple-choice computer-administered test, the exam is scored right away. However, you will not know your score until 10 p.m. Central Time on the score report date, which varies depending upon when you take the exam. You will always receive your TExES exam results within 7 days of taking the test. Your score report will include a detailed breakdown of your performance, including:

  • Whether or not you passed
  • Your total score
  • Individual scores by domain, and - where possible - by competency

How to Prepare for the TExES Mathematics 7-12 Test

Like any exam, the main way to prepare for the TExES Math 7-12 is to study. Fortunately, there are plenty of resources for those looking to study for the exam, including TExES study guides and practice tests with TExES 235 practice questions. Utilizing these materials can help test takers become familiar with the testing format, including test format and types of questions.

In general, you will be best served by focusing most heavily on algebra, mathematical functions, trigonometry, geometry, number theory, and connecting math with other subjects. These concepts make up the "bedrock" of the TExES Math 7-12 exam. You should take as many practice tests as you can, making sure you thoroughly understand the answer to each question.
