TExES Chemistry 7-12 Practice Test & Study Guide

What is the TExES Chemistry 7-12 Exam?

The TExES Chemistry 7-12 exam is one of several content-specific exams used by the state of Texas to test the skills of future educators in a given subject area. In this case, The TExES Chemistry 7-12 test is designed to test the skills and knowledge of aspiring chemistry teachers for middle and high school students (grades 7 through 12). The exam is part of the Texas Educator Certification Examination Program, which means that those who pass the exam will earn TExES teacher certification to teach the subject in public schools in the state.

This computer-based exam includes both scored and unscored questions. Scored questions test candidates' abilities in various areas of the field, and are divided into four different domains:

  1. Scientific Inquiry and Processes
  2. Matter and Energy
  3. Chemical Reactions
  4. Science Learning, Instruction, and Assessment

Here, we will discuss various aspects of the TExES Chemistry 7-12 exam to help test takers prepare for test day.

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

What Material is Covered on the TExES Chemistry 7-12 Exam?

The TExES Chemistry 7-12 exam covers a range of topics and skills, or competencies, that future chemistry teachers should be able to meet. In total, the TExES Chemistry exam tests 17 competencies, with 4 competencies in Scientific Inquiry and Processes, 7 in Matter and Energy, 4 in Chemical Reactions, and 2 in Science Learning, Instruction, and Assessment. Let's examine each domain and the different competencies in greater detail.

Scientific Inquiry and Processes

The first domain, Scientific Inquiry and Processes, covers 6 different physical science standards across 4 competencies. This domain is more general in nature and covers concepts appropriate for grades 7 through 12 that are common to multiple areas of science, not just chemistry. For example, this section tests candidates' general skills and knowledge of the scientific process, including scientific inquiry, the use of appropriate tools and methods, and the history of science. This section also explores a candidates' ability to teach science, manage a classroom, and unify concepts across multiple science-related disciplines. Test takers in this domain will demonstrate their understanding of the following competencies:

  • How to choose and oversee safe scientific learning activities using various technologies and materials
  • Science and the scientific inquiry process
  • How math and other unifying concepts are used in various disciplines of science
  • The history of science and how science impacts society and daily life

Matter and Energy

The second domain, Matter and Energy, is the largest domain and makes up a little less than half of the exam (candidates may want to schedule their studying time to match this ratio). It focuses on state standards in the field, and tests candidates in 7 different competencies. In general, it includes questions about the various kinds and properties of matter and energy, including at the smallest scale and chemical processes that can change them. Specific laws and concepts are tested such as gas laws, atomic orbitals, chemical bonds, solutions, and more. Candidates may have to make various kinds of calculations, such as finding the molarity of a solution, solving stoichiometric problems, or solving problems in calorimetry. Testers should be prepared to answer questions related to the following competencies:

  • Matter characteristics
  • Atom structure and characteristics
  • Gas properties
  • Ionic vs. covalent bonds
  • Chemical notation and chemical equations
  • Solution types and properties
  • Energy transformations for physical or chemical processes

Chemical Reactions

The Chemical Reactions domain also tests specific state standards for chemistry. Test takers will be asked about a range of chemical reactions across 4 different competencies. Questions may require testers to solve problems, identify properties, explain concepts, or analyze reactions. For instance, candidates may be asked to analyze the reaction of a specific acid-base titration or need to identify the chemical properties of a household chemical.

Essentially, this domain includes various concepts that do not fall under the larger umbrella of Matter and Energy, but are still important to the field of chemistry, such as nuclear reactions and concepts of equilibrium. Test takers may need to know some of the applications of these different reactions such as the role of oxidation and reduction in batteries. Specifically, candidates will be asked about their understanding of the following competencies:

  • Equilibrium and chemical kinetics
  • Acids, bases, and acid/base reactions
  • Oxidation and reduction
  • Nuclear reactions (fission, fusion)

Science Learning, Instruction, and Assessment

The final domain, Science Learning, Instruction, and Assessment, is more like the first domain in that it is more general in nature. However, it focuses on evaluating candidates' skills for teaching science to students in grades 7 through 12. Test takers will need to understand how students learn science and how to choose the appropriate assessments to track scientific learning over time.

Candidates are only tested on 2 competencies in this section, but each one incorporates a range of specific skills for learning and teaching strategies. Specific topics in this domain may include inquiry strategies, active learning methods, characteristics of assessments, and teacher expectations. Test takers will be evaluated on the following competencies:

  • Their understanding of how to teach science, how students learn science, and how to include scientific inquiry in their instruction
  • Their skills in monitoring and assessing science learning in various settings, such as a classroom vs. laboratory

Testing Logistics


The TExES Chemistry 7-12 exam is scored on a scale of 100 to 300. A TExES exam passing score is set at 240. There are four different scores that are reported on the candidate's score report: total test performance, performance by each domain area, performance by competency, and holistic score. The total test performance score will notify candidates whether they passed the exam or not. The holistic score is for constructed-response questions, which are not included on the TExES Chemistry 7-12 exam. Test takers will earn one raw point for each correct answer, which are then added up for the total raw score.

Those who take the TExES Chemistry 7-12 exam can expect to receive their scores within about 7 days. Testers who choose to receive their scores via email are notified at 10 pm Central on their TExES score report dates. Those who do not pass the exam on their first try are allowed up to five total attempts, after which testers who have yet to pass must complete a test-limit waiver and have it approved.


TExES Chemistry 7-12 exam dates are available throughout the entire year. Test takers can use the Pearson website to explore available dates, but usually it's available every day of the year.
