TExES Life Science 7–12 (238)

The TExES Life Science 7–12 (238) is a Texas teacher certification content exam for candidates preparing to teach life science in grades 7–12. It assesses whether candidates have the subject-matter knowledge expected of a secondary life science teacher; it is not a college admissions test. Whether you need to take it, and when you may register, depends on your certification route and educator preparation program. Check with your program and the Texas Education Agency for current eligibility and registration requirements.

The exam covers broad life science knowledge and scientific practices, including inquiry, measurement, experimental design, laboratory safety, and the use of scientific equipment. Other areas include chemistry, water, biomolecules, cell structure and function, and membrane transport, alongside topics such as genetics, evolution, organisms, and ecology. Review the current TExES test framework for the official domains and their scope. Effective preparation means connecting core concepts to evidence, interpreting investigations, and practicing careful reasoning—not just memorizing vocabulary.
