About this exam
The Praxis Chemistry (5245) is a subject assessment for people preparing to teach chemistry, often as part of a state teacher-certification process. It measures chemistry knowledge relevant to teaching rather than serving as a general college-admissions test. Who must take it and how a score is used depend on the state, certification route, and employer, so candidates should check their state education agency’s current requirements before registering.
The exam covers core chemistry knowledge and the ability to interpret scientific information. Review scientific inquiry and experimental design; measurement, significant figures, and data analysis; atomic structure, isotopes, and electron configurations; and periodic trends and element properties. Preparation also means connecting concepts, interpreting data, and applying chemistry to unfamiliar questions—not just memorizing definitions. Check the current ETS Praxis Chemistry Study Companion for the test structure, content specifications, and sample questions, since official details and state requirements can change.
How to prepare for the Praxis Chemistry (5245)
- Use the current ETS Study Companion to map the exam’s content areas, then make a review plan that gives extra time to weaker topics.
- Practice explaining experimental design, significant figures, and data analysis, and review atomic structure, electron configurations, and periodic trends with worked examples.
- Take timed sets of selected-response questions, then review why each answer is right or wrong; confirm test-day and certification requirements with ETS and your state agency.
