ExploreAbout this exam
CSET: Science is one of the California Subject Examinations for Teachers, the assessment family the California Educator Credentialing Examinations site describes as covering California educator credentialing assessments. Candidates seeking a single subject teaching credential in science take it to demonstrate subject-matter competence; the chemistry option is aimed at candidates who intend to teach chemistry at the secondary level, and at candidates adding science to an existing authorization. The site lists Science, Foundational-Level General Science, and a range of other single subject areas in its test selection menu, and it notes that the Single Subject Science subtests were redeveloped, with results released in 2017. The published source does not enumerate the content domains or percentage weights for the chemistry version, so treat any domain breakdown you encounter elsewhere as unverified and confirm it against current official preparation materials. The assessment includes constructed-response questions, which the site flags as a reason score reports may be delayed. Preparation should combine a review of core chemistry coursework (stoichiometry, atomic structure and periodicity, thermodynamics, equilibrium, kinetics, organic and biochemistry) with practice writing short constructed responses that show reasoning, not just final answers. Register through the CSET program site, where fee waivers are available for eligible California residents, and check the preparation materials and policies pages before scheduling.
What you'll study
About CSET Science: Chemistry preparation
What is the format of CSET: Science (Chemistry)?
The CSET program administers computer-based tests, and the site notes online proctoring is available for some CSET tests, so you may be able to test remotely. CSET tests include constructed-response questions alongside selected-response items. The source does not state the number of questions or the time limit for the chemistry subtest, so confirm those details on the official assessment page when you register.
How hard is the chemistry subtest?
Expect it to test breadth as well as depth: general science ideas plus chemistry at a level beyond introductory coursework. The constructed-response portion is where many candidates lose points, because they state a result without showing the reasoning or the calculation. Practicing written explanations under time pressure is the highest-value preparation. The source publishes no pass rates or difficulty data.
How much does it cost, and are fee waivers available?
The site states that registration fees for the CBEST, CSET, CTEL, and RICA are waived for eligible California residents, and directs candidates to the FAQs for details about the California assessment fee waivers. The standard, non-waived CSET fee is not stated in the source, so check the current registration page for the amount that applies to you.
Can I retake the test if I do not pass?
The source does not describe a retake policy, waiting period, or attempt limit for CSET: Science. Rather than rely on secondhand accounts, check the policies and rules section of the CSET site and your score report, which typically explains your options. Plan your study so a retake is a backup rather than part of the schedule.
When will I get my scores?
The site cautions that score report dates for CSET tests with constructed-response questions may be delayed, and points candidates to test results information under the Get Results tab. Because chemistry includes constructed responses, do not assume a fast turnaround. Build slack into any credential or hiring deadline that depends on your score report.
How long are scores valid?
The site states that the period of validity of some examinations for certification is changing from five years to ten years effective 4/1/17. Whether that change applies to your specific CSET: Science result depends on when you tested, so verify your own validity window with the Commission on Teacher Credentialing rather than assuming either figure.
What order should I study in?
Start with stoichiometry, atomic structure, and periodicity, since nearly every other topic depends on them. Then move to states of matter, thermodynamics, equilibrium, and kinetics, followed by acids and bases, electrochemistry, and organic and biochemistry. Finish with timed constructed-response practice that mixes topics, because the exam does not announce which area a prompt comes from.
How do I register, and when can I test?
Register through the California Educator Credentialing Examinations site, where registration and scheduling are available for the 2026–2027 program year for CBEST, CPACE, CSET, and CTEL. Test dates, sites, and appointment availability are listed under the assessment dates and sites section. Schedule early if you need a specific date or a remote proctored appointment.
What are the most common mistakes candidates make?
Two stand out. First, answering constructed responses with a number and no reasoning, which earns little credit even when the number is right. Second, studying only advanced chemistry and neglecting the broader science context the subtest expects. Also confirm the current subtest structure before studying, because the Single Subject Science subtests were redeveloped and older prep materials may describe a retired version.
