The California Subject Examinations for Teachers (CSET) are a set of exams designed to assess subject matter knowledge for those planning to teach in California's public schools. The specific CSET exam you must take depends on the subject and grade-level you plan to teach. For example, if you plan to teach elementary school or special education, you typically must pass the CSET Multiple Subjects exam, while if you plan to teach a specific subject at the secondary school level, you must pass a CSET Single Subject exam such as Mathematics, Science, Social Science or English. You also usually need to take the CSET Writing Skills exam if you have not already passed the Writing section of the California Basic Educational Skills Test (CBEST).
