The California Basic Educational Skills Test, also known as the CBEST, tests your competency with reading, writing and math. To pass the CBEST, you need a combined score of 123. That means a minimum score of 41 in each of the three sections, or as low as 37 in one or even two sections so long as you make up the difference in the rest of the exam. The test is given several times a year, and you can choose either paper or electronic format. Ample practice test materials are available with answer keys on the California State Teacher Credentialing website.
