Exams are specific to job types (civil service classification) and must be completed prior to submitting an application. A completed exam will determine your eligibility for the position. All State exams are labeled "bulletins" and can be found at
jobs.ca.gov. We've also linked to the relevant civil service examination in the job descriptions on this website so no need to go digging for examinations - just review the job description of the position you're applying for!
Note: The civil service exams aren't scary or complicated! In fact, the "examination" name is somewhat misleading. The examination asks a series of questions about your professional background to ensure you have the necessary training to thrive in the associated position. Low stress!
