What Is the California Electrician Certification?
The Electrician Certification is the full license issued by California's Division of Industrial Relations (DIR) to work as a qualified electrician. Unlike the ET card — which lets you work as a supervised trainee — the certification means you can work independently, bid on jobs, and supervise other trainees.
To earn it, you need to complete an approved training program, accumulate 8,000 hours of on-the-job experience, and pass the California Electrician Certification Exam.
Requirements to Get Certified
The DIR requires all three of the following before you can sit for the certification exam:
Complete an Approved Training Program
You must finish a DIR-approved electrician trainee program covering electrical theory, the NEC code, and California electrical laws. CET's program is fully approved and self-paced — 10 months to 2.5 years.
Accumulate 8,000 OJT Hours
You need at least 8,000 hours of on-the-job training working under a certified electrician. With full-time work, this takes approximately 4 years. During this time you earn a real wage as a paid trainee.
Pass the California Electrician Certification Exam
The state exam is administered by DIR and covers the National Electrical Code (NEC), California amendments, and trade theory. You can take it once you meet the training and OJT hour requirements.
The California Electrician Certification Exam
The certification exam is a multiple-choice test administered by the DIR. It covers:
- The National Electrical Code (NEC) — wiring methods, grounding, overcurrent protection
- California electrical laws and DIR regulations
- Electrical theory — Ohm's Law, AC/DC circuits, transformers, motors
- Load calculations and blueprint reading
CET offers continuing education courses designed to help you prepare for and pass the state exam, including the NEC code book course and exam prep materials.

Renewing Your Electrician Certification
Once you're certified, you must renew every 3 years. Renewal requires completing 32 hours of DIR-approved continuing education (CEUs). The 32 hours must include specific required topics:
- 8 hours — California electrical laws and regulations
- Remaining 24 hours — any approved electrical CEU topics
