Do I need to be certified to work as an electrician in California?

If you make connections of greater than 100 volt amps while working for a C-10 contractor, yes. That's how the Electrician Certification Unit states the rule.

Sole owners licensed in their own names are outside it, and C-7 and C-45 contractors working inside their own scope are outside it too. Everyone else on a C-10's payroll needs a card.

Is there a California journeyman electrician license?

No. California certifies individual electricians rather than licensing them as journeymen or masters, through the Division of Labor Standards Enforcement.

The closest thing to a journeyman card is the General Electrician certification, which takes 8,000 hours and a 100 question exam. The C-10 from the Contractors State License Board is a separate business level credential.

How many questions are on the California electrician certification exam?

It depends which of the five you're sitting. General Electrician is 100 questions in 4 hours 30 minutes. Residential Electrician is 80 in 3 hours 30 minutes.

Fire/Life Safety Technician, Voice Data Video Technician and Non-Residential Lighting Technician are each 50 questions in 2 hours 15 minutes. Those figures come from the Candidate Information Bulletin and the DIR test information page.

What score do I need to pass?

A minimum of 70 percent, on all five exams. The DIR test information page prints it as a minimum of 70 percent and the bulletin agrees.

On the 100 question General paper that's 70 marks, so you can afford 30 misses and no more.

Who gives the California electrician exam?

CPS HR Consulting delivers it through Pearson VUE for exams on or after June 1, 2026. The Electrician Certification Unit decides eligibility and the vendor delivers the paper.

Once you're eligible, an Authorization to Test email arrives from PearsonVUEConfirmation@e.pearson.com and you book your own seat. CPS HR answers at ecuexams@cpshr.us or 855-298-4917.

Can I bring my own code book to the exam?

No. The bulletin says you may not bring or use your own reference materials, because the books are supplied inside the testing system.

That means every tabbing and highlighting question people ask about other states' exams doesn't apply here. The bulletin prints no marking rules at all, because nobody's book comes through the door.

Which NEC edition is the California exam based on?

The 2023 edition. The bulletin lists NFPA 70, National Electrical Code, 2023 Edition among the references supplied on screen.

NFPA 70E 2024 and the Cal/OSHA Pocket Guide for the Construction Industry updated 2022 come with it, and three of the five exams add a further reference on top.

Which electrical code is in force in California right now?

The 2025 California Electrical Code, which is Part 3 of Title 24. It was published July 1, 2025 and took effect January 1, 2026.

It's built on the 2023 National Electrical Code, per the Building Standards Commission's own statement of reasons for that rulemaking. So the exam and the field are on the same model code year.

How much does the California electrician exam cost?

The application instructions print $175 for a single exam, $275 for two and $375 for three. The FAQ describes the $175 as $100 exam plus $75 administration, non refundable.

A re-test is $100 and a failure to appear is $100. Checks go to the DIR Electrician Certification Fund, and payments are neither refundable nor transferable.

How long do I have to take the exam after I apply?

One year from the date of your eligibility notice. The Division has to respond on eligibility within 30 days of receiving a complete application.

Sit early inside that year. If you fail at month eleven, the 60 day wait before a retest application pushes you past the window.

How soon can I retake it if I fail?

You wait 60 days from the day you took the exam before sending in the application for re-test, then pay another $100. The bulletin, the DIR test information page and the FAQ all agree.

Count from the day you sat it, not from the day the result arrived, and remember the 60 days runs before the paperwork rather than before the new date.

How many hours do I need before I can sit the General Electrician exam?

Eight thousand hours worked for a C-10 electrical contractor, under CCR Title 8 section 291.1. The hours have to cover two or more work areas and each area has its own ceiling.

Residential Electrician takes 4,800 hours, Fire/Life Safety and Voice Data Video take 4,000 each, and Non-Residential Lighting takes 2,000. The trainee route is described as 8,000 hours plus 720 hours of related and supplemental instruction.

What ID do I need at the test center?

Two forms of valid, original identification. Photocopies and digital IDs aren't accepted.

The primary has to be government issued with your first name, last name, a recognizable photo and a signature. The secondary has to be original and valid, showing your name plus either a signature or a photo. Both names have to exactly match the name you registered with.

Where are the California electrician exam test centers?

Neither the Candidate Information Bulletin nor the DIR test information page lists them. You pick a site inside the Pearson VUE scheduling system when you book.

The separate CSLB contractor exam does publish its cities, from Agoura Hills and Bakersfield through Sacramento, San Diego and San Francisco to Visalia and Walnut Creek, plus Wilsonville, Oregon.

Can I take the California electrician exam in Spanish?

The ECU FAQ says the exam is available in English and Spanish, and the application asks whether you want a Spanish language exam.

CCR Title 8 section 291.3 requires the exam in Spanish and other languages as practicable, and requires accommodations for disabilities on request. Ask on the application rather than on the day.

What happens if my certification expires?

You retake the exam. CCR Title 8 section 291.5 says an individual who allows certification to lapse has to retake the certification examination.

The renewal form prices that at a $200 exam fee, and the ECU fee page prices renewal of a lapsed or expired card at $200. Certification renews every three years and renewal applications have to be in 30 days before the period ends.

Is the C-10 exam the same as the electrician certification exam?

No. They're different exams from different agencies. DIR certifies individual electricians; the Contractors State License Board licenses the contracting business, and C-10 Electrical is its classification.

A C-10 applicant takes two exams, Law and Business plus the trade exam, and neither is the DIR certification exam.

How long is the C-10 exam, and is it open book?

Three and a half hours for each of the two examinations, and closed book. Reading materials and textbooks are prohibited items, along with phones, calculators, notes and food.

That's the opposite of the DIR exam, which supplies three references on screen. If you're sitting both, don't carry a habit from one into the other.

Does California use the 2026 NEC?

Not yet. The 2027 Triennial Code Adoption Cycle will adopt the 2026 edition of the NEC, and that becomes the 2028 edition of Title 24, effective January 1, 2029. Milestone dates for the cycle are listed as to be determined.

The exam's edition comes from the bulletin rather than from the code cycle, and the bulletin currently supplies the 2023 edition.

What happens if I miss my exam appointment?

A missed appointment can't be rescheduled and the fee is forfeited. Arriving late may also mean you're not admitted, with the same result.

Changes have to be made more than 48 hours before the appointment, and the bulletin works the example: an exam at 2:30 pm on July 3 has to be changed before 2:30 pm on July 1. The application instructions also print a failed to appear fee of $100.
