The Electrical School
Novice to journeymen electrician, California edition: the ten-module curriculum, the state's real certification roadmap (DIR hours, exam blueprint, and costs), an Ohm's Law trainer, NEC sizing drills, and a 40-question quiz.
The California path, end to end
From "never touched a wire" to certified journeymen electrician. Items marked verified come from DIR's Electrician Certification Program (dir.ca.gov) or CSLB; general items are standard industry practice — confirm locally.
Phase 1 — Novice
Get ready to be hired
Finish your high school diploma or GED (most apprenticeship programs require one).
Get comfortable with algebra and basic geometry — aptitude tests for apprenticeships lean on them. Drill it right here in the platform: the Geometry Learning Lab (/geometry-lab) and the Mental Math Lab (/mental-math-lab). General practice tools, not official test prep.
general practice — verify with your local apprenticeship or AHJ
Get a driver's license and reliable transportation — job sites move.
general practice — verify with your local apprenticeship or AHJ
Get OSHA 10 (often OSHA 30 for supervisors) — it's standard jobsite safety training, and many employers and apprenticeships expect it before day one. It's a short online or in-person course you pay for yourself.

Phase 2 — Legal entry
Register before you touch wire
In California you may only perform electrical work for a C-10 contractor if you are a certified electrician, a registered electrician trainee, or an approved apprentice.
Register as an Electrician Trainee with DIR's Electrician Certification Program — trainees must be enrolled in a state-approved school while they work. DIR publishes the list of approved schools on the same site; pick one before you register, because enrollment is a condition of the trainee card.
Join an apprenticeship (IBEW/NECA, ABC, IEC) or work under a C-10 contractor as a trainee accruing supervised hours.

Phase 3 — Hours
Accrue supervised work experience
General Electrician: 8,000 hours (~4 years full-time) — the standard journeyman route.
Residential Electrician: 4,800 hours.
Fire/Life Safety Technician: 4,000 hours. Voice/Data/Video Technician: 4,000 hours.
Non-Residential Lighting Technician: 2,000 hours.

Phase 4 — Certification
Pass the state certification exam
General Electrician exam blueprint: Safety 6%, Preparation (theory, motors, circuit protection) ~22%, Installation 66%, Maintenance & repair 6% — Installation dominates, so study the NEC's wiring rules hardest.
Installation sub-topics include box & conduit sizing, conductor sizing, services & panelboards, clearances, overcurrent devices, lighting, motors, HVAC, fire systems, and special occupancies.
Schedule the exam through the testing vendor listed on DIR's Electrician Certification Program page (phone and internet scheduling are both listed there).

Phase 5 — Journeyman & beyond
Work certified — then maybe contract
Work as a certified journeymen electrician; keep your certification renewed with DIR on schedule (renewals are due roughly every 3 years — set a calendar reminder, working on an expired card is a problem).
Want to run your own jobs? A C-10 Electrical Contractor license from CSLB requires qualifying experience (four years of journeyman-level work is the standard) plus TWO exams — the trade exam and the Law & Business exam. Both must pass before the license issues; contractors pull permits; journeymen don't.
The C-10 extras: a CSLB contractor's bond (currently $25,000 — it rose from $15,000 in 2023 under SB 607) and workers' comp insurance once you have employees. Amounts and rules change — verify the current figures at cslb.ca.gov before you file.

What the path costs
Fee amounts change, so this lists what you'll pay FOR — not stale dollar figures. DIR and CSLB publish current fee schedules: check them before budgeting.
Electrician Trainee registration
One-time fee paid to DIR's Electrician Certification Program when you register.
Certification exam fee
Paid to the testing vendor when you schedule your exam.
Certification renewal
Due roughly every 3 years — renewal fees apply each cycle.
Apprenticeship tuition
Most IBEW/NECA-style apprenticeships are earn-while-you-learn: you're paid on the job, and tuition is typically none or minimal (verify with the specific program).
Tools & starter gear
A realistic first-year cost nobody budgets for: a CAT-rated meter, hand tools, PPE, and boots.
C-10 path extras
CSLB application and exam fees, the contractor's bond (currently $25,000 — verify, it has risen before), and insurance where required.
