Everything contractors ask us about the exam, the license, and the bundle. Where a number depends on current CSLB rules, we say so. Always confirm the official figures at the CSLB before you rely on them.

The California exam

6 answers

Two, and they're back-to-back on the same day. First is the Law & Business exam — everyone sits for that one, no matter the trade. Then comes a trade exam tied to your specific classification, say C-36 for plumbers or C-10 for electricians. The bundle gets you through both.

Three, really. Class A is General Engineering, Class B is General Building, and Class C covers the specialties — and there are 40-plus of those, everything from C-10 Electrical to C-36 Plumbing to C-39 Roofing. You apply for whichever one matches the work you're actually doing in the field.

The CSLB wants four years of journey-level experience in your trade, earned within the last 10. Time as a journeyman, foreman, supervisor, contractor, or owner-builder all counts toward it, and if you've put in schooling or an apprenticeship, that can knock out part of the requirement.

If labor and materials add up to $1,000 or more, yes — that job needs a CSLB license. Come in under that and you may fall under the minor-work exemption, but here's the catch: you still can't advertise yourself as a contractor without one. Cal. Bus. & Prof. Code §7048

Law & Business hits contracts, employment and payroll, licensing law, liens and bonds, safety, and the basic business-finance side of running a shop. Your trade exam is all codes, materials, methods, math, and trade-specific safety. Both lean hard on California rules and exact figures, and that's where most people get tripped up.

Yes — both are multiple choice, taken on a computer at an approved testing center. No hands-on portion, nothing to write out. What gets people is the wording: the questions are built to bait you toward the wrong answer, so a big part of prepping is just learning to slow down and read them right.

Exam day

6 answers

Right around 73% on each exam. We push you to an 80% readiness score on practice before we call you ready, because you want a cushion walking in — not to be sweating the last handful of questions.

Figure about 115 questions per exam against a fixed clock, so your pace matters as much as what you know. Running out of time is one of the most common ways people fail, and it's completely avoidable — which is why every practice test in the app runs on a timer.

It starts with the CSLB: you apply and get approved to test. Once you're approved, they send a notice telling you to schedule at an approved center near you. We don't book the exam for you — that part's between you and the board — but we make sure you walk in ready to pass it.

You only retake the one you didn't pass — not both. Expect a retake fee and a short waiting period before you can sit again. Drill the topics you missed, get your readiness score back to green, and reschedule. Plenty of people clear it on the second go.

A valid government photo ID and your scheduling notice. It's closed-book — no notes, no code book at your seat — which is exactly why you want those numbers committed to memory before you show up.

Since it's all computer-based, you'll usually know pass or fail before you walk out the door. Once you've cleared both exams, the last steps are posting your bond and paying the initial license fee.

The bundle

8 answers

Everything in one bundle: a physical flashcard deck for your trade, the Law & Business deck, printed study guides, and full app access on your phone or computer — adaptive practice tests, timed exams, and your live readiness score. See what's inside →

License schools still sell what they sold 20 years ago — classroom seats, DVDs, 300-page binders — and most of them charge five times what we do or more. License Ladder is adaptive and built around how you actually live: five-minute reps on the job, plain English instead of legalese, and a readiness score that tells you straight when you're ready. One $149 bundle, nothing carved out to upsell you later.

Right now we're live with General Building (B) and the Law & Business deck every applicant needs — both ready today. Residential Remodeling (B-2), Plumbing (C-36), and Electrical (C-10) are next, and those decks are in the works as we speak. More classifications follow as we keep building out the question bank.

Both — they come together, you're not picking one. The printed cards are there for when you'd rather be off your phone for a while; the app layers on adaptive practice tests, timed exams, and progress tracking. They pull from the same California question bank, so working one reinforces the other.

Yep. License Ladder Online is a web app that mirrors the mobile one — same cards, same practice tests, timed exams, and readiness score, right in your browser. One account, fully synced: run cards on your phone during the day, then pick up exactly where you left off on the laptop at the kitchen table that night. It's in the bundle, no extra charge.

No. App access is part of the one-time bundle price — no separate fee, no recurring charge.

Download your decks once and you can drill with no signal at all — on the truck, on site, anywhere reception drops out. Whatever you do offline syncs back up the next time you're connected.

Completely, and on purpose. We lead with the California rules — Cal/OSHA, CSLB classifications, state contract law — over the federal version anywhere the two differ, because the California rule is what the CSLB exam tests. Generic national prep gets these details wrong, and the exam punishes that.

Studying

5 answers

Most folks chip away at it in short sessions over a few weeks. There's no magic number — the app watches your readiness score and tells you when you've hit 80% card mastery and an 80% practice score. Once you're green, you're clear to schedule.

It rolls how well you know your cards together with how you're scoring on adaptive practice tests into a single number you can trust. It climbs from red through yellow to green as you sharpen up — so instead of guessing whether you're ready, you just look.

That's exactly how it's meant to be used. A few cards on a lunch break, in the truck, between calls — it adds up faster than you'd think. The app handles the rest, resurfacing the cards you've flagged and retiring the ones you've nailed. No marathon sessions required.

Built for exactly that. Every card is plain English, the legal and code material is pulled out of lawyer-speak, and the practice tests train you to catch trick wording before it costs you a point. You already know the trade — our job is getting you ready for the test.

The code book gives you everything — which is the problem. License Ladder zeroes in on what the exam actually asks and the exact numbers it tests, then drills them until they stick. Reading cover to cover is slow and easy to forget; an adaptive system that hammers your weak spots is what holds up under pressure on exam day.

Price & guarantee

5 answers

$149 right now during launch — it's normally $249. That's a single payment for the cards, the guides, and the app, all of it included. The old-school license courses run about five times that. See pricing →

It's a launch price, and it won't last. The product itself is finished and complete — we're just still growing the question bank — so early buyers get in at $149 and lock that rate, future updates included. Once launch wraps, it's back to $249.

No — one payment for the whole bundle: the physical cards, the printed guides, and full app access. Nothing recurring, ever.

Simple: study with the bundle, follow the plan, and get yourself to a green readiness score. Do all that and still don't pass? We refund you.

The printed cards and guides ship out to your address. You don't have to wait on the mail to get going, though — app access opens the moment you buy, so you can start drilling while the box is still in transit.

Applications & paperwork

8 answers

CSLB works applications in the order received and posts the live queue on its processing-times page. Lately, exam applications reach first review in about two weeks, and the final licensing step runs another three to four. Plan on three to six months end to end — more if your application bounces. Full timeline in the exam guide.

You’re in good company — CSLB says nearly half of all applications come back for corrections: blank fields, missing signatures, or experience forms that don’t cover the full four years. You get 90 days to fix and resubmit or the application is void and the $450 fee is gone. Write “N/A” in every box that doesn’t apply, sign in ink, and have your certifier check the experience dates twice.

A few narrow waivers exist: you passed the same exams within five years, you’re an immediate family member keeping a family business alive (active in it five of the last seven years), long-time listed personnel of a licensee, or an existing licensee adding a closely related classification. All discretionary, all audited. The breakdown lives in the exam guide.

Only five states: Arizona, Louisiana, Mississippi, Nevada, and North Carolina — Utah is not one, despite old articles. Your out-of-state license must be in good standing for five years, and reciprocity only waives the trade exam: everyone still takes California’s Law & Business exam. That’s the half the bundle drills hardest.

No — the application doesn’t ask, and you’re not required to volunteer it. CSLB runs your prints through the DOJ and FBI instead. A conviction only blocks a license if it’s substantially related to contracting and generally within the last seven years; dismissed or expunged convictions and arrests without conviction can’t be held against you at all.

Fail one exam and you retake only that one after a 21-day wait, paying the re-exam fee directly to PSI. There’s no limit on attempts — but there is an 18-month clock from when CSLB accepts your application to pass both, or you start over with a new application and fee.

Yes — ten exams now have official Spanish versions: Law & Business plus the B, C-8, C-9, C-15, C-27, C-33, C-36, C-39, and C-54 trade exams. If a Spanish version exists for your classification, you take it (rather than bringing a translator). CSLB’s Spanish study guides are free, and the whole License Ladder site runs in Spanish too.

Usually not yet — most solo contractors file an exemption. But five classifications must carry it even with zero employees: C-8 Concrete, C-20 HVAC, C-22 Asbestos Abatement, C-39 Roofing, and C-61/D-49 Tree Service. And mark the calendar: the everyone-must-carry-it law now takes effect January 1, 2028 (pushed back from 2026 by SB 1455).

Check out with the same email you'll use to sign into the app. Sign-in runs through Google, so use the address on your Google account. Get that right and the decks you bought unlock on their own the first time you log in. Slipped and used a different email? Just email support@licenseladder.com and we'll move your decks to the right account.

No. License Ladder is independent study material — we're not affiliated with, endorsed by, or sponsored by the Contractors State License Board or the State of California. For official requirements, always go straight to the CSLB.

People who know the trades and have been through California's licensing process themselves — built for contractors who'd rather be on a job than buried in a code book. The whole aim is to take the hard parts and turn them into something you can actually study between jobs.

Ask away. We'd genuinely rather answer an honest question up front than talk you into something that turns out to be the wrong fit.

Reach out and we'll point you to the exact deck, topic, or practice test for whatever's tripping you up. The system is built to keep showing you what to study next, so you usually won't be stuck for long anyway.
