Illustration of the app's readiness dashboard.

You can build. The test is the problem.

You know the trade.
The test is a brand new game.

Dense legal text

Contracts, liens, indemnification: paragraphs written by lawyers for lawyers. We rewrite them in plain English so you actually remember them.

All kinds of tricks

Standardized tests bury the answer in wording designed to trip you up. We drill the patterns, so you spot the trap before it spots you.

Time-wasting sinkholes

You'd rather be earning, not sitting in night classes or rereading a binder. We built five-minute study bursts you can do on the truck, at lunch, or between jobs.

One bundle · Everything included

The cards, the guides, and the app, all working together. One box, one price: $89.

Buy once: $89 for the cards, the guides, and the adaptive app, all built on the same California question bank. The old exam schools charge five times that for binders and classroom hours.

Licensing Requirements

Qualifying for Multiple Licenses & Reciprocity

Topic: License application & license status

California law lets one person qualify for more than one contractor's license, but only if they hold a real financial stake in each business they qualify for.

Requirement: up to 3 licenses, 20% equity minimum
  • You can qualify for up to three separate licenses if you own at least 20% of each business you're the qualifier for.
  • This stops people from lending their license to a business they aren't really part of.
Adding a classification: a licensee adds one by:
  1. Applying to the CSLB for the added classification; and
  2. Passing the trade exam for that classification.
License reciprocity: California has agreements with certain states, so a contractor licensed in one may get licensed in the other without retaking the full exam.
  • Reciprocity states: Arizona, Louisiana, Mississippi, Nevada, and North Carolina.
Parallel questions: Q-574 · Q-578 · Q-597 · Q-598 · Q-600
Exam Tip

Remember the numbers: up to 3 licenses, 20% minimum equity in each business. Reciprocity: AZ, LA, MS, NV, NC.

Common questions

Common questions, straight answers.

The California exam

Two: the Law & Business exam, which every applicant takes, and a trade exam for your classification, like C-36 Plumbing or C-10 Electrical. You sit both the same day. The bundle prepares you for both.
You need roughly 73% to pass each exam. Our practice tests target an 80% readiness score so you walk in with margin to spare.
Each exam is multiple choice, roughly 115 questions, taken under a time limit.
CSLB generally requires four years of journey-level experience in your trade within the last 10 years. Apprenticeship, schooling, or running your own crew can count toward it.
California issues three: Class A (General Engineering), Class B (General Building), and Class C (Specialty), with 40-plus C classifications like C-10 Electrical and C-36 Plumbing.
In California, work where labor and materials total $1,000 or more generally requires a CSLB license. Smaller jobs may fall under the minor-work exemption, but advertising rules still apply. Cal. Bus. & Prof. Code §7048
After you apply, expect roughly six weeks to be cleared to test, then you schedule your exam date. How fast you pass is the part you control, and the part we help with.

The bundle & studying

A physical flashcard deck for your trade, the Law & Business deck, printed study guides, and full access to the mobile app with practice tests, timed exams, and your readiness score. See what's inside.
The license schools sell classrooms, DVDs, and 300-page binders — the same methods they used 20 years ago — and most charge five times our price or more. License Ladder is an adaptive system built for how you actually live: five-minute bursts on the job, plain English, a readiness score that tells you when you're ready, and one $89 bundle with nothing held back for an upsell.
General Building (B), Residential Remodeling (B-2), Plumbing (C-36), and Electrical (C-10), plus the Law & Business deck that every applicant needs.
Yes. We prioritize California rules, Cal/OSHA, CSLB classifications, and state contract law over federal where they differ, because that is what the CSLB exam tests.
Most people study in short bursts over a few weeks. There is no fixed number, because the app tracks your readiness score and tells you when you have hit 80% card mastery and an 80% practice score, which is your signal to schedule.
That is the point. The app is built for five-minute bursts on a lunch break, in the truck, or between calls. Carry the physical cards when you would rather be off your phone.
Download your decks once and drill without a signal. Your progress syncs the next time you are online.

Study the bundle, reach a green readiness score, and if you do not pass, we refund you.
