CSLB Law and Business Practice Test

Practice questions for the California contractor Law and Business exam, organized by the seven official exam sections. Every answer is explained in plain English and cites the law or government guide it comes from.

How we make sure our answers are right

  • Written from public sources

    Every question is based on California law or an official guide from CSLB, EDD, IRS, DIR or Cal/OSHA. The explanation quotes the source and links to it, so you can check it yourself.

  • Checked blind before it goes live

    A separate AI reviewer answers each question without seeing our answer. If it picks a different answer, or the source does not support the answer, we rewrite the question or drop it.

  • Plain English

    Short sentences and common words, written for busy contractors and for people whose first language is not English. Legal terms are explained the first time they appear.

Frequently asked questions

What is the CSLB Law and Business exam?
It is a multiple-choice exam about business management and California construction law. To get a California contractor license, the qualifier must pass it, and usually also a trade exam for the license classification, unless CSLB grants an exam waiver. Source: CSLB: Get Licensed to Build.
What topics does the exam cover?
The CSLB study guide lists seven sections: Business Organization and Licensing (13%), Business Finances (15%), Employment Requirements (20%), Insurance and Liens (12%), Contract Requirements and Execution (21%), Public Works (5%), Safety (14%). CSLB says the percentages are approximate. Source: CSLB Law and Business Study Guide.
How many questions are on the exam, and what score do I need to pass?
CSLB does not publish them. Be careful with any website that says it knows the official passing score.
