The exam
What the California contractor Law and Business exam involves
Every applicant for a California contractor license must pass the Law and Business examination. It is administered by PSI Services for the Contractors State License Board (CSLB) at a PSI test center, and it is scored separately from the trade (classification) exam.
How many questions are on the California Law and Business exam?
The CSLB does not publish an exact scored-question count. Prep sources commonly describe the Law and Business exam as about 115 multiple-choice questions, and CSLB officially gives you 3.5 hours (210 minutes) to complete it. It is a closed-book, computer-based exam with four choices per question.
- Questions: about 115, multiple choice, four choices, one best answer (CSLB does not publish an exact count)
- Time limit: 3.5 hours (210 minutes), confirmed by CSLB
- Format: closed book, taken on a computer at a PSI test center
What is the pass mark for the California Law and Business exam?
The CSLB does not publish a fixed passing score. Its official guidance is that you are told the percentage of correct answers needed to pass at the test site, and that the percentage varies by examination. Any specific figure such as 72 percent that you see on prep sites is not an official CSLB number. Successful candidates are simply told they passed and are not given a detailed score.
What topics are on the California Law and Business exam?
The CSLB Law and Business Study Guide divides the exam into seven major sections with these approximate weights, and our mock exams and practice topics follow the same official blueprint.
- Business Organization and Licensing: about 13%
- Business Finances: about 15%
- Employment Requirements: about 20%
- Insurance and Liens: about 12%
- Contract Requirements and Execution: about 21%
- Public Works: about 5%
- Safety: about 14%
When does a California contractor license become required?
You need a California contractor license for any construction job where the combined cost of labor and materials is 500 dollars or more. Below that 500 dollar threshold the work may fall under the minor-work exemption, but splitting a larger job into smaller contracts to stay under the cap is prohibited.
How is the exam applied for, and can you retake it?
You apply to the CSLB, which charges an application fee (currently 450 dollars for one classification) that covers exam scheduling through PSI. After a failed exam you are generally eligible to retake it after 21 days, and your application stays valid for 18 months in which to pass both the Law and Business and the trade exams.

- 2026-07-06 Exam facts verified against primary CSLB and PSI sources across two independent AI research passes. Confirmed as official: the 3.5-hour (210-minute) time limit and the seven-section content blueprint with its topic weights.

Every question was cross-checked against its cited California statute by a second, independent AI model.
- 2026-07-06 Initial build from California public-domain statutes and regulations: 686 questions and 194 flashcards across all seven official Law and Business sections. The copyrighted CSLB reference book and any official examination questions were deliberately not reproduced.
FAQ
Common questions
Is this the official California contractor exam app?
No. This is an independent study aid and is not affiliated with or endorsed by the State of California, the Contractors State License Board (CSLB), or PSI. It is built from public domain California statutes and regulations.
How many questions are on the California Law and Business exam?
The CSLB does not publish an exact scored-question count. Prep sources commonly describe it as about 115 multiple-choice questions, and CSLB gives you 3.5 hours (210 minutes) to complete the closed-book exam.
What is the pass mark for the California Law and Business exam?
The CSLB does not publish a fixed passing score. Officially, you are told the percentage needed to pass at the test site, and it varies by exam. Figures like 72 percent that appear on prep sites are not official CSLB numbers, so our mock exams use an internal practice threshold, not a claimed official pass mark.
When do I actually need a California contractor license?
Once the combined cost of labor and materials on a job is 500 dollars or more. Splitting a larger job into smaller contracts to stay under that threshold is not allowed.
What topics does the app cover?
All seven official CSLB Law and Business sections at their official weights: Business Organization and Licensing, Business Finances, Employment Requirements, Insurance and Liens, Contract Requirements and Execution, Public Works, and Safety.
Does the app work offline?
Yes. Everything is stored on your device. There is no login and no internet connection is needed after you install it, so you can study anywhere.
Who writes these questions, and how do you check the answers are right?
Every question is written from California's public statutes and cites the section it comes from. Before it ships, a second, independent AI model from a different family confirms the cited statute supports the answer, and a human reviews anything the two models disagree on.
