Why preparing properly pays off
The exam is closed book, so you have to know the rules, not look them up. And every failed attempt costs you time and money.
Wait after a fail
If you fail, you can retake the exam only after 21 calendar days, and you pay the re-examination fee again.
Deadline to pass
Your application is valid for 18 months from the day it is accepted. Miss it and you start over with a new application.
Closed-book exam
No reference materials are allowed. Multiple choice, four answers, one best answer. A calculator is provided.

What the exam covers
The official outline has seven sections. We weight practice the same way, so you spend your time where the points are.

Questions

Is this the official CSLB exam?
No. CA Contractor Exam is an independent study tool. We are not affiliated with or endorsed by the Contractors State License Board or PSI. To apply for a license and book the exam, use the official CSLB website.
Are these the real exam questions?
No, and anyone claiming to sell real exam questions should be avoided. Our questions are original. We write them from the official exam outline and public sources such as the Contractors State License Law, the California Labor Code, IRS Publication 15 and Cal/OSHA regulations.
Can I take the exam in Spanish?
Yes. CSLB offers the Law and Business exam and several trade exams in Spanish. Our practice material is available in both English and Spanish.
Does this cover my trade exam too?
Not yet. We start with the Law and Business exam, which most license applicants are required to take. Trade exams are planned next.
Are the questions up to date with current law?
Yes. Every question is written from the current statute, regulation or official publication, and each answer shows which one. California rules usually change on 1 January, so we review the affected questions every year and whenever CSLB updates the exam outline. The material is written for the exam itself, so for a real job on site always check the official source.
