Do you offer "pass or no pay" or money back if I fail?
No. Contractors Classroom does not offer "pass or no pay" or money back if you fail. Our commitment is simple and honest: solid study material, a clear source for every answer, and support when you need it.
What we do instead: prepare you with practice questions and explanations on the topics the exam covers, each answer with a code or study-guide citation, plus a Practice Exam and a PSI-Style Exam mode so you can see your weak sections before exam day.
The exams are given by PSI for the Contractors State License Board (CSLB). CSLB develops the examinations with the assistance of industry experts and publishes a study guide for each exam that lists the topic areas and how each area is weighted. Our classroom sections follow those study-guide topic areas.

An online study and practice system for the California contractor license exams: the Law and Business exam that every qualifier takes, and the trade exams. It is a private study tool. It is not affiliated with, endorsed by, or part of CSLB or PSI.
Each course includes practice questions by section with an explanation and a citation for every answer, a Practice Exam and a PSI-Style Exam mode, a Learning Hub with lessons, trade Resources, an Application Tool that walks through the CSLB application steps, and the Classroom Helper study chat.

How long should I study?
There is no fixed number that fits everyone, and we will not invent one. A practical approach: work through every section of your trade and the Law and Business material until the explanations make sense to you, then use the Practice Exam and PSI-Style Exam results to find the sections you miss and go back to them.
CSLB gives applicants 18 months to pass the examinations, and CSLB says the basic study reference is the California Contractors License Law & Reference Book.

Who gives the exam, and how is it scheduled?
Testing is performed at PSI Exams. After CSLB accepts your application, you receive a Notice to Schedule an Examination, and you self-schedule each test and pay the exam fee directly through PSI. PSI has locations throughout the state and offers testing six days a week.
Test-takers receive their score results before they leave the test site. If you fail the Law and Business examination or your trade examination, you must wait 21 calendar days before retaking it. Examination results are good for five years.
No personal calculators, cell phones, or other electronic devices are permitted in the testing area. Pencils, scratch paper, calculators, and scale rulers are provided at the test center on request, and you must bring picture identification.

What does the exam cost? What does the license cost?
CSLB and PSI set and change their own fees, so we never quote them. CSLB publishes its complete fee list, and PSI charges the exam fee directly when you schedule. Our course price is on the pricing page.
