About LBExam

Why it exists

Most practice tests for this exam are quizzes with no sources behind them. Get a question wrong and you are told the letter, not the rule, with no way to check whether the rule was ever right. That matters more on this exam than most, because the exam is closed book.

So we built this one the other way round. The law comes first, the questions are written from it, and most answers link straight to the section they come from, here on the site. It is for anyone sitting the California Contractor Law and Business Exam, first time or retake, in any classification, because everyone sits this paper.

How the work is checked

We write every question and article on this site from the public sources cited beside it: the Business and Professions Code, the regulations, the CSLB's own rules and the courts' published decisions. Nothing here comes from a course book, someone else's question bank, or memory. Before a question goes live we check it against the source, then go back and check it again with the draft out of sight, working from the cited section alone. If it does not hold up, it is fixed or it goes. Where an answer rests on the law, it links to the section, reproduced here, so you can read it yourself rather than take our word for it. If you spot a mistake, tell us and we will put it right as quickly as we can.

Of the questions themselves: Most carry the provision they rest on, as a link into the law on this site. The others are written from a standard form or a published guide, which is not law and is not reproduced here, so they carry the explanation alone.

The sources page lists every document the questions rest on.

Independence

LBExam is independent and not affiliated with the Contractors State License Board.

Contractors State License Board and CSLB name a California state agency. They appear here only to describe the exam.

LBExam has nothing to do with the Contractors State License Board. They run the exam; we help you get ready for it.

Privacy

We store as little as we can: your email address, your answers, and whether you have paid. No ads, and we do not sell your data. Your card number never reaches us, and nothing here identifies you to CSLB. Details on the privacy page.

Also from the same team

LBExam is one of the Blackletter sites. The idea is the same on each: every question written from the statute, the section beside the answer. DealerPrep does it for Ontario's OMVIC dealer and salesperson exam. BrokerExam does it for the RIBO Level 1 broker exam. OriginatorExam does it for the NMLS SAFE mortgage loan originator test. IrrigatorExam does it for the Texas Landscape Irrigator exam. This site does it for the contractor Law and Business exam, where the law runs across four California codes and nothing comes into the room with you.
