What is on the California Law and Business Exam?

Knowing the trade is not enough to run a construction business and manage large-scale construction projects. For this reason, the CA Law and Business Exam is a mandatory requirement for a California contractor license.

Running a contracting business demands more than technical skill. The CA Law and Business Exam is just as important as your trade exam because it verifies your understanding of California contractor business processes, laws, safety regulations, and more. It helps ensure you have the skills to manage employees and follow labor laws, as well as handle contracts and protect consumers.

California Law and Business Exam Overview

According to the requirements set by the Contractors State License Board (CSLB), this is what you should anticipate from the CA Law and Business Exam.

Who is the exam for: The exam is required for every contractor classification, including General Engineering (A), General Building (B), Residential Remodeling (B-2), and Specialty (C) contractors.
Format: Multiple-choice questions.
Closed-book exam

Important Things to Note About the Exam

Unlike many state contracting exams, California does not allow test takers to use textbooks or other reference materials. The CA Law and Business Exam, as well as the trade exams, are closed-book. Therefore, studying is paramount.

Some questions on the computer-based Law and Business Exam will ask you to solve mathematical problems. A digital calculator will be provided to you for the entirety of the exam.

It is in your best interest to answer every question since there is no penalty for guessing. Take your time and read each question and all four answers thoroughly before making your choice.

How to Prepare for the CA Law and Business Exam

To successfully pass this exam, students must grasp California contracting principles rather than simply memorize information. The following methods will help you prepare for the exam:

Begin your preparation by using the official CSLB study guide: The guide serves as your main study resource. The guide presents all the topics which will appear on the exam.
Use prep courses: Professional exam prep courses such as our California contractor courses serve as the preferred choice for many contractors because they offer organized learning paths and current information and qualified instruction.
Take practice exams: The process of taking tests multiple times will help you develop greater confidence. Find an exam prep course with an exam simulator that mimics the CA Law and Business Exam.
Focus on weak spots: Most contractors demonstrate better understanding in specific areas such as contracts and safety but struggle with subjects like accounting and labor law. Devote additional study time to the subjects which need the most improvement.
Set a study schedule: Don’t cram; rather, study your material through regular sessions that span multiple weeks instead of trying to learn everything at once.

Helpful reminder: Start early. Give yourself at least 4-6 weeks to prepare. It’s easy to underestimate the amount of material covered.
