California Contractors State License Board Exam Overview
CSLB Contractor License Exam

Trade Exam + Law & Business Exam

The CSLB licensing exam is taken in two separate parts: your trade-specific exam and the Law & Business exam. After CSLB approves your application, your application information is sent to PSI so you can schedule your exam date.

Two Separate Exam Parts

You must complete both parts required by CSLB. Each exam is scheduled and paid for separately through PSI.

Trade Exam

Trade-Specific Knowledge

The trade exam focuses on the classification you are applying for, such as general building, electrical, plumbing, concrete, roofing, or another CSLB trade.

  • Approximately 120 multiple-choice questions
  • Tests your trade knowledge and practical work experience
  • Scheduled after CSLB approves your application
Law & Business Exam

Business and Contractor Law

The Law & Business exam covers California contractor rules, business management, contracts, safety, labor, and legal responsibilities.

  • Approximately 116 multiple-choice questions
  • Required for most CSLB license applicants
  • Separate from the trade exam

How Scheduling Works

PSI works directly with CSLB and operates many of the exam locations used by contractor license applicants.

Submit Your CSLB Application

CSLB reviews your contractor license application and determines whether you are approved to test.

CSLB Sends Your Information to PSI

Once approved, your CSLB application number is sent to PSI so the exam company can help you schedule your test date.

Schedule Your Exams With PSI

You schedule the Trade exam and the Law & Business exam separately at an available PSI testing location.

Pay the Exam Fee

Each exam costs about $53. If you are taking both parts, expect to pay for each one separately.

If You Do Not Pass

If you fail either the Trade exam or the Law & Business exam, you must wait 21 calendar days before scheduling another attempt. You will also need to pay the exam fee again for the exam you are retaking.
