Skill-Builder Classes

Additional Contractor Classes

Targeted classes that go beyond the basics, letting you add a new CSLB classification, master the construction math your exam expects, and learn the test-taking strategy that turns preparation into a passing score.

More Than Exam Prep

Passing the CSLB exam (and building a license that grows with you) takes more than memorizing facts. Sometimes you need to brush up on the construction math the trade exam expects, learn how to take the test under pressure, or add a brand-new classification to a license you already hold.

That’s what these classes are for. Each one is focused on a specific goal, taught by the same instructors who have helped 200,000+ California contractors pass over 40+ Years in business.

Choose the class that fits your goal below, or call us at 800-809-6463 and we’ll point you to the right one.

Common Questions

Additional Contractor Classes Questions

These are focused, skill-building classes that go beyond a single exam-prep program. They help already-licensed contractors add a new classification, sharpen the construction math their trade exam expects, and build the test-taking strategy that helps you pass with confidence.
It depends on the class. Adding an additional classification is for contractors who already hold an active CSLB license. The construction math review and test-taking skills classes help anyone preparing for the CSLB exam, whether it is your first license or your next one.
Yes. The CSLB trade exam includes a construction-math and estimating component, and a big part of passing is simply knowing how to approach the test. Our math review and test-taking classes target exactly those areas so you walk in prepared.
Generally no. A contractor who already holds an active license and is adding another classification typically does not need to retake the Law & Business exam; the focus is on passing the new trade’s exam. Call us and we will confirm what applies to your specific license.
