About Our Concord School
The CSLS Concord school is part of California's largest contractor license exam prep network. Since 1985, we've helped 200,000+ students pass their CSLB exam, 99% on the first try.
Our Concord location offers all four exam prep programs: All-Inclusive, Live Online, Crash Course, and Home Study Program. Whether you're preparing for a General Engineering (A), General Building (B), or any specialty C-classification, our instructors use the Mizener Method, a proprietary teaching approach built for hands-on learners, not academics.
Every student enrolled at this location can attend classes at any of our 25+ schools statewide. Start your classes here and attend a review session closer to home, or vice versa. Your enrollment travels with you.
