NASCLA in California
California is one of the 18 jurisdictions that accept the NASCLA Accredited Commercial General Building Contractor Examination — here's exactly what that gets you, and what it doesn't.
How California accepts it
Accepted case-by-case by the CSLB since April 2025, and only for applicants who have held an out-of-state contractor license for at least 5 years — confirm current policy before applying.
Accepting agency: Contractors State License Board (CSLB). Acceptance policies can change — always verify with the agency before you apply.

With roughly two dozen references allowed at your desk, this is a book-navigation exam. Tab your books, drill lookups against the clock, and the 5.5 hours is plenty — that's the Tab & Pass method.
