The NASCLA exam in California

Bid Bond editorial teamUpdated 3 min read

The California Contractors State License Board (CSLB) is on NASCLA's list of agencies that accept the NASCLA Commercial General Building exam. In California the exam matters mainly to contractors already licensed in another state. Here is what CSLB's own site says and what NASCLA's list adds.

What CSLB's site says

CSLB's page for contractors who already hold a license from another state or country, read 7 November 2026, says:

  • You cannot use a contractor license from another state to work in California. You need a California license.
  • If you have taken and passed the NASCLA commercial exam and have been licensed for at least five years in good standing in another state, you may be able to get a trade exam waiver.
  • For its reciprocity program, CSLB says it may waive the trade portion of the exam but keeps the right to require it, and the applicant still takes the California Law and Business exam and meets all other licensure requirements. The page does not say in so many words whether that also applies to the NASCLA waiver, so ask.

What NASCLA's list adds

NASCLA's listing for CSLB says that as of April 25, 2025, the California B General Building trade exam may be waived for an applicant from out of state who has held a license in good standing in that state for at least five years and has passed the NASCLA exam. It also says that California residents must take the California trade exam. We did not find the residents point on CSLB's own page, so confirm it with CSLB.

NASCLA's map on its participating agencies page, read 7 November 2026, shades California as an accepting state, not an administering one. NASCLA's page describes the choice between a state's own trade exam and the NASCLA exam only for administering agencies.

Where to apply

CSLB's application steps start on its Applicants page.

Before you book

  • Confirm with the agency. Ask CSLB whether you qualify for the waiver, whether it covers the B classification you want, and whether the residents rule on NASCLA's list applies to you. Ask which license classification it accepts the NASCLA exam for, what else you need, and how recent your exam date must be.
  • NASCLA comes first. NASCLA must accept your application at ned.nascla.org before you can book with PSI. Approval gives you one year and up to three attempts. See cost, scheduling and retakes.
  • Send a transcript. After you pass, you buy a transcript in NASCLA's National Examination Database (NED) and send it to the agency. See how to apply and use NED transcripts.

For the other participating states, see which states accept the NASCLA exam. To weigh the NASCLA exam against a state's own trade exam, read NASCLA exam vs a state trade exam.
