Good preparation includes knowing how to move from the question to the correct book, finding information quickly, and avoiding spending too much time on one question.

After passing the exam, applicants must continue through the Arizona Registrar of Contractors licensing process. This may include submitting required forms, meeting experience requirements, identifying the qualifying party, providing business information, satisfying bonding or financial responsibility requirements, and meeting any other requirements set by the state. Passing the exam is important, but it does not replace the state application or guarantee license approval.

State Requirements

Arizona contractor licensing is administered by the Arizona Registrar of Contractors. The state issues contractor classifications tied to specific scopes of work, and applicants should make sure they pursue the correct license classification before beginning the licensing process.
