Pre-approval of your licensing application is required. For pre-approval, applicants must:

Upon receiving an approval letter, the applicant will need to:

    • make an appointment with a registered Test Center to take the exam - additional testing fees established by each CBT center may apply.
    • some test centers do not offer fee refunds.

Retesting by CBT after failing a written test is allowed, so long as your application is in an approved status.
