If any items are missing, the applicant will be notified, usually via email, that the application cannot be processed until all required items are received.

If all items are received, the applicant will receive an approval letter via email or postal mail that they have been scheduled for the next available exam date and to appear before the Advisory Council (typically the same morning as the exam).  The letter will advise them of the time, date, and location of the exam/meeting.  (See “Testing Dates and Procedures.”)

The applicant must achieve an exam score of 60% or more to be approved for registration.  If this score is achieved, the applicant will be instructed to wait after the exam for the council meeting.  Their attendance at the meeting will include a brief interview with the Council, after which the applicant will receive their registration number.  Registration certificates and wallet cards are usually mailed out by the following business day.
