Applications with incomplete or missing information will be considered unqualified unless the missing documentation can be provided within two (2) weeks of being notified (via telephone or email) that their application is incomplete. If the applicant fails to meet the qualification criteria for the exam, the exam fee (or the exam portion of a seminar/exam package fee) will be refunded minus a processing fee."
