Cancellation Policy
Applicants are allowed two (2) cancellations or “failures to appear” per application. However, a “failure to appear” without cancelling in advance will result in forfeiture of the examination fee (including the proctor fee) and an additional $80 fee to reschedule the examination. A second “failure to appear” without cancelling in advance in writing will result in forfeiture of the examination fee, the proctor fee and the closing of your application.
Examination fees are refundable for the first cancellation in advance of the examination. However, if the cancellation occurs eight (8) business days or fewer before the examination date, an $80 fee will be assessed for the first cancellation.
For the second cancellation in advance of the examination, an $80 fee applies regardless of when the examination is cancelled. If the cancellation occurs eight (8) business days or fewer before the examination date, the examination fee and proctor fee will be forfeited.
After a second cancellation, if you "fail to appear" for an examination, the examination fees, including the proctor fee, will be forfeited and your application will be closed. You will then have to re-apply and go through the application process again, if you wish to pursue your certification.
