Cancellation Policy

All cancellations must be reported to ATTI at least five (5) working days prior to the exam in question. 

Additionally, ATTI must be notified about substitutions to the roster at least two (2) working days prior to the exam. If you become aware of the need to cancel or reschedule after-hours, over the weekend or a holiday, feel free to leave a message in the ATTI voice mailbox at (602) 200-6780 or email

If cancellations, reschedules are not reported to ATTI in the time frames listed above no refund will be given, per our standard policy. Substitutions will not be accepted if they’re not reported at least two days prior to the exam. If you replace a technician without notifying ATTI in the required time frame, that technician will be turned away from the exam and you will forfeit the money you paid for that exam slot.
