Submit a Cancellation Request
If you are unable to attend your scheduled course, you must submit a cancellation request through your training manager. All course cancellations must be completed in CHRTAS and no other method is acceptable. All cancellations must be completed three (3) working days prior to the start of the course or you will be a "No Show". Failure to cancel is reported to your Chain of Command and will result in delay when resubmitting any future application. Thanks in advance for your cooperation and we look forward to seeing you in the future.
