Training Examination Review
Cancellation of a training course registration and transfer to another course within the same calendar year will be honored provided written notification is received by the Institute office via e-mail or mail no later than ten (10) business days before the first day of the scheduled training course. If cancelling a training course registration and not transferring to another course within the same calendar year a $250 cancellation fee will be assessed. A $500 administrative fee will be charged for cancellations received less than ten (10) days from the start date of the registered training course. Please contact the Vibration Institute staff directly regarding discounts for multiple registrations from the same organization. No-shows for the course will not receive a refund. There are additional cancellation fees applied for exam cancellations.
