Candidates may change a scheduled test date and/or test time to another date/test time within the same testing interval. Candidates do not need to contact ONCC to change the date or time of a test appointment as long as the change is made within the same testing interval.

If you need to change your 2008 test appointment to another day/time within the same testing interval, you must do so at least 24 hours prior to your scheduled appointment. Follow the instructions on your Authorization to Test (ATT).
