If a veteran withdraws from a course after the end of the drop period, he or she may have to repay all benefits for the course unless it can be shown that the change was due to mitigating circumstances. VA defines "mitigating circumstances" as unavoidable and unexpected events that directly interfere with the pursuit of a course and are beyond personal control.
Special Note: TCC offers sessions referred to as "accelerated sessions" by the Department of Veterans Affairs (DVA). This means the DVA will accelerate pay status in proportion to the rate of the accelerated sessions. For this reason, veterans should check with the TCC Veterans Affairs Office to be sure of the actual rate of acceleration.
If a veteran withdraws from one or more of courses after the end of TCC drop period, VA will reduce or stop benefits on the date of reduction or withdrawal.
