Once you’ve assigned the fee waiver to a test taker, we automatically send an email notification to the test taker letting them know you have invited them to take a free DET in addition to prompting them to accept the offer and giving them instructions on how to apply this offer to their account. The student will have 21 days to take the test from the time they accept the offer. We recommend students utilize all of our free test prep resources in advance of taking the test to feel well prepared.
