AADSAS will automatically match your scores within the first few days of opening your application. Make sure the dentpin you give AADSAS matches the one you used to register for the DAT. AADSAS will distribute them to all the schools you apply to IF you have selected at least one AADSAS school when registering for your DAT.
Additionally, when you select dental schools on your DAT application that participate in a standardized application service (ADEA AADSAS or TMDSAS), the Department of Testing Services will report your official scores to the application services. If your DAT application has no dental schools selected, then you have not granted permission to the Department of Testing Services to release your official scores and your official scores will not be forwarded to the standardized application services.”

It is always recommended to check every box on the page when applying to take the DAT because it is free the first time around. Checking at least one school that participates in AADSAS meets the requirements and forwards your score to the centralized server. Sending score reports afterwards are $33 dollars per school.
You will have to pay for a score report so that it appears on your AADSAS. The DAT score needs to be on the application when its sent out to dental schools.

If you did not already send your DAT scores to the school you end up attending, you MAY have to pay to have your DAT scores sent there once admitted. This can vary from school to school.
