Q: What is transcript verification and why is it done?
A: After AADSAS receives all of your official transcripts, the information you provide in the Coursework section will be audited for accuracy. Accuracy is important in this section because this is the basis for academic information provided to the dental schools, including coursework summaries and GPA's.
If, during the transcript verification process, relatively minor differences are noted, your course titles, course numbers, grades or credit hours earned will be changed to reflect the accurate information. Changes made by the AADSAS Transcript Processing Department will be noted on both your application information and on the information sent to dental schools.
When major discrepancies between the information you provide in the Coursework section and your official transcripts are noted, you will be contacted by a staff member in the AADSAS Transcript Processing Department via email. Your application may be returned to you for revision and resubmission.
