DAT case studies
DAT · Put your knowledge to work in context.
The Dental Admission Test (DAT) is a standardized, multiple-choice admissions examination accepted by all U.S. dental schools and by select dental schools in Canada. It is designed to give dental education programs a standardized means of assessing an applicant's potential for success in dental school, and each school decides for itself how much weight to give DAT results alongside grades and the rest of the application. The test is delivered in English at Prometric test centers year round, including in U.S. The DAT case studies are 5 cases and about 3,812 words.
