DAT Quantitative Reasoning · Put your knowledge to work in context.
The Dental Admission Test (DAT) is the admissions exam accepted by all U.S. dental schools and select Canadian dental schools. It is designed to give dental education programs a means to assess an applicant's potential for success, and each school decides for itself how much weight to place on DAT results alongside the rest of the application. The test is delivered in English as multiple-choice items across four sections: Survey of the Natural Sciences, Perceptual Ability, Reading Comprehension, and Quantitative Reasoning. The DAT Quantitative Reasoning case studies are 5 cases and about 2,851 words.
