The Dental Admission Test (DAT) is the standardized exam that all U.S. dental schools require applicants to take as a component of their admission process, and it is also accepted by select dental schools in Canada. Programs use it to assess an applicant's potential for success in dental education, and each school decides for itself how much weight to give the results. The test is delivered in English as multiple-choice items across four sections: Survey of the Natural Sciences (100 items), Perceptual Ability (90 items), Reading Comprehension (50 items), and Quantitative Reasoning (40 items). Topics on this exam: Survey of the Natural Sciences, Perceptual Ability, Reading Comprehension, and Quantitative Reasoning. The DAT PAT case studies are 5 cases and about 2,201 words.
