ADAT Practice Test

• The 2026 ADAT administration window runs March 1, 2026 through August 31, 2026 at Pearson VUE test centers. (source)
• The exam is 200 multiple-choice items across three sections: Biomedical Sciences (80 items, 95 minutes), Clinical Sciences (80 stand-alone and case-based items, 90 minutes), and Data, Research Interpretation, and Evidence-Based Dentistry (40 items, 45 minutes). Total administration time, including tutorial, optional breaks, and survey, is 4 hours 30 minutes. (source)
• The 2026 Examination Fee is $465, which covers administration and score reports to programs selected at the time of application. Additional score report requests are $55 each; candidates from non-CODA-accredited dental schools pay an extra $435 processing fee; the optional score audit is $105; rescheduling is $25. All fees are non-refundable and non-transferable. (source)
• ADAT results are reported as scale scores from 200 to 800 in 10-point increments. There is no official passing score — each advanced dental education program sets its own threshold. (source)
• A limited number of partial fee waivers (covering 50% of the Examination Fee) open on January 1 each year on a first-come, first-served basis for first-time examinees who demonstrate financial hardship. (source)
• Results post to the candidate's DENTPIN account and, if an advanced dental education program was selected at application, import into ADEA PASS within 3-4 weeks of the test date. (source)
• The ADAT is offered at Pearson VUE centers throughout the U.S. and its territories (including Guam, Puerto Rico, and the Virgin Islands) and at select Canada locations; it is no longer offered in Quebec. (source)
