The Dental Admission Test (DAT) is accepted by 66 dental schools in the U.S. and 10 in Canada. It is designed to provide dental education programs with a means to assess applicants’ potential for success. The test takes 4.5 hours to complete and is offered year round by Prometric test centers in the United States, its territories (including Guam, Puerto Rico and the Virgin Islands) and Canada.

• Candidates must wait 60 days between testing attempts on the DAT, with a maximum of four (4) such administrations permitted during any 12-month period of time. 
• Candidates with three (3) or more attempts on the DAT must apply for permission to test again, providing proof of recent application to dental school with each subsequent application to test.
• Subsequent to the candidate’s fifth DAT attempt, the candidate may retest only once per 12-month period.
• The DAT retest policy is not subject to appeal. 

All U.S. and Canadian dental schools require their applicants to take the DAT as part of the admission process. Each school uses its own criteria to determine how to weigh DAT results as part of admission decisions.

Prospective dental students should take the DAT during the second semester of their junior undergraduate year, or during the summer between junior and senior years. Make sure you have taken the subjects covered by the test, especially organic chemistry.

The DAT consists of multiple-choice questions presented in English, and includes a battery of four tests:

• Survey of the Natural Sciences (100 items)
• Perceptual Ability (90 items)
• Reading Comprehension (50 items)
• Quantitative Reasoning (40 items)

Start by reading the official DAT Candidate Guide, which explains:

• How the exam is constructed and scored
• How to prepare for the exam
• Eligibility requirements
• Fees and waivers
• How to schedule, reschedule, or cancel testing

Once you have read the Guide, apply for the exam with your DENTPIN. Your DENTPIN acts as your unique identifier. If you have not previously applied to a dental program, request your DENTPIN.

After your application has been processed, you will receive an eligibility letter that permits you to schedule your testing appointment.

The DAT is offered year-round at Prometric Test Centers throughout the U.S. and Canada. Once you have received your eligibility letter confirming that your test application has been accepted, you must contact Prometric to secure an appointment. We recommend doing this at least 60 to 90 days before your desired test date, since schedules fill up. Visit the Prometric site to find a testing site near you, see procedures updated for COVID-19, and schedule your test.

If you need to cancel or reschedule your appointment due to an emergency please contact the Department of Testing Services by emailing or calling 800.232.1694.

To reschedule or cancel a testing appointment, candidates must contact the Administration Vendor in advance of the testing appointment. The local test center cannot schedule, reschedule, or cancel your appointment. Additional fees apply, and must be paid directly to the Administration Vendor. Appointments must be canceled or rescheduled by the business day prior to the test (at least 24 hours in advance of the scheduled appointment). Candidates will receive a confirmation notification when rescheduling their testing appointment; please retain a copy of this confirmation.

All available fee waivers have been granted. The application for 2023 fee waivers will be posted at the beginning of next year. The following is for informational purposes only.

In documented cases of severe financial hardship, a limited number of partial fee waivers are available to DAT examinees each calendar year (January - December). The partial fee waiver covers 50% of the DAT fee. The partial fee waiver does not apply to any charges associated with rescheduling/canceling a test date or score reporting after the time of initial application. Partial fee waivers are granted on a first-come, first-served basis to eligible examinees who have submitted the required documents.

An examinee is eligible to request a partial fee waiver if each of the following criteria are met:

• First-time examinee
• Has not previously received a partial fee waiver
• U.S. citizen or resident alien
• Has demonstrated financial hardship
• Received financial aid from their school

When fee waivers are available, there is a form to submit with a copy of the financial aid award letter you received from your school. (The financial aid award letter cannot be older than 18 months.) Alternatively, applicants who have not been enrolled in a college or university in the past 18 months can substitute a copy of their most recent tax return. The DAT Program will review all partial fee waiver requests and make the final approval/denial decision. After the partial fee waiver request is reviewed, you will receive an email notification of the decision and instructions for submitting a DAT application online.Please allow up to 10 business days for review of all partial fee waiver requests.

Yes. Fairness in testing is of vital importance, and is in fact fundamental to an examination’s validity. Fairness considerations are embedded throughout the DAT program, affecting every aspect of how this examination is constructed, administered, scored, and reported.

The DAT tutorial is an online sample test. You can take it at any time.

The DAT program offers practice tests with questions written by actual DAT test constructors.

These practice tests feature the types of questions and question formats used in the actual test and will mirror the actual test specifications, although some modules/sections have fewer items than the actual test. The practice items are intended for the use of educators and students within the educational environment or for individual study and may not be reproduced in any format, whether paper or electronic, without expressed written permission of the ADA. This practice test should only be used as a personal resource when studying and preparing for an admissions examination. The number of correct answers will be reported upon completion of each module. Scores will not be provided. Applicants may choose between the following testing options:

• Individual modules, each available for $20.

• A full practice test, for the discounted price of $100.

Please note that changes to the DAT Biology Test Specifications (PDF) took place on January 21, 2022. Students taking the DAT on or after January 21, 2022 are encouraged to review the updated specifications, which include several new topics that were not previously covered on the examination.

Individual modules are $20 for each of the following topics:

Biology 101 (40 items) Organic Chemistry 101 (30 items) General Chemistry 101 (30 items) Reading Comprehension 101 (25 items) Perceptual Ability 101 (30 items)

Perceptual Ability 102 (30 items)

Perceptual Ability 103 (30 items)

Quantitative Reasoning 101 (40 items)

Once purchased, candidates will have 24 hours to access and complete the testing module. When the time expires, the test will end even if you are taking the test at that time.

The individual modules for DAT are identical to the modules included in the Full Practice Test, except that there are two additional modules provided for the Perceptual Ability Test that are not in the Full Practice Test.

The DAT Full Practice Test includes six modules ($100 for all six): Biology 101 Organic Chemistry 101 General Chemistry 101

Reading Comprehension 101

Perceptual Ability 101

Quantitative Reasoning 101

This test has an allotted time of 3 hours and 5 minutes, divided into timed sections to simulate the time constraints of the actual test. The practice tests do not include a break. Once you click “Begin Test” you must take the test in the allotted time.
