FAQ - Advanced Dental Admission Test (ADAT)

Who should take the ADAT?

Take the ADAT if you are a:

  • Third- or fourth-year dental student interested in post-graduate training (e.g., in a dental specialty area)
  • Practicing dentist interested in post-graduate training (e.g., in a dental specialty area)
  • International dental student applying to advanced dental education programs or advanced standing in pre-doctoral programs
What is included in the ADAT?

The ADAT consists of multiple-choice test questions presented in English, and includes a battery of three tests: 

  • Biomedical Sciences (80 items)
  • Clinical Sciences (80 stand-alone and case-based items)
  • Data, Research Interpretation, and Evidence-Based Dentistry (40 items)
How do I apply to take the ADAT?

Start by reading the official ADAT 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
  • The ADAT Rules of Conduct

Once you have read the Guide, apply for the exam with your existing DENTPIN (the same DENTPIN you used to apply to dental school). You can also retrieve a lost DENTPIN.

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

Where do I take the ADAT?
The ADAT is offered at Pearson VUE Test Centers throughout the U.S. and Canada. It is available within designated testing windows. Please refer to the guide for more details. Once you have received your eligibility letter confirming that your test application has been accepted, you must contact Pearson VUE 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 Pearson VUE website to find a testing site near you, see updated COVID-19 procedures, and schedule your test. 
Can I get a fee waiver?

Fee waivers are now available. Application information is provided below.

In documented cases of severe financial hardship, a limited number of partial fee waivers are available to ADAT examinees each calendar year (January - December). The partial fee waiver covers 50% of the ADAT 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

To apply, download the 2023 financial information form (DOCX) complete and email it to 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 ADAT 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 an ADAT application online. Please allow up to 10 business days for review of all partial fee waiver requests.


Which programs accept ADAT?
More than 400 advanced dental programs require or accept ADAT scores. Consult the current ADAT Program List (PDF) to see how each program plans to use ADAT scores. If a program is not listed, they have not shared their intended ADAT use with the ADA. In that case, contact the program directly for more information. 

All programs have electronic access to ADAT scores. 
How do programs use the ADAT score?
Programs differ in how they choose to use the ADAT. Some supplement the scores with other information, while others only use ADAT results when required to break a tie between equally qualified candidates. Review the current 2023 Using the ADAT for Admission Purposes: A Guide for Advanced Dental Education Programs (PDF) for more information, including:
  • History of the ADAT
  • Evidence supporting the ADAT
  • Score scales and frequency distributions

Fairness considerations are embedded throughout the ADAT program, affecting every aspect of how this examination is constructed, administered, scored, and reported.  The Fairness document provided below shares additional details of interest:

Important note concerning periodontics terminology

In 2017, the American Academy of Periodontology introduced new classifications. Periodontal items now incorporate the new classifications for this examination. During the transition period, it is recommended that individuals become knowledgeable with both sets of classifications, because individual researchers, practitioners, and existing textbooks can communicate information using either set of classifications. Periodontal educators recommend that individuals refer to the following aids:
