The Advanced Dental Admission Test (ADAT) emerges as a critical milestone for dental students eyeing post-graduate training, known as residency in the U.S., as well as foreign-trained dentists seeking admissions in advanced standing DDS/DMD programs in Canada or the U.S. This standardized examination evaluates candidates’ knowledge in biomedical sciences, clinical sciences, and evidence-based dentistry and is accepted by over 400 organizations . The ADAT is administered at Pearson VUE Test Centers across the U.S. and Canada. 

In this guide, we’ll explain the essentials of ADAT, from eligibility criteria to application processes, helping you confidently embark on your journey toward professional advancement.

    1. Biomedical Sciences (80 items)
    2. Clinical Sciences (80 stand-alone and case-based items)
    3. Data, Research Interpretation, and Evidence-Based Dentistry (40 items)

This comprehensive battery of tests evaluates candidates’ proficiency across crucial domains, ensuring readiness for the rigors of advanced dental education. The ADAT is available for administration during a fixed period each calendar year from March 1 through August 31.

How many times can I give ADAT in a year?

Normally, twice in the first year of Exam then once every year if you would like to improve the score. There is no limit to the number of attempts.


Embarking on your ADAT journey begins with thorough preparation and understanding of the application process. Here’s a step-by-step guide:

Three to four weeks after candidates complete the examination, scores are released. The range of ADAT scale scores is between 200 and 800. If you get a higher score in a specific area, it indicates that you have more advanced cognitive skills in that particular area. If you don’t take a test, you will get a score of 200.

How the ADAT score is calculated, based on the information provided in the ADAT User’s Guide

  1. Raw Score Calculation:

   – Each section of the ADAT consists of multiple-choice questions.

   – For each section, the number of correct responses is counted. Incorrect or unanswered questions do not contribute to the score.

   – This count of correct responses represents the raw score for each section.

  1. Scaled Score Conversion:

   – The raw scores for each section are converted into scaled scores using a formula provided by the ADA.

   – The purpose of scaling is to ensure fairness and consistency across different versions of the exam. It accounts for variations in difficulty between different sets of questions.

   – The scaled scores range from 0 to 100 for each section.

  1. Total ADAT Score Calculation:

   – The scaled scores for each section (Biomedical Sciences, Clinical Sciences, and Data, Research Interpretation, and Evidence-Based Dentistry) are combined to produce a total ADAT score.

   – The total score ranges from 200 to 800, with 500 as the mean and a standard deviation of 100. This means that the majority of test-takers will fall within one standard deviation of the mean (between 400 and 600).

   – The total score provides an overall assessment of the candidate’s performance across all sections of the exam.

  1. Percentile Ranks:

   – The ADA provides percentile ranks based on the total ADAT score.

   – Percentile ranks indicate the percentage of test-takers who scored lower than a particular candidate.

   – For example, a percentile rank of 70 means that the candidate performed better than 70% of test-takers.

Overall, the ADAT score calculation process involves converting raw scores into scaled scores, combining them to derive a total score, and providing percentile ranks for comparative analysis. This comprehensive scoring system ensures that candidates’ performances are accurately evaluated and standardized across administrations of the exam.

Do all 200 questions count and score?

The ADAT consists of 200 questions, but not all are used to calculate the examinee’s score. After the data is collected, these questions are analyzed for their statistical performance. If they meet the required standards, they may be included in future test forms to ensure up-to-date content. Candidates cannot differentiate between the questions affecting their score and those not.


Well the higher the better. However, in general any score above 500 is considered to be a decent one and scores above 600 plus is considered very competitive. Compare your score to the average and percentile ranks provided by the ADA. A score that places you above the average or in a high percentile rank is generally considered good. Compare your score to the average and percentile ranks provided by the ADA. A score that places you above the average or in a high percentile rank is generally considered good. Also it is wise to check the individual Program Requirements.

Is the average score fixed?

Nope. The average score changes every year based on the number of aspirants appearing and their scores. In 2023, 715 aspirants gave exams and the average ADAT Overall (ADAT) score was 486.0.


If you are aiming to score above 600 on the ADAT, it is crucial to approach your preparation with diligence, strategy, and effective test-taking skills. With my first hand experience of scoring 600 plus,  I can suggest following points plays a major role

  • Become familiar with the ADAT exam structure.
  • Create a comprehensive study plan.
  • Focus on weak areas.
  • Use high-quality study materials.
  • Practice time management.
  • Review test-taking strategies.
  • Simulate exam conditions.
  • Get feedback and support.
  • Stay consistent and persistent.
  • Prioritize self-care and well-being.

Does AFK & INBDE experience help?

Certainly, It does help if you planned properly. To maximize the impact of AFK/INBDE it is advisable to give these exams not after a long GAP. My personal suggestion would be to give AFK/INBDE First and within 2 months prepare and ace the ADAT.
