The dental admission test (DAT) is one of the most important steps on the road to dental school. Your DAT score can open doors — or close them. Understanding what a good score looks like, how the exam is structured, and how to prepare strategically is essential for every pre-dental student.
This guide covers everything you need to know about the dental admission test: sections, scoring, percentiles, test dates, and the preparation strategies Dr. Jim Romano has used to help thousands of students succeed.
Students looking to improve their DAT score often begin with the DAT Destroyer and other concept-based DAT study materials before moving on to full-length practice exams.
What Is the Dental Admission Test?
The U.S. Dental Admission Test (DAT) is a standardized exam administered by the American Dental Association (ADA) for dental-school admissions. Candidates applying to Canadian dental schools should confirm whether each school accepts the U.S. DAT before applying to take it. The DAT measures your academic ability, scientific understanding, and perceptual skills — all areas critical to success in dental school.
The exam is computer-based and administered at Prometric testing centers. The ADA notes that most candidates complete two or more years of college before taking the DAT and encourages candidates to take it well in advance of the dental-school admission cycle. Plan your test date around your preparation and your target schools' deadlines.
DAT Exam Sections
The dental admission test consists of four main sections:
1. Survey of Natural Sciences (SNS)
100 questions | 90 minutes
- Biology (40 questions)
- General Chemistry (30 questions)
- Organic Chemistry (30 questions)
This is the most content-heavy section of the dental admission test. Biology covers cell biology, genetics, evolution, and anatomy. General Chemistry covers stoichiometry, equilibrium, acids and bases, and thermodynamics. Organic Chemistry covers reactions, mechanisms, and lab techniques.
2. Perceptual Ability Test (PAT)
90 questions | 60 minutes
- Keyholes
- Top-Front-End views
- Angle Ranking
- Hole Punching
- Cube Counting
- Pattern Folding
The Perceptual Ability Test (PAT) measures your spatial reasoning and visual perception — skills directly relevant to dentistry. Many students underestimate this section.
3. Reading Comprehension (RC)
50 questions | 60 minutes
Three reading passages on science topics with questions testing your ability to understand, analyze, and apply information. You do not need prior knowledge of the topics — everything you need is in the passage.
4. Quantitative Reasoning (QR)
40 questions | 45 minutes
The ADA lists algebra; data analysis, interpretation, and sufficiency; quantitative comparison; probability and statistics; and applied mathematics word problems for this section. QR is one of the five scaled scores included in your Academic Average (AA).
How Is the Dental Admission Test Scored?
The dental admission test uses a three-digit scoring scale ranging from 200 to 600 in 10-point increments. This reporting scale took effect on March 1, 2025. Two composite scores are:
- Academic Average (AA): The rounded average of the scaled scores in Biology, General Chemistry, Organic Chemistry, Reading Comprehension, and Quantitative Reasoning. PAT is not included.
- Total Science (TS): For the current scoring system, the rounded average of the scaled scores in Biology, General Chemistry, and Organic Chemistry.
A score of 400 is not automatically the national arithmetic average. In the ADA's published percentile table, AA 400 has a percentile rank of 54, while Total Science (SNS in that table) 400 has a percentile rank of 53. Scale scores and percentile ranks are different measures, and there is no official DAT passing score.
DAT Score Percentiles — What Do They Mean?
Understanding percentiles is helpful when interpreting your dental admission test performance. The following values apply specifically to Academic Average (AA):
| Academic Average (AA) | AA percentile rank in the ADA published normative table |
|---|---|
| 400 | 54 |
| 410 | 62 |
| 420 | 69 |
| 430 | 75 |
| 440 | 81 |
| 450 | 85 |
These are Academic Average (AA) percentile ranks from Table 2 of the ADA's published score-reporting document, updated January 29, 2025. They describe a national normative sample of more than 30,000 DAT attempts over a recent two-year period, not a newly calculated 2026 testing cohort. Use the appropriate column for Total Science (SNS in the ADA table), Biology, General Chemistry, Organic Chemistry, PAT, Quantitative Reasoning, or Reading Comprehension.
A percentile rank describes relative standing in the reference sample; it is not an admissions cutoff or a probability of acceptance. Each dental school determines its own acceptable scores.
What Is a Good Score on the Dental Admission Test?
A good score on the dental admission test depends on where you are applying. There is no official passing score and no single score that guarantees admission. Compare your individual section scores, AA, and TS with each target school's current published requirements and dated entering-class profiles. Use percentile ranks as context, not as a substitute for school-specific admissions information.
Keep in mind that your DAT score is one component of your application. Review your target schools' requirements for GPA, letters of recommendation, personal statement, shadowing hours, and interview performance. How these factors are evaluated depends on the school.
Dental Admission Test Dates — When Can You Take It?
The dental admission test is offered year-round at Prometric testing centers, subject to appointment availability. You apply through the ADA using your DENTPIN and schedule with the administration vendor after receiving eligibility confirmation.
You must wait 60 days between DAT attempts, with a maximum of four administrations in any 12-month period. Candidates who have taken the DAT three or more times must apply for permission to test again and provide proof of a recent dental-school application with each subsequent application to test. After the fifth attempt, a candidate may retest only once per 12-month period. Each new attempt requires a new application and examination fee.
There is no universal three-year admissions-validity rule stated in the ADA Candidate Guide. Check each target school's current score-age requirements and application deadlines. Official results are reported electronically within approximately three to four weeks of testing; if you have tested more than once, a history of all attempts is reported.
Plan well in advance of the dental-school admission cycle, allowing time for preparation, official score reporting, and a possible retake if appropriate. Completing the timed test sections takes 4 hours and 15 minutes; the full administration schedule totals 5 hours and 15 minutes, including the optional tutorial, scheduled break, and survey. Report to the test center at least 30 minutes before your scheduled appointment.
How to Prepare for the Dental Admission Test
Preparation is everything. The dental admission test is not a test you can cram for — it rewards students who build deep conceptual understanding over time. Here is the strategy Dr. Jim Romano recommends:
Start 4–6 Months Out
Give yourself enough time to cover all content areas without rushing. Most students study 20–30 hours per week during an intensive prep period.
Master the Content First
Before doing practice questions, make sure you understand the underlying concepts. The DAT rewards students who can apply knowledge — not just memorize facts.
Use the Right Materials
The DAT Destroyer is the gold standard for DAT preparation. It is harder than the actual exam by design — so when test day comes, the real questions feel manageable. Thousands of students have used the Destroyer to achieve competitive scores.
Practice Under Timed Conditions
The dental admission test is as much a time management challenge as a knowledge challenge. Practice full-length timed sections regularly in the final 4–6 weeks of your prep.
Join the Community
The DAT and OAT Destroyer Study Group on Facebook is one of the most active pre-dental communities online. Ask questions, share strategies, and learn from students who have already taken the exam.

Conclusion
The dental admission test is a challenging but very learnable exam. With the right preparation strategy, the right materials, and enough time, a competitive score is absolutely within reach.
Dr. Jim Romano began teaching and tutoring DAT students around 1985. The DAT Destroyer was first published in 2006. The DAT Destroyer series — including the DAT Destroyer, Math Destroyer, Organic Chemistry Odyssey, and General Chemistry Destroyer — is built on one principle: harder practice = easier test day.
