Updated October 10, 2026: DAT scoring, conversions, percentiles, and retesting guidance reviewed against official ADA documentation.
If you're a pre-dental student preparing for or recovering from test day, congratulate yourself on being part of a small, elite pool of individuals chasing a dental career.
Many students still search for terms like "20 DAT percentile" or "21 DAT score percentile," even though the scoring system has changed. This guide explains both the old and new DAT scoring scales.
If you're new to the DAT, start with our full guide: What Is the DAT Exam? When Should You Take It and How It's Scored.
If you're trying to understand how your DAT score percentiles are calculated or what a specific percentile actually means, this guide breaks it down clearly.

DAT Score Conversion: Understanding the New 3-Digit Scale
But one big question comes up after every test: What do my DAT score percentiles really mean? Many students look only at their scaled scores. Published percentile ranks provide context about relative standing in a national reference sample. Understanding these numbers can help you interpret your performance and set realistic goals for admission.
Students preparing for the exam often review DAT score percentiles while planning their study schedule and choosing the right DAT study materials.
This updated guide explains the new 200-600 scoring system, percentiles, and what good scores look like in the current DAT testing cycle.

Overview of the DAT Exam
The U.S. Dental Admission Test (DAT) is a standardized examination used for dental-school admissions. Candidates applying to Canadian schools should confirm each school's acceptance of the U.S. DAT before applying to take it. The exam measures academic ability, scientific understanding, and perceptual ability across four major sections:
- Survey of the Natural Sciences (Biology, General Chemistry, Organic Chemistry)
- Perceptual Ability (PAT)
- Reading Comprehension (RC)
- Quantitative Reasoning (QR)
In addition to individual scores, students receive a Total Science (TS) and Academic Average (AA). AA is the rounded average of Biology, General Chemistry, Organic Chemistry, Reading Comprehension, and Quantitative Reasoning scaled scores, excluding PAT. Under the current scoring system, TS is the rounded average of Biology, General Chemistry, and Organic Chemistry scaled scores.
The New DAT 200-600 Scoring Scale (Effective March 2025)
What Is the Highest DAT Score on the DAT?
The highest possible DAT score is 600 under the current DAT scoring system introduced in 2025.
The DAT now uses a 200–600 scale:
- 200 = Lowest reported score
- 400 = AA percentile rank of 54 in the ADA published table
- 600 = Highest possible score
A score of 600 is the maximum reported scaled score. It does not establish that every question was answered correctly. The ADA uses psychometric equating procedures, and some questions are experimental and unscored.
While many students focus on achieving the highest DAT score possible, schools may evaluate applicants using factors beyond the DAT. A strong GPA, science GPA, shadowing experience, research, extracurricular activities, and letters of recommendation may play a role, depending on the school's criteria.
The ADA replaced the 1–30 reporting scale with a three-digit DAT scoring scale of 200–600 in 10-point increments effective March 1, 2025.
- 200 = minimum reported score
- 600 = maximum reported score
- 400 = AA percentile rank of 54 in the ADA published table
DAT results are scale scores, not raw totals or percentile ranks. The ADA uses psychometric equating to account for differences among examination forms and does not publish a universal number-correct-to-scaled-score conversion. Candidates are not penalized for guessing. Some questions are experimental and are not scored.
Students preparing for the exam often rely on high-quality DAT study materials to practice with problems that reflect the difficulty and style of the real DAT.
DAT Academic Average Conversion Chart (Old vs. New)
The following values are specifically for Academic Average (AA). The old-to-new values come from Table 1 of the ADA's published concordance document. The percentile column gives the Table 2 rank of the approximately equivalent new AA score; it is not a separate historical percentile for the old score. Individual subjects and Total Science use different concordance and percentile columns.
| Old Academic Average (AA), 1–30 scale | Approximately equivalent new AA, 200–600 scale | New AA percentile rank in the ADA published normative table |
|---|---|---|
| 17 | 370 | 32 |
| 18 | 390 | 47 |
| 19 | 410 | 62 |
| 20 | 420 | 69 |
| 21 | 440 | 81 |
| 22 | 460 | 88 |
| 23 | 470 | 91 |
| 24 | 490 | 96 |
| 25 | 510 | 98 |
| 26 | 520 | 99 |
| 27 | 540 | 100 |
| 28 | 560 | 100 |
| 29 | 580 | 100 |
| 30 | 600 | 100 |
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.
The ADA table is a comparison between reporting scales, not a raw-question conversion chart. Values shown as 100 in the percentile table are published percentile ranks, not proof that every other candidate scored lower.
Common DAT Scores and What They Mean
What Does a 20 DAT Score Mean? (Old Scale vs New 3-Digit Scale)
If the old score is Academic Average (AA) 20, the ADA concordance gives approximately AA 420. In the published new-scale AA percentile table, 420 has a percentile rank of 69. A score of 20 in an individual subject must be interpreted using that subject's column. This rank does not establish an admissions cutoff.
What Does a 21 DAT Score Mean?
An old AA 21 corresponds approximately to AA 440, whose published AA percentile rank is 81. Use the appropriate subject-specific column if 21 refers to a section score rather than AA.
What Does a 22 DAT Score Mean?
An old AA 22 corresponds approximately to AA 460, whose published AA percentile rank is 88. School-specific requirements and the rest of the application still matter.
What Does a 19 DAT Score Mean?
An old AA 19 corresponds approximately to AA 410, whose published AA percentile rank is 62. This is above 400 on the new AA scale, not below it. Individual-section concordance values may differ.
DAT Score Percentiles (2026 Explained)
DAT percentile ranks show relative standing in the ADA's national reference sample. They are specific to the score type and the published table.
- Percentile rank 90: About 90% of attempts in the reference sample received that score or lower.
- Percentile rank 50: About 50% received that score or lower. This describes relative standing, not the arithmetic mean.
- Percentile rank 21: About 21% received that score or lower, with approximately 79% higher.
How to Determine Your DAT Score Percentiles (Simple 2026 Method)
To find the published percentile rank associated with your DAT scaled score:
- Look at your scaled score (the 200-600 number on your score report).
- Check the ADA's current percentile chart, which lists percentile ranks for each score type in its national normative sample.
- Match your AA, TS (SNS in this table), or individual score to the correct percentile column.
Example: An AA 480 has a published AA percentile rank of 94. About 94% of attempts in the ADA's reference sample received AA 480 or lower. The same number in another score column can have a different percentile rank.
Important: The ranks cited here are from the ADA document updated January 29, 2025. Check the ADA for newer published norms; this document does not establish a guaranteed annual recalculation schedule.
What Does a 21st Percentile on the DAT Mean?
A percentile rank of 21 means about 21% of attempts in the reference sample received that score or lower, with approximately 79% higher. It is below the 50th-percentile position, but whether to retake depends on your target schools' requirements and your preparation.
Is 21st Percentile on the DAT Good?
A rank of 21 is below the 50th-percentile position in the reference sample. It does not by itself determine admission or establish a required retake. Compare the underlying scaled score and score type with your target schools' current requirements.
Why Students Get Confused
A percentile rank of 21 is not an old AA score of 21. An old AA 21 corresponds approximately to new AA 440, which has a published AA percentile rank of 81. Always identify whether a number is a scaled score or a percentile rank.
Percentile ranks provide context for scaled scores. They do not reveal a school's admissions weighting or substitute for its current requirements.
What Is a Good DAT Score in 2026?
There is no official passing score. Each school determines acceptable scores. For context, the following are published AA percentile ranks, not school-admission categories:
| Academic Average (AA) | AA percentile rank in the ADA published normative table |
|---|---|
| 400 | 54 |
| 440 | 81 |
| 460 | 88 |
| 480 | 94 |
| 500 | 97 |
| 540 | 100 |
Use each target school's current requirements and dated class profiles to decide what score to aim for. Neither a percentile rank nor a high scaled score guarantees admission.
Remember, schools may weigh GPA, shadowing, research, extracurriculars, and personal statements alongside your DAT. Your DAT score is one part of the application; review the full requirements of each target school.
Should You Retake the DAT?
Retaking depends on your goals and current score. Consider retesting if:
- Your score does not meet a published requirement for a target school.
- A section score falls below a target school's stated requirement or indicates a weakness you can address.
- You know you underperformed and could improve with targeted studying.
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.
Once you decide to retake or move forward, build your plan with our DAT Study Guide (2026) and review the DAT Exam Dates to lock in your timeline.
What a Good DAT Score Really Means
A good DAT score is not about perfection or competing with anonymous posts online. It is about preparation, balance, and readiness.
Many students get stuck focusing on one specific number they believe they must reach. That mindset often leads to anxiety and burnout — and it misses how dental schools actually evaluate applicants.
Admissions committees may consider more than your DAT score alone. Depending on the school, they may consider how it compares to other applicants in the same cycle and how it fits with your overall academic record — your GPA, science GPA, coursework, letters of recommendation, and personal statement.
A student with a slightly lower DAT score but strong fundamentals and steady improvement may be a stronger applicant than someone with a higher score and weaker preparation.
Improvement matters. Meaningful gains can be part of your application story, but no universal rule guarantees that retakes will be viewed favorably. The ADA reports a history of all testing attempts, and each school decides how to evaluate that record.
Comparing yourself to isolated screenshots online can also be misleading. Those posts rarely show the full picture and often highlight extreme results rather than typical outcomes. A good DAT score is one that places you competitively for the schools you are applying to — not one that matches a number you saw on Reddit.
Frequently Asked Questions About DAT Score Percentiles
What is the highest DAT score?
The highest possible DAT score is 600.
Is a 600 DAT score possible?
Yes. A score of 600 is the maximum score reported on the current DAT scoring scale.
What percentile is the maximum reported DAT score?
AA 600 has a published AA percentile rank of 100. That published rank and maximum scaled score do not prove that every question was answered correctly.
Is the highest DAT score necessary for dental school admission?
The ADA does not establish a universal admissions cutoff or require a score of 600. Each school determines acceptable scores; check your target schools' current requirements.
What does a 21 DAT percentile mean?
A rank of 21 means about 21% of attempts in the reference sample received that score or lower, with approximately 79% higher. It is not the same as an old AA 21. Whether you should retake depends on school requirements and preparation.
What percentile is competitive for dental school?
There is no universal competitive percentile in the ADA testing guidance. Compare your scaled scores and published percentile ranks with each target school's current requirements and dated class profiles.
Does the new 200-600 DAT scoring system change percentiles?
A percentile rank still describes relative standing, but use the ADA table for the correct reporting scale and score type. Do not assume an old-score percentile automatically equals a new-scale percentile.
Is my Academic Average (AA) or Total Science (TS) more important?
AA and TS summarize different combinations of scaled scores. The ADA explains their calculation but does not establish a universal weighting or interview probability. Check how your target schools evaluate them.
What is a good DAT percentile?
For context, AA 430 has a published AA percentile rank of 75. That describes relative standing in the reference sample, not a universal admissions standard.
Is percentile more important than the DAT score itself?
The DAT reports scaled scores, not raw totals. Published percentile ranks provide additional context for those scaled scores. Each school determines how it evaluates examination results.
Why might two sources give different percentiles for the same DAT score?
They may use different score types, reporting scales, or reference samples. Check the table's date and the correct column. The published ADA table cited here does not establish annual recalculation for every candidate.
Do dental schools care more about Academic Average percentile or Total Science percentile?
That is school-specific. AA, TS, Biology, and General Chemistry have separate score and percentile columns. Consult each school's published requirements rather than assume a universal weighting.
Can a small score increase correspond to a different percentile rank?
Yes. In the published AA table, AA 400 has rank 54 and AA 410 has rank 62, an 8-percentile-point difference for a 10-point scaled-score difference. This is a table comparison, not a prediction or guarantee of a future result.
