DAT Scoring Scale Explained: Scores, Range and Percentiles

DAT scores are reported on a 200 to 600 scale in 10-point steps, and every reported number uses that same scale: each section, the Academic Average (AA), and Total Science (TS). Across the 17,430 examinations taken between March 1 and December 31, 2025, the mean Academic Average was 407.84 and the median was 410.

Key takeaways

• The DAT scale runs 200 to 600 in 10-point increments, for every section and every composite.
• The Academic Average is the rounded mean of five sections. The PAT is not one of them.
• Total Science changed definition on March 1, 2025. It is now the rounded mean of biology, general chemistry and organic chemistry.
• Rounding goes to the nearest 10-point step, so a calculated 343 is reported as 340.
• Results arrive three to four weeks after the test date. Nothing is handed to you at the test center.
• A 400 AA is the 54th percentile on the ADA's published table, not the 50th.

How DAT scoring works

1) Raw score vs scaled score

Your raw score is how many questions you answered correctly in a section. Nobody sees it. What gets reported is a scaled score, and the ADA does not publish how many correct answers produce a given scaled score, because that number moves with the difficulty of the form you sat.

2) The 200 to 600 scale

For administrations on and after March 1, 2025, scores are reported on a 200 to 600 scale in 10-point increments, replacing the old 1 to 30 scale. The ADA sets this out in Understanding the New DAT Score Reporting Scale.

Old 2-digit scores are still valid. Since March 1, 2025 every score sent to ADEA AADSAS is reported on the 3-digit scale, including results from earlier administrations, which the ADA converts before sending. Your original 2-digit result stays visible in the DTS Hub. The ADA explains the handover in its DAT scoring and reporting change notice.

3) How a scaled score is produced

Section scores are calculated with Item Response Theory, specifically the three-parameter logistic model. That model weighs three things about every question you answered: its difficulty, how well it separates stronger candidates from weaker ones, and how easy it is to guess.

The practical consequence is the part students get wrong. The DAT does not penalize guessing, so leaving a question blank gains you nothing, but the model does account for how guessable each item is when it estimates your skill. Equating on top of that is what makes two candidates who sat different forms comparable.

4) Academic Average and Total Science

Two of the eight reported numbers are composites, built from the others rather than scored directly.

• Academic Average (AA): the rounded mean of biology, general chemistry, organic chemistry, reading comprehension and quantitative reasoning. The Perceptual Ability Test is excluded.
• Total Science (TS): since March 1, 2025, the rounded mean of biology, general chemistry and organic chemistry.

That second definition is the one most guides still have wrong. For administrations completed before March 1, 2025, Total Science was based on performance across the Survey of the Natural Sciences section and was explicitly not the average of the three science scores. For administrations completed after that date, it is exactly that average. The ADA states both rules on its DAT scores page. So a pre-2025 TS and a post-2025 TS are not the same measurement, even when they are the same number.

5) Rounding

Composites are rounded to the nearest 10-point step. A calculated Academic Average of 343 is reported as 340. This is why your AA sometimes does not match the figure you get by averaging your five sections by hand, and why the DAT score calculator rounds the same way.

6) Unscored items

The DAT includes a small number of experimental questions that are not scored. They look exactly like scored questions, so there is no way to spot one and no reason to try.

DAT score range (200 to 600)

The DAT score range is 200 to 600 for every reported number, in 10-point increments: 200, 210, 220, and so on to 600. There is no passing score. Dental schools set their own expectations.

What is the average DAT score?

For the 17,430 examinations scored on the current scale between March and December 2025, the mean AA was 407.84 and the median was 410, published in the ADA DAT User's Manual. First-time takers averaged 413.9; repeaters averaged 396.3.

The round number you see repeated online, "the average is about 400", is a step below what candidates actually scored. For the mean in all eight reporting areas, and for what admitted students averaged, see our breakdown of the average DAT score.

What is the highest possible DAT score?

The highest DAT score is 600, the equivalent of a perfect 30 on the old 1 to 30 scale. Almost nobody needs it. A 500 AA is already the 97th percentile, and scores in the 480 to 500 range are elite by any school's standard.

DAT sections, questions, and timing

Structure and timing come from the 2026 DAT Candidate Guide:

Total administration time: 5 hours 15 minutes, counting the optional tutorial, break and survey. Report to the test center at least 30 minutes before your appointment. The break after the first two sections is the only scheduled one, and if you take it the session resumes automatically after the full 30 minutes.

If you want section-by-section prep strategy, see DAT sections breakdown, DAT quantitative reasoning guide, and DAT reading comprehension guide.

How each section is scored

Every section is reported on the same 200 to 600 scale, and the three science sections feed two composites at once: each one counts toward your AA and toward your TS.

Balance matters more than it looks. One weak science section moves your AA and your TS in the same direction, so schools see the dip twice.

What is a good DAT score on the new scale?

There is no universal cutoff. What a score is worth depends on your target schools, your GPA, and how even your sections are. To see where a specific number lands, run it through the DAT percentile calculator.

The ADA publishes percentile ranks for the new scale, built on a national normative sample of more than 30,000 attempts over a recent two-year period:

That distinction is worth a minute, because the ADA's normative sample and the 2025 cohort do not give the same answer for the same number. The table above puts a 410 at the 62nd percentile; among 2025 attempts, about 56 percent scored 410 or lower. Our guide to what is a good DAT score works through why the two disagree and which one to quote to a school.

How competitive is your DAT score?

These bands are directional. Always confirm each school's published admitted-student DAT data before you use them to build a list.

For planning, use DAT prep course options, DAT practice tests, and the DAT study schedule.

Old DAT to new DAT conversion

Old scores convert section by section, not with one table for all of them. An old 18 is a 390 Academic Average but a 360 in reading comprehension, so a single conversion chart will mislead you on at least one section.

Our DAT score conversion tool carries the ADA's concordance table with a separate column for the AA and each reporting area, and converts in both directions. Use it rather than a rule of thumb.

When are DAT scores released?

Results are reported electronically within three to four weeks of your test date. They go to the schools you selected on your application and are posted to your DENTPIN account at the same time.

Three details decide what actually happens on test day and after:

• Nothing is printed at the test center. Unofficial score reports stopped on March 1, 2025, because the current scoring system needs analysis that cannot run while you are in the chair.
• Your recipient list is fixed at application. It cannot be edited or cancelled once you submit, and if you selected no schools, no official result is released until you request a report separately.
• An audit is slow. You can ask for your results to be rechecked, but it takes four to six weeks and must be requested within 30 days of the reporting date on your report.

If the result sends you back for another attempt, the retest rules bind before the score does: 60 days between attempts, and a maximum of four administrations in any 12-month period. Candidates with three or more attempts have to apply for permission to test again and show evidence of a recent dental school application.

DAT scoring FAQs

What is a good DAT score?

On the current scale, a 410 AA was the 2025 median, 430 is the 75th percentile and 470 is the 91st. What counts as good depends on your school list and your section balance, but anything above 430 puts you in the top quarter of the ADA's normative sample.

Is 400 a good DAT score?

A 400 AA is the 54th percentile on the ADA's table, a step below the 2025 median of 410. It is workable depending on the rest of your application, but it is not an above-average score.

What percentile is a 490 DAT score?

A 490 AA is the 96th percentile. A 470 is the 91st and a 500 is the 97th, so the gains from each extra 10 points get very small at that end of the scale.

How long does it take to get DAT scores?

Three to four weeks from your test date. Results post to your DENTPIN account and go to the schools you picked at application. You will not be given a score at the test center.

How is Total Science calculated?

For administrations since March 1, 2025, Total Science is the rounded mean of your biology, general chemistry and organic chemistry scores. Before that date it was derived from your Survey of the Natural Sciences performance instead, and the ADA states plainly that it was not the average of the three.

Do dental schools still accept old 1 to 30 DAT scores?

Yes. 2-digit scores remain valid. Since March 1, 2025 they are converted and presented on the 3-digit scale in ADEA AADSAS, so admissions readers compare every candidate on one scale.

Does the DAT include unscored questions?

Yes. A small number are experimental and do not count. They are presented exactly like scored questions.

How should I use my score to decide on a retake?

Compare your section scores, not just the AA, against your target schools' published data. A single weak science section is the most fixable pattern, because it drags your AA and TS together. See how hard is the DAT and the DAT perceptual ability guide before you commit to the 60-day wait.
