DAT score conversion chart, DAT percentile ranks and what counts as a good DAT score

The DAT moved from a 1 to 30 reporting scale to a 200 to 600 scale on March 1, 2025, and the ADA published a concordance table so the two can be compared. On that table an old Academic Average of 18 is about a 390 today, an old 20 is a 420, an old 21 is a 440 and an old 22 is a 460. Read the other way, a 450 sits between the old 21 and 22, and it is the 85th percentile nationally. There is no passing score on the DAT, so the real target is the median of the schools you are applying to, which for most applicants means an Academic Average in the 420 to 450 range.

Here is the catch that trips up a lot of applicants in 2026: the DAT changed scales. Until March 1, 2025 the test used 1 to 30 standard scores, and almost every "you need a 20" rule of thumb was written for that scale. The exam now reports 200 to 600 in 10-point steps, so the advice you find on older forums no longer matches the number on your score report. Let us translate it properly.

What is a good DAT score?

A good DAT score is one that clears the median of the programs you actually want, and for most applicants that means an Academic Average somewhere in the 420 to 450 range. On the new scale, 400 is roughly the national midpoint, so a 420 already puts you comfortably above average at about the 69th percentile. Selective programs draw from a stronger pool, so 450 and up (near the 85th percentile) is the zone where the DAT stops being the thing that holds an application back. None of these are official cutoffs, because dental schools do not publish hard lines and they read the DAT alongside your GPA, shadowing hours and personal statement.

How the new 200 to 600 DAT scale works

The DAT reports several scores, and it helps to know which one people mean when they say "a good score." Your Academic Average (AA) is the rounded average of five subjects: Biology, General Chemistry, Organic Chemistry, Quantitative Reasoning and Reading Comprehension. Total Science (TS) is the average of just the three science subjects. The Perceptual Ability Test (PAT) is reported on its own and is not part of the AA. Each of these is now on the 200 to 600 scale. When an admissions page or an applicant talks about "a 20," they almost always mean the old AA, and on the concordance an old 20 lands at about 420 today, while an old 21 is roughly 440.

How is the DAT scored?

The DAT is scored on a 200 to 600 scale in 10-point increments, where 400 is set at roughly the 50th percentile of test takers. You get a scaled score for each of the five academic subjects, an Academic Average, a Total Science score and a separate Perceptual Ability score. There is no passing score and no penalty for guessing, so answer every item.

One procedural change catches people out. Since the March 1, 2025 scoring switch, you no longer see unofficial scores at the test center when you finish. The three-digit scale requires additional statistical analysis before scores are released, so results now arrive a few weeks after your test date. Plan your application timeline around that delay rather than assuming you will walk out knowing your number.

One change to check before you sit the DAT in 2026

The ADA has flagged that updates to the DAT Organic Chemistry Test Specifications are expected in April 2026, and it advises anyone testing in May 2026 or later to review the new Organic Chemistry Examination Specifications and to keep checking for revisions. Organic chemistry is one of the three subjects inside the Survey of the Natural Sciences and it feeds the Academic Average, so a specification change is worth ten minutes of your time before you buy a question bank. If a course was built against the previous specifications, some of what it drills may no longer be on the test, and something that is may be missing.

DAT score conversion chart: the official old-to-new concordance table

This is the concordance table the ADA's Department of Testing Services published with the scale change, reproduced in full. It converts a DAT score on the old 1 to 30 reporting scale to its approximate equivalent on the new 200 to 600 scale, for every subscore. The ADA built it from more than 30,000 DAT attempts over a recent two-year period, scoring each attempt under both systems and matching scores that occupied the same relative position in their own distributions.

Read it left to right. An old Academic Average of 20 is approximately a 420 today. An old 21 is a 440. The Perceptual Ability column moves fastest at the top end, which is why an old PAT of 25 converts to 550 while an old Academic Average of 25 converts to 510: the PAT distribution is shaped differently from the science sections and the conversion respects that.

Note that since March 1, 2025 all DAT results reported to ADEA AADSAS appear on the 200 to 600 scale, including scores from administrations before that date, which the ADA converted psychometrically. Your original two-digit scores remain visible in the DTS Hub.

What is 450 on the DAT in old scores?

An Academic Average of 450 sits between the old 21, which converts to 440, and the old 22, which converts to 460, so it is roughly an old 21 to 22. That is the most searched conversion and it is worth understanding why it is awkward: the new scale reports in 10-point increments across a 400-point range, so it carries more resolution than the old 30-point scale did. Some new scores land between two old ones, and no exact old equivalent exists. Here are the conversions people ask for most, read backwards out of the ADA table.

Is 460 a good DAT score?

Yes. An Academic Average of 460 is the 88th percentile nationally, which means you scored at or above roughly 88 out of every 100 candidates, and it converts to an old-scale 22. That is a competitive number at most US dental schools and a strong one at many. It is not a guarantee anywhere, because programs read the DAT alongside your science GPA, your experience and your interview, and the most selective schools draw applicants from higher in the distribution. But at 460 the DAT has stopped being the weak part of your application, and time spent pushing it higher is usually worth less than time spent on the rest of the file.

DAT percentile ranks by section, 300 to 600

Percentiles are the honest way to read a DAT score, because they tell you where you stand against everyone else regardless of which scale you tested under. A percentile rank is the percentage of candidates in the national normative sample who scored at or below that number. The ADA built these ranks from the same sample of more than 30,000 attempts.

Every score below 300 falls at or under the 8th percentile on every section, which is why the table starts there. Two things stand out. First, the middle of the scale is steep: on the Academic Average, moving from 390 to 430 takes you from the 47th percentile to the 75th, so 40 points in the middle is worth far more than 40 points at either end. Second, the top compresses hard. Academic Averages of 540 and above are all reported at the 100th percentile, so there is nothing to gain by chasing a perfect score once you are past about 510.

What DAT score do you need for dental school?

There is no single number, because every school sets its own expectations and none of them publish a firm cutoff. What you can do is look up the average accepted DAT for the programs on your list, which many schools and the ADEA report, and aim to be at or above it. As a working rule for 2026: an Academic Average around 420 keeps you in the running at a broad set of programs, the mid-440s makes you competitive at most, and 450 and up strengthens an application to the more selective schools. Remember the DAT is one factor. A strong science GPA and clinical experience can offset a merely average DAT, and a high DAT will not rescue a weak overall file. It also helps to know what the road looks like past admission: the exam that actually licenses you is the INBDE, and working through INBDE practice questions is a problem for your second and third year, not this one.

Do not forget the Perceptual Ability score

Because the PAT sits outside the Academic Average, applicants sometimes underweight it, and that is a mistake. Many programs look at the PAT specifically because spatial reasoning matters in clinical dentistry, and it is the section where dedicated practice moves your score the most. The PAT has six subtests: keyhole, top-front-end views, angle ranking, hole punching, cube counting and pattern folding. None of it rewards memorization. It rewards reps until the mental rotations become automatic, which is exactly why timed, high-volume practice with worked explanations pays off here more than anywhere else on the test. The PAT is also the one section the optometry admission exam drops entirely, so if you are weighing both fields, it is worth understanding how the OAT compares to the DAT before you commit to one test.

How to raise your DAT score

Score gains on the DAT come from volume and review, not from re-reading a prep book. Most applicants study 200 to 400 hours over two to four months, built around full-length practice and thousands of questions with every answer reviewed. The loop that works is simple: do questions, miss some, learn exactly why the right answer was right, and drill the topics you keep missing rather than the ones you already have. When you review the sciences, keep your material current, especially organic chemistry, since the ADA is refreshing the organic specifications in April 2026 without major content changes. If you learn well from watching, you can even turn a recorded biology lecture into a quick quiz and test yourself on it instead of watching passively.

That retrieval-first habit is what an AI tutor is built to feed. It generates unlimited DAT-style questions on the exact section you keep missing, explains each answer choice, and lets you push harder on organic chemistry or the PAT without running out of material. Start with unlimited DAT practice questions on the current 200 to 600 exam, and if you are also weighing dental against medical school, our MCAT practice tests cover that path too.

The short version

A good DAT score in 2026 is an Academic Average around 420 to 450 on the new 200 to 600 scale, with 400 being roughly average and 450-plus strong for selective programs. Ignore old advice quoting 1 to 30 scores unless you translate it through the concordance, target the median of your specific schools, and do not neglect the Perceptual Ability section. Then put your hours into reviewed practice questions, because that is what actually moves the number.
