DAT Score Percentiles: The Official ADA Data, Explained

Every number on this page comes from one source: the ADA's official publication "Understanding the New DAT Score Reporting Scale" (updated 01/29/2025), built from the ADA's national normative sample of 30,000+ DAT attempts over a recent two-year period. We're not estimating, rounding from a forum post, or extrapolating a curve — every figure below is copied directly from the ADA's own concordance and percentile tables, which you can verify yourself at ada.org.

We built this page because the 2025 scale change left a gap: applicants, pre-dental advisors, and even some admissions blogs have been guessing at what a 470 or a 22 AA actually means, and most of what's circulating online is unsourced. This is meant to be the page you cite instead — bookmark it, link it, quote it.

Why the DAT score scale changed in 2025

Starting with the new score reporting scale, the ADA moved DAT section scores from the old 1–30 range to a new 200–600 range, in 10-point increments. The change didn't alter what the exam measures or how it's scored underneath — it changed how that score is displayed, similar to how other standardized admissions tests have re-scaled over time. The ADA published an official concordance table mapping every old score to its new equivalent, plus a percentile table showing where every new score falls in the national distribution. Both tables are reproduced in full below.

Table 1: Official DAT score concordance (old 1–30 → new 200–600)

This is the ADA's direct old-to-new conversion, section by section. AA is Academic Average; SNS is Survey of Natural Sciences; BIO, GCH, and OCH are Biology, General Chemistry, and Organic Chemistry; PAT is Perceptual Ability; QRT is Quantitative Reasoning; RCT is Reading Comprehension.

Table 2: Official DAT score percentile ranks (new 200–600 scale)

Note: percentile rank means the percent of candidates in the ADA's normative sample who scored at or below that score — not the percent who scored higher. A 91st percentile score means 91% of test-takers scored the same or lower, and roughly 9% scored higher.

What an average DAT score looks like now

There's no single official "average" published by the ADA — but Table 2 lets you locate the middle of the national distribution directly. A 390 Academic Average sits at the 47th percentile, and a 400 AA sits at the 54th percentile. So the midpoint of the new scale — where roughly half of test-takers land above and half below — falls in that 390–400 AA band. If your practice scores are sitting there, you're solidly in the middle of the national applicant pool, not below it.

What counts as a competitive DAT score

Pulling directly from Table 2's AA column, here's where the commonly cited "competitive" benchmarks actually land nationally:

• 430 AA — 75th percentile
• 450 AA — 85th percentile
• 470 AA — 91st percentile
• 500 AA — 97th percentile

Every dental school sets its own admissions bar, and none of those thresholds are official cutoffs — but the percentile context matters. A 470 AA isn't just "a good score" in the abstract; per the ADA's own normative data, it means you outperformed roughly 9 out of every 10 people who sat for the exam over that two-year sample period.

Old-scale to new-scale translation, at a glance

If you studied on the old 1–30 scale, or you're comparing your score to an older friend's, forum post, or admissions chart, here's the direct conversion straight from Table 1's Academic Average column:

• 20 AA (old) → 420 (new)
• 21 AA (old) → 440 (new)
• 22 AA (old) → 460 (new)
• 25 AA (old) → 510 (new)

Notice the conversion isn't a flat multiplier — the gap between consecutive old scores widens as you move up the scale (20→21 is a 20-point jump, but 24→25 is a 20-point jump too, while 21→22 is also 20 points but 22→23 is only 10). That's because the new scale was built to preserve each score's percentile position, not to apply a simple arithmetic conversion — which is exactly why the ADA published a lookup table instead of a formula.

Why the same number means different things in different sections

This is the detail most translation charts flatten out, and it's directly visible in Table 2: a given 3-digit score does not sit at the same percentile across every section, because each section has its own score distribution among test-takers.

Take 470. On the AA column, 470 is the 91st percentile. On the PAT column, that same 470 is only the 88th percentile. On OCH, it's also 88th. That three-point percentile gap exists because Perceptual Ability and Organic Chemistry scores are distributed slightly differently across the national sample than the overall Academic Average is — more test-takers cluster at or above 470 on PAT and OCH than on AA. Practically, this means a "470 PAT" and a "470 AA" represent different levels of relative standing, even though the raw number is identical. If you're comparing your section breakdown to your Academic Average, use the matching column in Table 2 rather than assuming they line up.

How we use this data ourselves

We scored in the top 3% on the DAT (97th-plus percentile) and now attend the #1-ranked dental school in the world, and even we had to go find the ADA's original PDF to get these numbers right rather than trust the secondhand charts floating around Reddit and admissions forums. Our advice: whenever you see a DAT percentile or old-to-new conversion claim anywhere — including on our own site — check it against the ADA's source document linked at the top of this page. Scores and percentiles are the one place in DAT prep where "close enough" isn't good enough, because a single misquoted number can shift how you and your advisor read your entire application.
