DAT Score Converter: 1–30 to the New 200–600 Scale

In 2025 the ADA replaced the familiar 1–30 DAT scale with a new 200–600 scale, reported in 10-point increments. Overnight, every score you'd ever benchmarked against — the "20 AA" folk wisdom, the "23+ for top programs" threads — stopped mapping cleanly onto score reports. This free converter fixes that. It uses the ADA's own published concordance and percentile tables, nothing else, so what you see here is the same approximate equivalence an admissions office would see.

Two things to know before you convert. First, the ADA is explicit that these are approximate equivalents — the two scales come from different reporting systems, so a conversion is a best available match, not an exact one. Second, the percentile ranks below come from the ADA's national normative sample of more than 30,000 DAT attempts over a recent two-year period, which is exactly the context schools use to interpret the new numbers.

What the 2025 scale change actually means

The scale change did not make the DAT harder or easier — it changed how the same underlying performance is reported. Where the old system compressed everyone into 30 possible scores, the new 200–600 scale spreads candidates across 41 possible values in 10-point steps, which gives schools finer resolution near the middle of the distribution, where most applicants sit. The center of the new scale behaves the way you'd expect: per the ADA's tables, a 400 lands at roughly the 52nd–56th percentile depending on the section.

The other practical consequence: old-scale intuition needs translating, not discarding. The classic "aim for a 21+ AA" advice converts to roughly a 440 — 81st percentile. That's the whole purpose of the concordance table, and why we built this converter instead of letting you eyeball it.

How schools read the new scores

Admissions committees are looking at the same thing they always were: where you stand relative to other candidates. That's why the percentile rank matters more than the raw number on either scale. A 460 in Quantitative Reasoning means 85% of candidates scored at or below you — and that statement stays true regardless of which scale it's printed on. When you're setting a target score, we'd suggest working backwards from a percentile, then using the second tab above to find the new-scale number that gets you there.

One caution from us as former applicants: don't over-read tiny gaps. The ADA calls its own conversions approximate, and a 10-point step on the new scale can move you several percentile points near the middle of the distribution but barely one point at the tails. Trends across your full practice-test history tell you more than any single number.

The official ADA tables behind this tool

Everything above is computed from the two tables in the ADA's document “Understanding the New DAT Score Reporting Scale” (updated January 29, 2025). We reproduce both in full so you can check any conversion by hand. Section abbreviations: AA = Academic Average, SNS = Survey of Natural Sciences, BIO = Biology, GCH = General Chemistry, OCH = Organic Chemistry, PAT = Perceptual Ability, QRT = Quantitative Reasoning, RCT = Reading Comprehension.

Each cell is the percentage of candidates in the ADA's national normative sample (30,000+ attempts over a recent two-year period) who scored at or below that score in that section.
