Set any score from your DAT report to see the percentile rank it carries. Every reported score sits on the same 200–600 scale, but each has its own distribution — so the same number means different things on different lines.

Percentile ranks are the ADA’s published figures, from a national normative sample of more than 30,000 DAT attempts over a recent two-year period. An Academic Average of 400 sits at the 54th percentile.
Enter your Academic Average from your score report rather than working it out from the rows above. It is the mean of your five non-PAT scores, but the ADA computes it before rounding — averaging the rounded numbers you were given drifts from the official figure.
What is on a DAT score report
A DAT report carries eight numbers, all on the same 200–600 scale in 10-point steps. Five of them are the sections you sat; the other three are summary scores the ADA derives.
The eight reported DAT scores
Score
What it is
Academic Average (AA)
Mean of the five non-PAT scores. The headline number most schools screen on.
Survey of Natural Sciences (SNS)
Scaled from all 100 science questions together — not an average of the three subject scores below.
Biology
Subject score drawn from the Natural Sciences section.
General Chemistry
Subject score drawn from the Natural Sciences section.
Organic Chemistry
Subject score drawn from the Natural Sciences section.
Perceptual Ability (PAT)
Its own section, reported separately and excluded from the Academic Average.
Quantitative Reasoning
Its own section.
Reading Comprehension
Its own section.
Two things almost every DAT calculator gets wrong
Total Science is not an average. The Survey of Natural Sciences score is scaled from your combined raw performance across all 100 science questions. Averaging Biology, General Chemistry and Organic Chemistry produces a different number, because the three subject scores are themselves scaled separately from overlapping item pools.
The Academic Average cannot be reconstructed from a report. It is the mean of five scores — but of the underlying scores, before each was rounded to a 10-point step. Averaging the five rounded numbers on your report accumulates that rounding. The ADA’s own concordance table shows the two approaches diverging by up to 38 points toward the ends of the scale, which is why this tool treats the Academic Average as something you read off your report rather than something it computes for you.
The same score, different sections
Because each reported score has its own distribution, one number does not carry one meaning. This is worth knowing before you decide which section to put your remaining study time into.

The Academic Average is the mean of your five non-PAT scores: Biology, General Chemistry, Organic Chemistry, Quantitative Reasoning and Reading Comprehension. Perceptual Ability is reported separately and is excluded from it. The ADA computes the average from the underlying scores, not from the rounded numbers printed on your report.
Because every reported score is rounded to a 10-point step before it reaches you. Averaging five already-rounded numbers accumulates that rounding, so the result drifts from the official figure — the ADA’s own concordance table shows the two diverging by as much as 38 points at the extremes of the scale. Your report’s Academic Average is the authoritative number, which is why this tool asks you to enter it rather than deriving it.
No. The Survey of Natural Sciences score is scaled from your combined raw performance across all 100 science questions, not averaged from the three subject scores. It is its own reported score with its own percentile distribution, which is why it appears as a separate line on this calculator.
Every reported DAT score sits between 200 and 600, in 10-point increments. The ADA replaced the older 1-30 scale with this one on March 1, 2025. A score near 400 is around the middle of the national candidate pool.
They are the ADA’s published percentile rank table, calculated from a national normative sample of more than 30,000 DAT attempts over a recent two-year period. A percentile rank is the percentage of candidates in that sample who scored at or below the given score.
No, and this is the most useful thing the calculator shows. Each reported score has its own distribution, so identical numbers sit at different percentiles. Move any two rows to the same score and watch the percentile column disagree.
