DAT score calculator
Enter how many questions you got right in each DAT section. You get an estimated 200-600 score, the range that estimate deserves and the ADA percentile for every section, plus your Academic Average.

An estimate, not an official ADA score. The ADA equates every form, so a real sitting can land a step either side.
How to read the estimate
Each row gives three numbers. The big one is the most likely scaled score for that many correct answers. The range next to it is the score one question lower and one question higher - roughly the gap between a good and a bad day on the same material. The percentile is where that score sits in the ADA's published percentile table.
The Academic Average is the mean of five scores - Biology, General Chemistry, Organic Chemistry, Reading Comprehension and Quantitative Reasoning - rounded to the 10-point step the ADA reports. Perceptual Ability is left out, and schools read it on its own. Total Science scores the whole 100-question Survey of Natural Sciences as one section.
Where the numbers come from
The ADA does not publish a raw-to-scaled table for the 200-600 DAT. So each section here is read from a table, not a formula: the raw-to-scale results students recorded for the old 1-30 DAT on the same section lengths, carried to the new scale with the ADA's official old-to-new concordance. Below about the median the old record has no rows, so that part of each table is extrapolated. Total Science splits the 100 science questions 40/30/30 the way the section does and weights the three subject tables by length.
These are the same tables our practice tests use. The full method, with sources, is on how DAT600 estimates a 200-600 score.
A worked example
Say a student gets 34/40 in Biology, 25/30 in General Chemistry, 24/30 in Organic Chemistry, 44/50 in Reading Comprehension, 35/40 in Quantitative Reasoning and 78/90 in Perceptual Ability.
- The tables give Biology 420, General Chemistry 410, Organic Chemistry 410, Reading Comprehension 450 and Quantitative Reasoning 480.
- Their sum is 2170; divided by five and rounded to a 10-point step, the Academic Average is 430, the 75th percentile.
- The 83 science questions right make a Total Science of 420 (67th percentile).
- Perceptual Ability is 470 (88th percentile), reported on its own.
One more Quantitative Reasoning question would move that section to 500; one fewer, to 460. That spread is the range the calculator shows.
Selected raw to scaled points
Correct answers and the estimate they convert to, for each section, with the ADA percentile. Generated from the scoring code on every build, so they always match the calculator.

Score calculator questions
Percentiles by score for every scale are in the DAT score guide.
How accurate is a DAT score calculator?
No calculator is exact. The ADA does not publish the table that turns correct answers into a 200-600 score, and it equates every test form, so the same raw count can land a step higher or lower on test day. This one reads each section from raw-to-scale results students recorded on the old DAT, carried to the new scale with the ADA's official old-to-new concordance, and shows a range of one question either way next to every estimate.
How many questions can I miss on QR and still get a 500?
On these tables a 500 on Quantitative Reasoning takes about 36 of 40 right, so 4 misses. For comparison, Reading Comprehension reaches 500 at about 47 of 50. Near the top of the scale every question is worth a large step.
Is Perceptual Ability part of the Academic Average?
No. The Academic Average is the mean of Biology, General Chemistry, Organic Chemistry, Reading Comprehension and Quantitative Reasoning. Perceptual Ability and Total Science are reported separately.
What does the percentile mean?
It is the ADA's published percentile for that score: the share of the ADA's national sample that scored at or below it. A 70th percentile means about seven in ten of that sample scored the same or lower.
Why does the low end of the table look flat or steep?
The old-DAT record stops near the median score. Below it each table is extrapolated in a straight line down to guessing level, so low-end estimates are less certain than those near the top.
