If you’ve recently taken or are preparing for the Dental Admission Test (DAT), you’ve probably noticed a big change — the traditional 1–30 scoring scale has been replaced with a new three-digit scale (200–600) starting in March 2025.
At first glance, the numbers might look confusing. A score of 440 doesn’t sound like a “20,” but that’s about what it represents on the old scale. This quick reference guide will help you interpret the new system and see how your scores compare.
Why the DAT Changed Its Scale
The American Dental Association (ADA) updated the DAT’s scoring to provide greater precision and a wider performance range.
-
The old 1–30 system didn’t allow for enough distinction between closely ranked students.
-
The new 200–600 format gives admissions committees more detail about where you stand nationally.
Just like before, your raw number of correct answers is converted to a scaled score — and there’s no penalty for guessing.
DAT Score Conversion Chart (Old → New Scale)
| Old Scale (1–30) | Approx. New Scale (200–600) | Percentile Estimate |
|---|---|---|
| 17 | ~400 | ~50th (average) |
| 18 | ~420 | ~60th |
| 19 | ~440 | ~70th |
| 20 | ~460 | ~75th |
| 21 | ~480 | ~85th |
| 22 | ~500 | ~90th |
| 23 | ~520 | ~95th |
| 24–25 | ~540–560 | ~97th + |
| 26–30 | ~580 + | ~99th |
Note: Percentiles shift slightly each year depending on the overall pool of test takers.
Interpreting Your Score
Here’s how most dental schools will read your new-format results:
-
400 – National average (around the 50th percentile)
-
440–460 – Above average; competitive for many programs
-
480–500 – Excellent; top 10–15% of examinees
-
540 + – Exceptional; typically 95th percentile +
Remember, schools evaluate your entire application — GPA, shadowing, research, and personal statement — not just your DAT score.
