DAT Percentile Calculator
Convert DAT scaled scores (200-600) into official percentile ranks for AA and each section.
| Section | Score Entered | Score Used | Percentile |
|---|---|---|---|
| Academic Average (AA) | 420 | 420 | 69th |
| Survey of Natural Sciences (SNS) | 420 | 420 | 67th |
| Biology (BIO) | 420 | 420 | 67th |
| General Chemistry (GCH) | 420 | 420 | 66th |
| Organic Chemistry (OCH) | 420 | 420 | 67th |
| Perceptual Ability (PAT) | 420 | 420 | 65th |
| Quantitative Reasoning (QRT) | 420 | 420 | 67th |
| Reading Comprehension (RCT) | 420 | 420 | 69th |
Official DAT scaled scores are reported in 10-point increments (200-600). If you enter a non-standard score, this tool rounds to the nearest official increment.
This DAT percentile calculator converts your scaled score into percentile rank using official ADA reporting data.

How we built this calculator
This tool uses official DAT organizer data only:
- We took Table 3: DAT Percentile Rank Table (3-Digit Scores) from ADA's official "Understanding the New DAT Score Reporting Scale" PDF.
- We encoded the exact score-to-percentile rows for all official scale points (200 to 600 in 10-point increments).
- For any non-standard input value, we round to the nearest official score increment before lookup.
No third-party percentile estimates are used in the core lookup logic.

Important note about percentiles
Percentiles describe how your score compares to a national testing cohort. They can shift over time as testing populations change, so check the ADA source tables for updates in future testing cycles.
