Many students ask how DAT score conversion works — especially now that the Dental Admission Test uses the updated three-digit 200–600 scoring scale.
Understanding how DAT scores are calculated, how raw scores are converted, and what those scores mean for dental school admissions is essential for every pre-dental student.
This guide explains exactly how DAT score conversion works, how scaled scores are calculated, and what counts as a competitive DAT score in 2026.
Key facts about the current DAT scoring system
- DAT scores are reported on a 200–600 scaled score
- The national average is approximately 400
- Scores are equated, not curved
- There is no penalty for guessing
What Is DAT Score Conversion?
DAT score conversion refers to how your raw score (the number of correct answers) is transformed into a scaled score between 200 and 600.
Because each version of the DAT varies slightly in difficulty, the American Dental Association uses a process called equating to ensure fairness. This means your final score reflects your performance relative to the exam's difficulty — not just the number of questions you got correct.
How DAT Score Conversion Works
The ADA does not publish a raw-to-scaled score conversion formula. Instead, your DAT score is calculated by converting the number of correct answers in each section into a scaled score between 200 and 600.
Each section is scored independently, and composite scores are then calculated from those section scores.
Important scoring components
- Each DAT section receives its own scaled score
- Academic Average (AA) is the average of: Biology, General Chemistry, Organic Chemistry, Reading Comprehension, and Quantitative Reasoning
- Total Science (TS) reflects combined science performance across Biology, General Chemistry, and Organic Chemistry (TS is not an average of the three scaled scores)
- Percentile ranks show how your performance compares to other test-takers

How DAT Score Conversion Works (200–600 Scale Explained)
While the ADA does not disclose the exact statistical formula, the scoring process follows a well-established framework.
The exact DAT score conversion formula is not publicly released by the ADA, but the equating process ensures that scores are consistent and comparable across different test versions.
Step 1 — Raw score
Your raw score is simply the number of questions answered correctly. There is no penalty for incorrect answers.
Step 2 — Score equating
Your raw score is converted to a scaled score (200–600) using equating, a statistical process that ensures fairness across different versions of the exam.
Step 3 — Percentile assignment
Your scaled score is then associated with a percentile rank, indicating how you performed relative to other DAT examinees.

How Academic Average (AA) Is Calculated
Academic Average (AA) is the simple arithmetic mean of five scaled scores: Biology, General Chemistry, Organic Chemistry, Reading Comprehension, and Quantitative Reasoning.
PAT is not included.
Example: Add the five scaled scores → divide by 5 → the result is your AA.
How Total Science (TS) Is Calculated
Total Science (TS) is based on your combined number of correct answers in Biology, General Chemistry, and Organic Chemistry. That raw total is then converted into one scaled score. TS is not calculated by averaging the three science section scores.
What Is a "Good" DAT Score on the New Scale?
Although dental schools evaluate applicants holistically, these general benchmarks help put scores into context:
- 450+ → Very competitive
- 425–445 → Strong
- 400 → National average
- 360–390 → Below average
- 350 and below → Weak for most programs
DAT Score Range Reference Table (2026)
| Scaled Score (200–600) | Percentile (Approx.) | Competitiveness |
|---|---|---|
| 500–600 | 99th | Exceptional |
| 460–499 | 90th–98th | Very Competitive |
| 425–459 | 75th–89th | Strong |
| 400–424 | 50th–74th | Average / National Mean |
| 360–399 | 25th–49th | Below Average |
| 350 and below | Below 25th | Weak for most programs |

Frequently Asked Questions
Is the DAT curved?
No. DAT scores are equated, not curved.
Do dental schools see my raw scores?
No. Schools only see scaled scores and percentiles.
Can a strong DAT score offset a lower GPA?
Yes. Many applicants with lower GPAs earn interviews due to strong AA and TS scores.
How is the DAT score calculated step by step?
Your raw score (number correct) is converted to a scaled score between 200–600 using equating. Section scores are then averaged to produce your Academic Average (AA). Total Science (TS) is calculated separately from combined raw science answers.
What is a good DAT score in 2026?
On the current 200–600 scale, a score of 400 is the national average. Most competitive dental schools look for 440+ for AA and TS. Top programs like Harvard and NYU typically see accepted students averaging 460–480.
