DAT Score Conversion (2026): How DAT Scores Are Calculated on the 200–600 Scale | DAT Destroyer | OAT Destroyer | Dr. Jim Romano

By Dr. Jim Romano and Nancy Steen — Creators of the Destroyers

Many students ask how DAT score conversion works, especially now that the Dental Admission Test uses the updated three-digit 200–600 scoring scale.

DAT score conversion can refer to two different processes: comparing an older 1–30 score with its approximate equivalent on the current scale, or converting performance on scored exam questions into a scaled score. The ADA’s concordance table addresses old-to-new comparisons; it is not a raw-to-scaled score calculator.

This guide explains old-to-new DAT score comparisons, how scaled and composite scores are reported, and how percentile ranks help you interpret your results. The ADA states that most candidates complete two or more years of college before taking the DAT and encourages candidates to take the examination well in advance of the dental school admission cycle. Allow time for score reporting and, if needed, a retake. If you're also building your study plan, see our DAT Study Guide (2026) and DAT Test Dates (2026) for a complete preparation timeline.

Key facts about the current DAT scoring system

• DAT scores are reported on a 200–600 scaled score
• An Academic Average of 400 corresponds to the 54th percentile in the ADA’s published reference table.
• Scores are equated, not curved
• There is no penalty for guessing

The Step-by-Step DAT Scoring Process

Raw-to-scaled scoring is separate from old-to-new score conversion. The ADA uses psychometric equating procedures to report performance on scored questions on the 200–600 scale. Some exam questions are experimental and do not contribute to your score.

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.

DAT Conversion Chart: Old-to-New Academic Average Scores

The ADA’s concordance table provides approximate equivalents between the older 1–30 DAT scale and the current 200–600 scale. This table applies only to Academic Average (AA). Individual sections and Survey of Natural Sciences have separate conversion columns in the official ADA table.

Source: ADA, Understanding the New DAT Score Reporting Scale, Table 1, page 4. These are approximate old-to-new score equivalents, not a calculator for converting correct answers into scaled scores. Consult the full ADA table for section-specific conversions.

How DAT Score Conversion Works

The ADA does not release the number of correct answers required to earn a particular scaled score. That number varies by examination form. Scale scores are reported from 200 to 600 in 10-point increments.

The DAT reports section scores and composite scores. Academic Average uses five section scale scores; under the current method, Total Science uses the three science section scale 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 performance across Biology, General Chemistry, and Organic Chemistry
• Percentile ranks show how your performance compares to other test-takers

How DAT Score Conversion Works (200–600 Scale Explained)

The ADA does not release a fixed number of correct answers needed to earn each scaled score. Its psychometric procedures account for differences in difficulty between examination forms.

Step 1 — Raw score

Your raw score reflects correct answers to scored questions. Some questions are experimental and are not scored. There is no penalty for guessing.

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 — Understanding Your Percentile Rank

You can look up your scaled score in the ADA’s percentile table to see how it compares with the national reference sample. Percentile ranks differ by score type.

DAT Percentiles – How to Interpret Your Score

How Academic Average (AA) Is Calculated

Academic Average (AA) is the rounded average of five scale scores: Biology, General Chemistry, Organic Chemistry, Reading Comprehension, and Quantitative Reasoning.

PAT is not included.

Example: Add the five scale scores and divide by five to obtain the average. The reported AA is rounded.

How Total Science (TS) Is Calculated

Under the current DAT scoring system introduced March 1, 2025, Total Science (TS) is the rounded average of the Biology, General Chemistry, and Organic Chemistry scale scores. Before that change, Total Science was based on performance across the Survey of Natural Sciences rather than the average of those three scale scores.

What Is a "Good" DAT Score on the New Scale?

There is no official passing DAT score. Each dental education program determines what constitutes an acceptable score. Percentiles describe performance relative to the ADA’s reference sample; they do not establish admission requirements.

Academic Average Percentile Reference

Selected Academic Average values from ADA Table 2, page 5. These published percentile ranks are based on more than 30,000 DAT attempts over a recent two-year reference period. They are not interchangeable with section-specific percentile ranks and are not admissions cutoffs.

DAT Retesting Rules (2026)

If your score is not where you want it, retaking the DAT is an option — but the ADA has specific rules you need to know before planning a retake.

Current DAT retesting policy:

• You must wait 60 days between DAT attempts

• You may take the DAT a maximum of 4 times within any 12-month period

• If you have 3 or more attempts, you must apply to the ADA for permission to retest and provide proof of a recent dental school application

• After your 5th DAT attempt, retesting is limited to once per 12-month period

Plan your retake timeline carefully and allow time to strengthen the areas identified during your preparation.

Ready to Improve Your DAT Score?

Understanding how the DAT is scored is only part of the process. The next step is preparing with study materials that thoroughly cover the topics tested on the exam.

Written by Dr. Jim Romano, DAT Destroyer contains thousands of practice questions with detailed explanations in Biology, General Chemistry, Organic Chemistry, and Quantitative Reasoning.It has helped students prepare for the DAT for many years and is widely recognized by pre-dental students as a valuable study resource.

Frequently Asked Questions

Is the DAT curved?

No. DAT scores are equated, not curved.

Do dental schools see my raw scores?

DAT results are reported as scale scores, not raw scores. The ADA publishes percentile information to help interpret those scores.

Can a strong DAT score offset a lower GPA?

A strong DAT score does not guarantee an interview. Each dental program determines how it evaluates DAT scores and the other parts of an application.

How is the DAT score calculated step by step?

The ADA uses psychometric equating procedures to produce section scale scores. Academic Average is the rounded average of Biology, General Chemistry, Organic Chemistry, Reading Comprehension, and Quantitative Reasoning. Under the current method, Total Science is the rounded average of the three science scale scores.

What is a good DAT score in 2026?

There is no single DAT score that is competitive at every dental school. Each program determines what constitutes an acceptable score. Use the ADA’s percentile table to interpret your performance, then review current admissions information from the schools you are considering.

What is a 400 DAT score?

An Academic Average of 400 corresponds to the 54th percentile in the ADA’s published reference table. Percentiles differ by score type, and this rank does not establish whether the score meets a particular school’s admissions expectations.

What is a 460 DAT score?

An Academic Average of 460 corresponds to the 88th percentile in the ADA’s published reference table. This rank describes performance relative to the reference sample, not an admissions cutoff. Admissions decisions also consider other application factors.
