How accurate is DAT score conversion?

The conversion is approximate and based on ADA concordance tables. It is intended for comparison across reporting scales, not exact prediction in every admissions context.

What is 420 DAT to old score?

For Academic Average (AA), 420 on the new scale maps to approximately 20 on the old scale.

Can I convert new DAT scores to old DAT scores?

Yes. This tool supports both directions: old 1-30 to new 200-600, and new 200-600 back to approximate old equivalents.

Why can one new score map to a range of old scores?

Some concordance points are grouped, especially at the lower end. In those cases, the tool shows an old-score range instead of a single value.

DAT Score Conversion Tool (Old 1-30 to New 200-600)

If you are comparing older DAT score discussions to current admissions data, you need a reliable way to convert between scales.

This tool handles both:

Old DAT score (1-30) -> New DAT score (200-600)
New DAT score (200-600) -> Approximate old DAT score (1-30)

New DAT score conversion (200-600)

Beginning March 1, 2025, DAT scores are reported on a 200-600 scale.

If you have older references in the 1-30 format, use this tool to convert them to the new reporting system for cleaner comparisons with current admissions benchmarks.

420 DAT to old score (plus 400, 430, 440, 450)

For Academic Average (AA), common lookups are:

400 DAT -> old ~19
420 DAT -> old ~20
430 DAT -> old ~20-21 (nearest concordance logic can vary by section)
440 DAT -> old ~21
450 DAT -> old ~21

Use the score-type selector in the tool because section conversions are not identical to AA.

400 / 430 / 440 / 450 DAT score meaning

These values are frequently searched because applicants want to map older admission advice to current score reports.

For percentile context, see our detailed DAT scoring guide. If you want to estimate scaled scores from raw correct answers, use the DAT score calculator.

When to use this tool

You took the DAT before the scale change and need new-scale context.
You have a new score and want to understand how it compares to old-school references.
You are evaluating trends across older forum posts, advisor notes, or school pages that still mention 1-30 scores.

DAT score conversion limitations

Concordance is designed for approximate comparability, not a perfect one-to-one replacement.
A single converted value can map to a range in reverse conversion.
Section-level relationships differ from AA, so always choose the correct score type.
