What Does AA Mean on the DAT? AA vs. TS Explained

AA stands for Academic Average. It's the average of five section scores — Biology, General Chemistry, Organic Chemistry, Reading Comprehension, and Quantitative Reasoning. It does not include your Perceptual Ability Test (PAT) score, which is reported as its own separate number. TS (Total Science) is a different number entirely: it only averages the three science sections, and it leaves out RC and QR completely.

We've seen this exact mix-up on every practice test debrief we've ever run. A student says "my AA is fine" while staring at their TS, or panics about a rough PAT day thinking it tanked their AA when it mathematically couldn't have. So let's fix the mental model once, with a picture, so you never misread a score report again.

What AA actually stands for and how it's calculated

AA = Academic Average = (Bio + General Chemistry + Organic Chemistry + Reading Comprehension + Quantitative Reasoning) ÷ 5.

That's it. Five sections, one average, equal weight across all five. The DAT reports each of those five sections individually, plus PAT individually, plus TS, plus this one composite — AA — that blends everything except PAT.

Here's the simplest way to see what feeds into AA and what doesn't:

Notice that Bio, GC, and OC each appear in both boxes. That's why AA and TS usually move together and why people conflate them — the three science sections are the shared core of both numbers. The difference is entirely in what gets added on top: AA adds RC and QR, TS adds nothing.

DAT AA score range explained

As of March 2025, the ADA reports DAT scores — including AA — on a 200-600 scale, in 10-point increments, with roughly 400 sitting at the national average. Before that switch, every score used a 1-30 scale, and you'll still see that old scale everywhere: forum threads, older guides, even how a lot of pre-2025 test-takers (including both of us) talk about their own scores.

Rough old-scale benchmarks that are still useful context:

• ~17 AA — around the national average
• 20+ AA — a solid, competitive score at many programs
• 22+ AA — a strong score, comfortably above average
• 25+ AA — roughly top 1-2% of test takers

These are approximate, and the ADA publishes an official concordance table mapping old scores to new ones — that's the source to use if you need an exact conversion rather than a rough feel. Our DAT score conversion chart walks through raw-to-scaled conversions in more detail, and our DAT score percentiles guide breaks down what each AA actually means competitively for admissions in 2026.

TS vs. AA on the DAT: what's the difference

Same three science sections feed both. The difference is scope: TS is a pure science number, AA is a broader academic number that also captures how you read under time pressure (RC) and how you reason with numbers (QR).

Practical takeaway: if your science sections are strong but your RC or QR is weak, your TS will look better than your AA. If it's the reverse — solid RC/QR, shakier science — your AA can actually outperform your TS. Schools that lean on AA as a headline number are implicitly rewarding well-rounded performance across all five, not just science depth.

Does PAT score count toward AA?

No. This is the single most common misunderstanding students bring to us. PAT is scored and reported entirely on its own — it is never blended into AA or TS. You could bomb the PAT and still post a great AA, or ace the PAT and have a mediocre AA. The two numbers are mathematically independent.

That said, don't read "PAT doesn't count toward AA" as "PAT doesn't matter." A lot of dental schools set their own separate PAT minimums or look at it closely alongside AA, precisely because it's the one score that predicts something AA can't: your spatial reasoning under time pressure, which matters a lot in a hands-on clinical field. Check each school's stated expectations through ADEA AADSAS rather than assuming a strong AA covers for a weak PAT.

Why this mix-up costs students real points

Here's the failure mode we see over and over: a student gets a practice score report, sees a TS that looks great, and assumes their AA is just as strong — so they stop grinding science and shift all their remaining time to PAT drills. Then their real AA comes in lower than expected because RC or QR quietly dragged it down the whole time, unmonitored.

The fix is simple but only works if you actually do it: after every full-length practice test, look at all five AA component scores individually, not just the AA number and not just TS. A flat 20/20/20/20/20 (old scale) profile and a 27/27/27/14/12 profile can both produce a similar-looking science score, but they need completely different study plans. Our DAT score calculator lets you plug in raw section scores and see exactly how each one is pulling your AA up or down before test day.

How to use this when you're building a study plan

1. Track all five AA components separately, every practice test — not just the composite.
2. Track TS separately from AA so you know whether your science-specific prep is working, independent of RC/QR noise.
3. Track PAT on its own timeline — it needs dedicated practice regardless of how your AA is trending, since it never blends in.
4. Target your weakest AA component first. Because AA is a simple average, your lowest section has the most room to pull the whole number up.
5. Re-check the trend, not one test. One rough RC section doesn't mean much; three in a row does.

This is exactly the loop we built DATPractice around: 40 full-length tests that mirror real DAT timing and difficulty, an 11,000+ question bank with hand-written solutions for every choice, and unlimited custom tests generated from your personal miss history — so you're always drilling the section that's actually capping your AA, not the one that feels most urgent that week.

The DAT is a standardized test. That means consistent, well-diagnosed practice scores become your real score. Knowing exactly what AA is measuring — and what it isn't — is step one of diagnosing anything correctly.
