DAT Retakes: How Many Times, Waiting Period & Cost

Short answer: The ADA caps how many times you can sit for the DAT over your lifetime, and it makes you wait a set period between attempts — both numbers can change, so confirm the current attempt limit and DAT retake waiting period at ada.org before you plan around them. What won't change is this: every retake costs you a real exam fee and real weeks off your application timeline, so the smarter move is almost always figuring out why your first score landed where it did before you register for a second one.

We both landed in the 97th-plus percentile on the DAT, so we're not guessing at the retake math — we're telling you what we'd tell a friend who just walked out of Prometric disappointed. Here's the full logistics picture, then the part most retake guides skip.

How Many Times Can You Take the DAT?

The ADA does not let you take the DAT an unlimited number of times. There's a cap on total lifetime attempts, and going beyond it typically requires special ADA approval rather than a routine registration.

We're intentionally not printing an exact number here — attempt limits are exactly the kind of policy detail the ADA revises, and a specific figure in a blog post is how students end up planning around outdated information. Pull the current lifetime limit straight from the DAT candidate guide at ada.org before you assume you have room to spare.

Two things matter more than the exact number: every attempt counts against your lifetime total, even a strong one you took just to chase a slightly better score, and the cap exists precisely because the ADA wants retakes to reflect genuine improvement, not more tries at the same unchanged approach.

DAT Retake Waiting Period: How Soon Can You Retake the DAT After Failing?

You can't just rebook for the next morning. The ADA enforces a mandatory waiting period before you're eligible to sit for the DAT again, and that window applies whether your last score disappointed you or you simply want a higher one.

Three things to know about how it actually works: the clock starts on your last test date, not your score-release date; the required wait can get longer with each additional retake, so don't assume your second wait matches your first; and Prometric seat availability is a separate problem on top of the minimum wait, since popular centers and dates fill up fast near application deadlines.

The exact number of days is another figure the ADA can adjust, so treat any specific number from a forum thread or older blog post as unverified until you check it against the current DAT candidate guide at ada.org. If your plan depends on retaking in time to submit AADSAS by a certain date, work backward from the official wait period, not a remembered one.

How Much Does It Cost to Retake the DAT?

There's no retake discount — you pay the full exam fee again, in full, every single time you sit for the DAT. The current fee is published on ada.org and changes over time, so we won't quote a number that might be wrong by the time you read this. What we will say: the sticker price is only part of the real cost of a retake.

That last row is the one people underweight. A retake that lands the same score as your first attempt is the worst outcome here — you've paid the fee, spent the weeks, and pushed your timeline back for nothing.

Should You Retake the DAT at All?

Sometimes yes — a score meaningfully below what your target schools typically admit is worth fixing before you apply. But "should I retake" and "how do I retake without wasting another attempt" are different questions, and most guides only answer the first.

Before you register again, ask honestly: Do you know which section actually cost you points (a weak AA can come from Bio, GC, OC, RC, or QR, and PAT is scored separately, so a rough PAT doesn't explain a low AA)? Do you know why you missed what you missed — timing versus content are different fixes? And did your practice scores actually match your real score, or were they never calibrated to real DAT format and difficulty in the first place?

If you're not sure how your section breakdown maps to your overall AA and TS, our guide on DAT test format, sections, and length is a good place to get the structure straight before you diagnose anything.

The Real Fix: Diagnose Before You Retake

Here's the part we think matters most, and it's the reason we built DATPractice. The DAT is a standardized test, which means it rewards a specific, learnable set of content and question patterns — a low score is almost always a symptom of a specific, findable gap, not bad luck. But most students retake blind: they study "harder" in a general direction, sit for the exam again, and hope the extra hours were pointed at the right thing. Sometimes they were. Often they weren't, and the second score barely moves.

The fix is to diagnose before you burn another attempt:

• Run full-length practice tests calibrated to real DAT difficulty and timing. Your practice score only means something if the test mirrors the real thing — otherwise you're diagnosing against a fake target.
• Break every miss down by concept, not just by section. "I lost points in OC" tells you almost nothing. "I lost points on reaction mechanisms specifically" tells you exactly what to study next.
• Re-learn only what the test actually rewards. Going back to a full textbook chapter for one missed concept wastes the exact time you're trying to protect by not retaking blind.

We scored in the top 3% (27 AA with a 29 TS, and 25 AA with a 30 in organic chemistry, legacy scale) not by grinding more hours, but by getting precise about which hours mattered. DATPractice systemizes that into one product: 40 full-length practice tests mirroring real DAT format, timing, and difficulty; an 11,000+ question bank with hand-written solutions for every choice; an AI tutor that finds the concept behind every miss and re-teaches it to test-depth, never more; unlimited custom tests built from your own miss history; and a 60-day plan.

Planning Your Retake Timeline

Once a retake is the right call, treat the logistics as seriously as the studying: confirm your eligibility date against the mandatory waiting period, book your Prometric seat early since good slots near deadlines go fast, and leave real runway before your target AADSAS window.

If you already have an appointment booked and just need to move the date rather than add a whole new attempt, that's a different process — see our guide on how to reschedule your DAT. And if you're weighing whether a released score is even worth acting on before it reaches schools, our piece on canceling your DAT score before release covers that separate decision.
