Every DAT test day story that ends badly starts the same way: the content was fine, but something else went wrong. An ID with a missing middle name. A late arrival because parking was harder than expected. A 30-minute break that turned into 24 minutes of break and six minutes of re-screening, with a section already counting down on screen. None of this is about biology or perceptual ability, and all of it is preventable.
This guide walks through the day in order, using the rules in the ADA's current DAT Candidate Guide and Prometric's published test center policies. Procedures can change and individual test centers differ in small ways, so read the Candidate Guide yourself in the week before your appointment.
Key takeaways
- Bring two original, unexpired physical IDs: one government-issued with photo, name, and signature, and one with name and signature. The name must match your DENTPIN record exactly.
- Arrive at least 30 minutes early. If you show up more than 30 minutes after your start time and are turned away, you forfeit the full fee.
- The day runs up to 5 hours 15 minutes: optional tutorial, Natural Sciences, Perceptual Ability, optional 30-minute break, Reading Comprehension, Quantitative Reasoning, optional survey.
- The break ends automatically after 30 minutes, and you must go back through security to return. Head back early.
- You will not get a score at the test center. Official scores go to your schools and your DENTPIN account in three to four weeks.
The DAT at a glance
| Segment | Items | Time |
|---|---|---|
| Tutorial (optional) | None | 15 minutes |
| Survey of the Natural Sciences | 100 (40 biology, 30 general chemistry, 30 organic chemistry) | 90 minutes |
| Perceptual Ability | 90 | 60 minutes |
| Scheduled break (optional) | None | 30 minutes |
| Reading Comprehension | 50 (three passages) | 60 minutes |
| Quantitative Reasoning | 40 | 45 minutes |
| Post-test survey (optional) | None | 15 minutes |
| Total | 280 items | 5 hours 15 minutes |
The DAT is given year-round by Prometric at test centers in the United States, its territories, and select Canadian locations. The examination fee is $580, and after the ADA processes your application you have a six-month eligibility window to test. Scores are reported on the 200 to 600 scale the ADA introduced on March 1, 2025. For what those scores mean, see What Is a Good DAT Score?
The week before: settle the logistics
Your content review should be tapering by now (our study schedule treats the final week as light review only). Use some of the freed-up time to remove every logistical risk.
Check your ID against your DENTPIN record, letter by letter
The Candidate Guide says the information in your DENTPIN record and application must match your IDs exactly or you will be denied admission. Hyphenated surnames, a second last name, a middle name on one document and not the other, a recent name change: any of these can cause trouble. If something does not match, contact the ADA's testing program well before test day. Do not assume the front desk will make an exception, because the policy leaves them no room to.
| ID rule | What it means in practice |
|---|---|
| Two original, current IDs | One primary and one secondary. Photocopies and phone images are not accepted; only physical IDs count. |
| Primary ID | Government-issued with your photo, name, and signature (a driver's license or passport, for example). |
| Secondary ID | Shows your name and signature (Prometric gives examples such as a debit or credit card). |
| No expired IDs | Check expiration dates now. A license that expires the week of your test is a real risk if your appointment moves. |
| English only | All IDs except passports must be in English. |
Take the tutorial at home and do a route check
The ADA links to a DAT tutorial on Prometric's site that shows the testing interface. Go through it before test day so the optional 15-minute tutorial on the day is a quick refresher, not your first look at the screen. Also drive or ride to the test center once at the same time of day as your appointment. Note where to park, which entrance to use, and how long it really takes.
Take an official practice test if you can. The ADA and Prometric offer DAT practice tests through Prometric's practice test portal, and the ADA's partial fee waiver includes one free practice test for eligible first-time examinees. Seeing the real interface removes one more unknown. Pair it with our guide to taking a full-length practice test the right way.
What to bring, and what to leave at home
Almost everything you bring goes into a locker. The shorter your list, the faster your check-in.
| Bring | Leave in the locker or at home |
|---|---|
| Your two IDs | Phone, smartwatch, and any watch (digital or analog) |
| A snack and water for the break (kept in the locker) | Books, notes, scratch paper, pens and pencils |
| A light layer you can wear in (test rooms vary in temperature) | Jackets and outerwear, hats (religious attire is permitted) |
| Any testing accommodation approvals you received | Jewelry other than wedding and engagement rings |
| Your locker key, once assigned | Good luck charms and similar objects, wallets, keys, lip balm, gum |
Personal earplugs are not allowed unless approved in advance. If you want them, arrange that ahead of time rather than asking at the desk. Medical devices in the testing room require approval through the ADA's testing accommodations process, and the Candidate Guide advises getting accommodations approved before you schedule.
What the test center provides
- Two noteboards (without graph lines) and two low-odor fine-tip markers. Ask for a replacement if a marker is weak before you start.
- An on-screen timer.
- An on-screen periodic table for general chemistry.
- An on-screen calculator in the Quantitative Reasoning section only. There is no calculator for the sciences, which is why our general chemistry guide teaches no-calculator shortcuts.
Check-in, step by step
The Candidate Guide asks you to report at least 30 minutes before your appointment. In our view that is a minimum, not a target. Check-in at a shared test center can be slow if several people arrive at once for different exams.
- Sign in and present your IDs. Staff compare them with your registration. This is where a name mismatch ends your day.
- Store your belongings. Everything except your IDs goes into an assigned locker. Empty your pockets before you are called.
- Biometric capture. The Candidate Guide says your identity is captured biometrically, for example by photograph, fingerprint, or palm vein scan.
- Security screening. Under Prometric's policies you may be asked to turn your pockets inside out, raise pant legs above your ankles, and raise sleeves above your wrists. Staff visually inspect eyeglasses and hair accessories and may use a handheld metal detector wand.
- Escort to your workstation. You receive your noteboards and markers and sit at an assigned computer. Sessions are monitored with video and audio recording.
- Start the tutorial or skip it. The 15-minute tutorial is optional. If you did it at home, you can use a few minutes to settle in and then begin.
Late means late. If you arrive more than 30 minutes after your scheduled start and are refused admission, the Candidate Guide says you forfeit the full testing fee. Build in time for traffic, parking, and a slow line at the front desk.
The test-day timeline
Here is what a full day looks like if you use every optional segment. Hypothetical example: an 8:00 a.m. appointment, with arrival at 7:30.
| Clock time (hypothetical) | Segment |
|---|---|
| 7:30 to 8:00 | Check-in, lockers, biometrics, screening |
| 8:00 to 8:15 | Tutorial (optional) |
| 8:15 to 9:45 | Survey of the Natural Sciences (100 items, 90 minutes) |
| 9:45 to 10:45 | Perceptual Ability (90 items, 60 minutes) |
| 10:45 to 11:15 | Scheduled break (optional, 30 minutes) |
| 11:15 to 12:15 | Reading Comprehension (50 items, 60 minutes) |
| 12:15 to 1:00 | Quantitative Reasoning (40 items, 45 minutes) |
| 1:00 to 1:15 | Post-test survey (optional) |
Two things jump out. The first three hours of testing run without a scheduled break: tutorial, the sciences, and perceptual ability are back to back. And the two sections after the break are the ones most sensitive to fatigue, because reading and math both reward sustained concentration. Eat a real breakfast, and practice full-length tests at the same time of day as your appointment so your energy curve matches.
Section-by-section pacing notes
- Natural Sciences: about 54 seconds per item on average. Move quickly through biology you know to bank time for chemistry calculations. See biology high-yield topics and organic chemistry reactions.
- Perceptual Ability: 90 items in 60 minutes, or 40 seconds each. It comes right after 90 minutes of science, so your focus is already taxed. See why students underestimate the PAT.
- Reading Comprehension: three passages in 60 minutes, so roughly 20 minutes per passage including questions. See our reading comprehension timing strategy.
- Quantitative Reasoning: 40 items in 45 minutes, a little over a minute each, with the on-screen calculator available. See the QR formulas students forget.
There is no penalty for guessing. Before time runs out in any section, make sure every question has an answer.
Using the 30-minute break well
The scheduled break comes after Perceptual Ability. According to the Candidate Guide, the session resumes automatically once 30 minutes have passed, whether or not you are back in your seat. Prometric's policies say that returning from any break means repeating the security procedures, which can include showing ID, signing in, and a biometric check.
A plan that works for many people:
- Minutes 0 to 5: bathroom first, before a line forms.
- Minutes 5 to 18: eat the snack and drink water from your locker. Choose something you have eaten before on practice days.
- Minutes 18 to 22: stand, stretch, breathe. Do not open notes or your phone; the rules prohibit it, and it would not help anyway.
- Minutes 22 to 30: return to the check-in area and go back through screening with time to spare.
Do not use the break to replay perceptual ability questions in your head. That section is scored and finished. Reading Comprehension is next and deserves a clear head.
Unscheduled breaks and problems during the test
You can take an unscheduled break during a section, but the section timer keeps running. The Candidate Guide says that during an unscheduled break you may not access your locker, use a phone, eat or drink from your locker, study, or leave the test center. Use one only if you truly need it.
If something goes wrong (a computer freezes, a noisy neighbor, a marker that dies), raise your hand and tell the test administrator immediately, while you are still at your workstation. Prometric's DAT checklist says that problems not resolved at the center should be submitted in writing within five business days. A problem you do not report at the time is very hard to address later.
When you finish: no score at the center
Candidates who took the DAT before 2025 remember seeing an unofficial score on screen at the end. That no longer happens. When the ADA moved to the 200 to 600 scale, it ended unofficial score reports at the testing site, because the new scoring requires additional analysis after the session. You will finish Quantitative Reasoning, see the optional post-test survey, and then leave with no number.
That wait is uncomfortable, but it has one upside: you cannot make a snap retake decision in the parking lot. Also note that the Candidate Guide says scores cannot be voided or canceled once you have started any part of the exam.
After test day: scores, reports, and next steps
| What | Current ADA policy |
|---|---|
| Official scores | Reported electronically to the schools you selected within three to four weeks, and posted to your DENTPIN account |
| ADEA AADSAS | Receives your scores if you designated any dental school on your DAT application |
| Additional score reports | $55 each, requested through your DENTPIN account |
| Multiple attempts | Schools receive a history of all testing attempts |
| Score audit | Request within 30 days of the reporting date; $105; takes about four to six weeks |
| Retake | Wait at least 60 days between attempts; four attempts maximum in any 12 months |
If your score comes back below your target, do not rebook immediately. Look at which sections dragged the Academic Average down and whether a fix is realistic in the time before your application goes out. Our retake decision guide covers that call, and our AADSAS timeline shows how a retake shifts the rest of your cycle.
If you need to reschedule or cancel
Appointments must be canceled or rescheduled by the business day before the test and at least 24 hours in advance. The Candidate Guide's rescheduling fees depend on how much notice you give:
| Notice before your appointment | Rescheduling fee |
|---|---|
| 30 or more business days | $50 |
| 5 to 29 business days | $70 |
| 1 to 4 business days | $150 |
| No-show | Full testing fee forfeited |
If you are sick or your practice scores collapse in the final weeks, moving the date early is cheap compared with sitting for a test you are not ready for. Just remember your six-month eligibility window, and that a $150 extension of 45 days is available if you need more time.
Night before and morning of
- Both IDs are in my bag, unexpired, and match my DENTPIN name exactly.
- I know my appointment time, test center address, parking, and entrance.
- I am leaving early enough to arrive at least 30 minutes ahead, plus a traffic buffer.
- My break snack and water are packed.
- I am wearing layers without a jacket or hat I need to keep on, and no watch.
- My phone will be off and in the locker.
- I have a plan for the 30-minute break and will return early.
- I will report any testing problem to the administrator immediately.
- No new content tonight. Sleep is worth more than one more flashcard deck.
The short version
Test day rewards boring preparation. Match your ID, arrive early, pack light, know the timeline, and treat the break as part of the test. Then the only thing left to think about is the questions, which is where your months of work should go.
