DAT exam-day guide
DAT · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the original, unexpired photo ID you registered with. The name on the ID must match your registration name exactly. Confirm with the ADA/Prometric which specific ID forms are accepted and whether a second form of identification is required - policies change, so verify before test day.
Appointment confirmation and DENTPIN
Know your DENTPIN and bring your appointment confirmation (printed or on paper, since phones stay in the locker). Confirm your test center address, appointment time, and reporting time with the provider the week before.
Arrival plan with buffer time
Plan to reach the test center well before your appointment - a 30-minute cushion is a common recommendation. Confirm with the provider how late arrivals are handled, since check-in involves ID verification, a photo, a palm/vein scan, and a locker assignment.
Locker-friendly layers
Test rooms are often cold. Wear comfortable layers and remove anything you would not want to be asked to take off (large jewelry, hats, outerwear with pockets) - the provider may restrict these in the testing room.
Snack and water for the break
Bring a quick snack and a drink to keep in your locker. You may access locker items only during the scheduled break, so pack something easy to eat in a few minutes.
Nothing in your pockets
Phones, smartwatches, notes, and study materials must stay in the locker. Confirm the current prohibited-items list with the provider - an item left in a pocket can end the session.
Skip the last-minute cramming
Do not plan to review notes in the waiting room. Materials are not permitted in the testing area, and last-minute review tends to raise anxiety more than scores.
Scratch materials are provided
You will be given an erasable board or laminated sheets and a marker by the test center; you do not bring your own. Raise your hand if you need a replacement mid-section.
Confirm your score-report designations
Know which dental schools or centralized application service you want scores sent to before you sit down, and confirm with the ADA how designations are selected and whether they can be changed afterward.
Know the section timing cold
Survey of Natural Sciences ~90 minutes (100 items), Perceptual Ability ~60 minutes (90 items), Reading Comprehension ~60 minutes (50 items), Quantitative Reasoning ~45 minutes (40 items). Confirm exact current timings and item counts with the ADA, since the test is periodically revised.
Plan the day
Take your last full-length timed practice test in the morning, at the same hour as your real appointment, so your body clock adapts. After that, stop taking new tests.
Shift to review only: one condensed formula/summary sheet (general chemistry equations, organic reaction patterns, quantitative reasoning formulas) and your PAT strategy notes. No new content, no new question sources.
Verify logistics: reconfirm the appointment time and test center address, check parking or transit, and confirm your ID is unexpired and matches your registration name.
Protect sleep. Go to bed and wake at the times you will use on test day for the remaining three nights.
Light review only, and finish by early evening: skim your summary sheet, reread your pacing plan for each section, then close the books.
Pack now: ID, appointment confirmation, snack, water, layers, and a charged phone for after the test. Lay everything by the door.
Eat a normal dinner, avoid heavy alcohol and an unusual amount of caffeine, and get a full night's sleep. Do not start a new topic tonight.
Eat a real breakfast with protein and fiber, and drink normal amounts of water - not so much that you are uncomfortable during the first 150 minutes, since the first break comes after the Perceptual Ability section.
Leave with your buffer. Arrive early, check in, use the restroom before you are seated, and do not open notes in the waiting area.
Roughly one minute per item. Do two passes: answer everything you know, flag anything that needs calculation or a second look, then return. Never leave a blank - there is no penalty for a wrong answer.
Roughly 40 seconds per item. Keyhole, top/front/end, and hole-punching items reward a disciplined method; skip an item the moment you are stuck and come back.
Eat, drink, and walk. Do not review material and do not sit still staring at a wall. Stay in the permitted area and return before the break timer expires - confirm with the provider whether leaving the building is allowed.
Reading is about 70 seconds per item and quantitative reasoning about 65 seconds per item, so the clock is tighter than it feels. Watch the on-screen timer, and in quantitative reasoning confirm what calculator functions are available to you during the tutorial before the section starts.
Review your unofficial score report on screen, note your standard scores and percentiles, and confirm with the provider when and how official scores reach your designated schools.
Rules to check
Identification is non-negotiable. The name on your ID must match your registration exactly, and the ID must be current and unexpired. If your legal name has changed, contact the ADA well before test day - do not assume a marriage certificate or second document will be accepted at the door. Confirm the accepted documents with the provider.
Only approved items enter the testing room. Everything else - phone, watch, notes, bag, food - goes in the locker, and you may access it only during the scheduled break. Bringing prohibited material into the room can void your session.
The session is monitored and recorded. Any communication with other examinees, attempt to use outside materials or devices, or disruptive behavior is grounds for removal and score cancellation, and it may be reported to the dental schools receiving your scores.
You may move freely within a section but not back into a completed section. Once a section's time expires it is submitted, so answer every item before the clock runs out rather than planning to return to it later. Confirm the exact navigation rules during the pre-test tutorial.
There is no penalty for guessing. Your score is based on correct answers, so budget the last minute of every section to fill in every remaining item.
There is one scheduled break after the Perceptual Ability section; its length and whether you may leave the testing area are set by the provider, so confirm them at check-in. Break time is generally not subtracted from your section time, but the break timer itself runs.
Scores are reported on a 200–600 scale with 300 as the mean. Unofficial scores appear on screen at the end of the session; official reports go to your designated schools afterward, and the turnaround time varies - confirm the current timeline with the ADA.
Retake rules are strict: there is a required waiting period between attempts and a lifetime cap on the number of attempts. Confirm the exact current waiting period and attempt limit with the ADA before you plan a retake, and note that repeated attempts may be visible to schools.
