Frequently Asked Questions About DAT Dates
When should I register for the DAT?
It’s best to register for the DAT at least two to three months before your preferred test date. Seats can fill quickly, especially in summer when many pre-dental students take the exam after finishing prerequisite courses. Registering early gives you more flexibility to choose a convenient date and location.
How often can I take the DAT?
The American Dental Association (ADA) allows you to take the DAT up to three times without special permission. After that, you’ll need approval to test again. Keep this in mind when selecting your DAT dates — most students aim to be fully prepared before scheduling their first attempt so they don’t waste an attempt.
Can I reschedule my DAT test date?
Yes. You can reschedule your DAT test date through the Prometric website, but fees apply depending on how close you are to the exam.
-
30+ days before: $25 rescheduling fee
-
5–30 days before: $60 rescheduling fee
-
1–4 days before: $125 rescheduling fee
Planning ahead helps you avoid unnecessary costs.
What’s the best time of year to take the DAT?
Most students target late spring or early summer (May–July). This timing allows you to complete prerequisite courses, apply early in the dental school cycle, and still have time to retake the exam if necessary. However, the “best” DAT dates depend on your own schedule and level of preparation.
Are DAT dates available year-round?
Yes, the DAT is offered year-round at Prometric testing centers. You aren’t limited to certain months. That flexibility means you can choose dates that align with your study plan, school schedule, or other commitments.
How do DAT dates impact my dental school application?
Dental schools run on a rolling admissions system, which means earlier applications are often reviewed more favorably. If you take the DAT later in the summer or fall, your application may be considered later in the cycle. Choosing earlier DAT dates (May–June) gives you the advantage of being in the first pool of applicants.
How far in advance should I start studying before my DAT date?
Most students prepare for about 2–4 months before their DAT test date, depending on how strong their science foundation is. Non-traditional students or those who have been away from the sciences may need extra time. The key is to select a DAT date that matches your readiness — not just the calendar.
What if my preferred DAT date is not available?
Seats can fill quickly at popular testing centers. If your first choice DAT date isn’t available, consider:
-
Expanding your search radius to nearby testing centers.
-
Looking at weekday dates instead of weekends.
-
Scheduling a slightly earlier date if you’re already prepared.
💡 Final Tip: When planning your DAT dates, think beyond just test day. Build in enough prep time, apply early in the cycle, and make sure your chosen date aligns with your overall dental school timeline.
