The Dental Admission Test is one of the biggest milestones on the way to dental school. Most pre-dental students spend months preparing for it. The hard part is fitting that prep into a schedule already full of classes, work, and volunteer hours.
In this guide, you will learn what the dental admission test covers and where it fits in your pre-dental timeline. You will also learn how to plan your study months so they leave room for experiences that help you understand dentistry. For official rules, the American Dental Association is always the source to check, so we link to it throughout.
The American Dental Association (ADA) runs the DAT. According to the ADA's DAT page, all US dental schools and select schools in Canada accept it. You take it on a computer at a testing center.
The test has four sections:
Two recent changes matter. Since March 1, 2025, the ADA reports scores on a new scale from 200 to 600. The ADA also updated the organic chemistry test specifications, and it encourages students testing from May 2026 onward to review them.
Your DAT score gives schools a common measure of academic readiness. Admissions committees also read your experiences, letters, and personal statement. Those parts show why you chose dentistry and how you work with people. Strong prep for the test and steady real-world experience support each other.
Take the DAT after you finish the courses it covers. The University of Georgia's pre-professional advising office recommends testing once you complete the recommended pre-DAT courses and after two to three months of guided study.
Many students plan their test for the spring or early summer before they apply. That timing lets scores reach schools early in the application cycle. It also leaves room for a retake if you need one. The ADA sets waiting periods and attempt limits, so read the current DAT Candidate Guide before you register.
Here is one common way to plan the year before you apply:
Your plan may look different, and that is fine. The goal is to test when your coursework and study time line up.

Pick a target test date first. Then count back about three months and block study time on your calendar. Plan one or two full-length practice tests along the way. The ADA offers a free online tutorial, so you can see the test format before you start.
Study months can make it tempting to drop everything else. Try to keep one activity at a lighter pace instead. A weekly shadowing shift or a few volunteer hours keep you connected to why you started. Our article on volunteer opportunities for dental students shares ideas that fit busy semesters.
Winter and summer breaks are good windows for longer experiences. Many students schedule them before or after their DAT season, so study and service do not compete. A dental service learning trip is one option. On Smiles Movement trips, students shadow local dental professionals at mobile clinics and help with oral health education for children in partner communities. Read how short-term volunteer trips fit into a busy academic year.
Keep a short note after each shadowing shift or volunteer day. Write what you observed and what you want to learn next. On hard study days, those notes remind you why you chose this path. Later, they become material for your personal statement and interviews.
A strong DAT plan includes time for study and time for growth. If you want to use a school break to learn alongside dental professionals, Smiles Movement can help. Fill out the form on this page to get more information about upcoming programs and trip dates.
The DAT takes just over four hours of testing time across its four sections. Plan for a full morning or afternoon at the testing center, including check-in.
Yes. The ADA allows retakes with a required waiting period and limits on attempts. Check the current DAT Candidate Guide for the exact rules before you schedule.
Some do. The ADA notes that select Canadian schools accept its DAT. Canada also has its own Canadian DAT, so confirm what each school accepts.
