What is the DAT?

The Dental Admission Test (DAT) is a test administered by the American Dental Association (ADA). The test is four hours and 30 minutes long and contains four sections. The test is designed to assess your knowledge in: biology, chemistry, organic chemistry, perceptual ability, reading comprehension, and basic math.

How Should I Study?

The DAT is the final challenge before you apply to dental school and should not be taken lightly. Depending on the strength of your scientific knowledge, your study schedule should be between 4 to 10 weeks. Here's a link to my definitive DAT study guide and schedule which will help you prepare.

Register for the DAT.

You should plan on taking the DAT late spring or during the summer of your application year. For example, the class of 2023 should take the DAT in the spring or summer of 2018. You can begin the registration process for the DAT at the ADA's website. Be sure to apply for a test date early as the registration process may take some time.
