Apply to take the Admission Test for Dental Hygiene (ATDH)

Submit your application 60 to 90 days before you intend to take the exam.

Tips for your ATDH application 

Before you apply, review the official ATDH Candidate Guide (PDF) to learn about exam content, fees, scoring, waivers, and more. As part of the application, you must verify that you agree to the rules and regulations outlined in the Candidate Guide.

Start by obtaining a DENTPIN®. Your DENTPIN is the unique identifier for all your dental testing needs. Request a DENTPIN. If you have previously applied to take a dental exam, please use your existing DENTPIN. Once you have your DENTPIN and password, sign in and apply below.  

Testing fees are non-refundable and non-transferable. There are no exceptions. Your credit or debit card will be charged when you submit your application. Make sure to use a consistent name. When inputting your name, use the name as it appears on your official government issued identification, such as a driver’s license or passport. When you arrive at the test center, the name on the IDs you present must match exactly the name on your application or you will be denied admission to test. If you are denied admission, you will need to submit a new application and you will forfeit your previous fee.

Confirm your eligibility before scheduling your test. Before you can schedule your test, you must receive eligibility confirmation from the Department of Testing Services. This confirmation will arrive via email. Please check your spam folder before contacting the Department of Testing Services for assistance.


If you have applied to test (or taken a test), retrieve your existing DENTPIN.
