Registration Information
You must log in, join NDA, or create an account before you begin an application. If you apply using another person's account, you will not be registered to take the test.
Consider renewing your NDA membership or joining before applying for the exam to receive the NDA member rate. If you do not renew or join before submitting your application, you will not be eligible for the NDA member rate. Members save $160 per CDS application and $150 per CDT application.

Scheduling Your Exam Appointment
After an exam application is accepted, a notice from Meazure Learning - Testing Support, testingsupport@meazurelearning.com, will be sent via email about three weeks before the exam window opening. The notice will include the scheduling web link, your username, and your password. When you access the online scheduling system with your username and password, you will be able to choose an exam site, date, and time from the list of available sites.
Please note that appointment times and site locations are on a first-come, first-served basis, and availability may vary with each exam window.
The CDS and CDT exams are administered through Meazure Learning and can be taken in one of two ways:
- Live Remote Proctoring: Take your exam from home or another private location using your own computer and webcam. A live proctor will monitor the session to ensure the exam is taken securely and fairly. Learn more about Live Remote Proctoring.
- Testing Centers (Launching in July 2025): Prefer an in-person setting? You can schedule your exam at a Meazure Learning testing center near you.
