Questions Regarding Certification


    • Do you have any courses to study for the exam on your website?
      • Please read the content on the Studying for the exam page. Several highly useful books are recommended there.

    • What is the difference between an application fee and an exam fee? Why do I have to pay them separately?
      • The application fee reimburses DDNA for the time required to review, approve, and notify of your eligibilty to sit for the exam. The exam fee helps to reimburse DDNA for the large initial costs of developing the exam and the ongoing costs of keeping the test items updated, as well as costs associated the testing procedure itself. You pay the application fee first. This is because you have a two-year window in which to schedule the exam. When you are ready to take the exam, then you pay the exam fee.

    • How long does it take to receive the results of the certification exam?
      • Please wait six to eight (6-8) weeks after your test date to allow the testing company time to grade, validate, and post your exam results. By that time, DDNA can access your final test results from the testing company. Exam result letters will be processed and mailed at about 6-8 weeks after your exam.

    • How is the exam administered?
      • The exam is administered via a computer online – both at the conference and at local testing centers.

    • Why am I getting a notice to renew? Didn’t I just renew?
      • Be sure that you are reading the notice carefully. Membership and certification are two different things. When you renew your membership once a year, you are not automatically also renewing your certification. Likewise, when you renew your certification every two years, this does not automatically renew your membership. If you receive a renewal notice, please read it carefully to see whether it is time to renew your membership or it is time to renew your certification. Please remember that your membership and certification renewal dates are always posted in your profile. You can see your profile once you log in with your username and password (above the green bar near the top of the page). After you log in, click on “Click here to Update Your Information”.

    • Where do I take the local/group exam?
      • Group exams are held once annually at the DDNA Annual Education Conference. The conference location varies year by year. Local exams are listed conveniently on a PDF that you can download from the exam registration page here.

  • Is it required that I maintain my membership in DDNA during the period of time I am certified?
    • Yes, you must maintain your DDNA membership during the entire time you are certified as a CDDN or DDC.  Membership in your professional association is a requirement of certification.  Renewing your certification does not renew your membership.  Membership renewal is separate from certification renewal.  If your membership expires, your certification also lapses, and you may not use the CDDN or DDC credential until you renew your membership in DDNA.
