Renew Certification

Certification Renewal

Because you strive to do your best. Renew your commitment today.

Renewing your ABO certification is about more than simply a renewal process.  It’s about the high standard you hold yourself to and your dedication to excellence.

Renew your board certification today and never stop pursuing your commitment to lifelong learning.


Renewal certification is required every 10 years for all board certified orthodontists, unless you have lifetime certification. 

Certification Renewal Examination (Time-Limited Certifications):

The certification renewal process may be started no earlier than 36 months prior to the expiration date printed on the board certified orthodontist’s certificate.  A new certificate will be awarded stating an expiration date of ten (10) years from the original expiration date, regardless of when the renewal process is completed.   

Successful completion of this exam is required to maintain Board Certification status. Board certified orthodontists completing certification renewal will receive an updated certificate, ABO Educational Toolkit and sample materials. 

Retake Policy: If unsuccessful, an examinee may pursue the BCE up to three times (a different exam assigned for each attempt). If all three opportunities have been exhausted, the examinee will be required to petition the board for further instruction regarding options to fulfill the certification renewal requirements. It is necessary to re-register each time an examinee will be tested. The registration system is set up to accommodate re-registration as early as the same day, and examinees are not charged for re-examination.  

Voluntary Certification Renewal Examination (Lifetime Certifications):

All lifetime board certified orthodontists are encouraged to voluntarily renew their certification. This is a requirement for all lifetime board certified orthodontists before they are eligible to act as an ABO Examiner and/or ABO Director.
