Announced in May 2018, the Certified Kubernetes Application Developer (CKAD) program was designed as an extension of CNCF’s Kubernetes training offerings which already includes certification for Kubernetes administrators. By adding this exam to the CNCF certification line-up, application developers and anyone working with Kubernetes can certify their competency in the platform. This certification has been extremely successful with over 5,300 individuals registering for the exam and almost 2,400 achieving certification.

To match other CNCF and Linux Foundation certifications, the CKAD is extending the expiration date of the earned certification from 24 months to 36 months! That means that if you met the Program Certification requirements, your certification will remain valid for 36 months rather than the original 24 months.

To maintain your certification, the requirements have not changed. Certificants must meet the renewal requirements, outlined in the candidate handbook, prior to the expiration date of their current certification in order to maintain active certification. If certification renewal requirements are not completed before the expiration date, certification will be revoked.

If you have already been awarded a CKAD Certification, you should have been contacted. If you have any questions, please reach out to
