Certified Kubernetes Administrator (CKA) Upcoming Program Changes

The CKA exam will be updated in the coming months, but not before January 15, 2025.

The CKA exam will be updated in the coming months. These updates are part of our ongoing efforts to ensure that a Certified Kubernetes Administrator (CKA) has the most updated skills, knowledge, and competence needed in the industry.

While we do not have a final release date, the changes will not be made before January 15, 2025. 

What is changing on CKA? 

  • The CKA domains (i.e. Storage, Troubleshooting, etc.) will remain unchanged but please review the upcoming changes to competencies (some additions/deletions and updated language which are outlined below each domain heading).
  • Any CKA exam taken after the updated release will test on the new set of Domains and Competencies (see below for updates).

NOTE: It does NOT matter if the exam reservation happens to be for a first attempt or a retake, nor does it matter on what date you completed the exam purchase.  The only date that matters is the date you sit for the exam.

  • Demonstrate their ability to do basic installation as well as configuring and managing production-grade Kubernetes clusters.
