Certified Kubernetes Administrator (CKA): Requirements & Exam Details

Informational only — not financial or career advice. Exam fees and certification requirements change, and the figures here are accurate only as of the listed verification date. Confirm the current fee and rules directly with the certifying body before you register or budget. We report the official-body exam fee for a single attempt; it excludes prep courses, materials and retakes, and is not the total cost of certifying.

The Certified Kubernetes Administrator (CKA) credential is offered by the Linux Foundation and the Cloud Native Computing Foundation (CNCF). According to published information current as of June 2026, the certification has no formal prerequisites; candidates of any background may register to sit for the exam. The single-attempt exam fee is $445, which includes one free retake attempt should the candidate not pass on the first try. Certification holders must be aware that fees are subject to change, and the issuing body may modify eligibility requirements, pricing, and renewal procedures at any time without notice.

The CKA credential remains valid for two years from the date of award, after which renewal or recertification is required to maintain the credential. Detailed information about renewal procedures, current pricing, and specific eligibility rules should be confirmed directly on the Linux Foundation and CNCF official certification pages before registration, as these requirements and costs may have changed since the verification date noted above.

Register with the issuer. Eligibility, fees and renewal rules are set by Linux Foundation / CNCF and can change — confirm on the official page.
