Certified Kubernetes Administrator (CKA) pass rate & how retakes work
There is no official published pass rate for the Certified Kubernetes Administrator (CKA) exam — like most licensing exams, results are reported as pass or fail, so any specific "Certified Kubernetes Administrator (CKA) pass rate" figure online is an unofficial estimate, not a number from the exam authority. What is defined is the passing score: you must score 66%. If you don't pass, you can retake the exam.
Is there a published Certified Kubernetes Administrator (CKA) pass rate?
No. The exam authority reports each candidate's result only as pass or fail and does not release an official first-time or overall pass rate. Any exact "Certified Kubernetes Administrator (CKA)pass rate" figure you see online is an unofficial estimate, not a number from the authority.
The one "pass" number that is actually defined is the passing score — 66%. That is a passing SCORE, not a pass RATE, and the two are easy to confuse.
