How we count

These are the credentials members show on their CertDirectory profiles, not every certification in the world: valid or expired ones, from members who have not hidden their credentials. A Kubestronaut holds the official Kubestronaut badge or all five of KCNA, KCSA, CKA, CKAD and CKS; a Golden Kubestronaut holds the official Golden badge or every CNCF certification plus the LFCS. Only totals are shown; countries and teams with fewer than 10 members are merged. Numbers update every night.
