This chart maps PSA levels to comparable certifications from major agencies with each agency's minimum performance requirements for certification. It may not include every freediving organization worldwide; cross-recognition is assessed individually. Requirements shown are agency minimums and may change — always confirm with the agency's current standards.
PSA requirements per the official divepsa.com curriculum. CMAS figures per CMAS Apnoea Commission international standards (v2021/01); national federations (e.g. KUA Korea) may apply different criteria.
