ITDA-IHMP, PADI, CMAS and Other Diving Organizations

Divers can complete training through various international certification systems. Among the best-known are PADI, CMAS, SSI, SDI, TDI, IANTD and ITDA-IHMP. Individual organizations use their own names for courses and qualifications, while their levels may in certain cases be approximately compared.

When transferring between organizations or continuing your training, it is therefore advisable to verify the specific qualification directly with an instructor. ITDA-IHMP Agency also allows crossovers for divers, Dive Masters and instructors from other training organizations.

The goal of ITDA-IHMP is to assess a diver primarily according to their actual knowledge, abilities and practical diving skills. The name of a certification alone therefore does not necessarily have to be the only deciding factor when assessing a diver's level.
