DCBC is a founding member of the International Diving Regulators and Certifiers Forum (IDRCF). Other members of the IDRCF are Australia (ADAS), France, Norway, South Africa, the United Kingdom (HSE) and the International Marine Contractors Association (IMCA). DCBC certificates are recognized by all members of the IDRCF.

Commercial divers and supervisors holding DCBC certificates can be found working all over the world, including in the Far East, West Africa, the North Sea, the Gulf of Mexico, Kazakstan, indeed anywhere where commercial divers are needed.

It is because of this world-wide recognition of DCBC certificates that the major diver training establishments in the USA have modified their training programs to achieve DCBC accreditation. As a result commercial divers in the USA are trained to the highest standard in the world and are able to follow their careers wherever they wish.
