ISO 11121:2017 specifies minimum programme content requirements for training organizations for introductory scuba experiences in recreational scuba diving. Under no conditions are these requirements considered to be a standard for the training and qualification of scuba divers.
ISO 11121:2017 applies to programmes that include participants being taken into an open water environment. It does not apply to programmes that are exclusively conducted in a confined water environment (e.g. swimming pools).
ISO 11121:2017 also specifies the conditions under which this service is to be provided, which supplement the general requirements for recreational diving services specified in ISO 24803.
