There are other diving organisations which provide training and qualifications / certification for sport diving e.g. Scottish Sub-Aqua Club ( SSAC ), Sub-Aqua Association ( SAA ), PADI, SSI, NAUI amongst others, and most offer certification corresponding to internationally accepted CMAS grades, although there are differences in course content and development skills when compared with similar BSAC grades.

Organisations such as PADI, SSI, and NAUI, which originated in the USA , are essentially commercial operations who issue certification. They generally do not operate local branch or club activities of the type provide by the BSAC Branch structure. Further, the costs of training and certification tend to be higher, due to their commercial orientation.
