Commercial divers are registered with the Department of Employment and Labour after completing their training and assessment at registered commercial diving schools. The standard of training is officially specified in the Commercial Diver Training Standards for each class of diver, but the precise definitions for many of the specified items is unclear. However this is not unlike the standards for training in several other countries, as the SA standards are similar to the standards published by the International Diving Regulators and Certifiers Forum (IDRCF) of which the SA Department of Employment and Labour is a member.
