Dive leader is the title of an internationally recognised recreational diving certification. The training standard describes the minimum requirements for dive leader training and certification for recreational scuba divers in international standard ISO 24801-3 and the equivalent European Standard EN 14153-3. Various organizations offer training that meets the requirements of the dive leader standard. Some agencies use the title "Dive Leader" for their equivalent certification, but several other titles are also used, "Divemaster" may be the most widespread, but "Dive Supervisor" is also used, and should not be confused with the very different status and responsibilities of a professional diving supervisor. CMAS affiliates certifications which meet the requirements of CMAS 3-star diver should meet the standard by default. The occupation of a dive leader is also known as "dive guide", and is a specialist application of a "tour guide".
Scuba dive leaders are considered competent to plan, organise and conduct dives and to lead other recreational divers on open water dives, and for specialised recreational scuba diving activities for which they have been trained. They are also considered competent to conduct emergency procedures associated with these activities and the relevant diving environment. They may require orientation for unfamiliar local environmental conditions. Additional specialised training and experience is required to lead divers on more demanding dives.
The term is also used by BSAC for a specific certification.
International standard ISO 24801-3 includes:
Prerequisites for training, including age and health requirements:
Minimum age 18 years,
Minimum certification is to comply with all requirements for ISO 24801-2 level 2 Autonomous diver with logged experience in at least 60 logged dives, or 50 dives with at least 25 hours dive time, of which 40 must have been done after qualifying at level 2. Dives should include:
Night diving;
Diving in low visibility;
Deep diving;
Underwater navigation;
Diving in a current of at least 0.

Diver training is the set of processes through which a person learns the necessary and desirable skills to safely dive underwater within the scope of the diver training standard relevant to the specific training programme.
Recreational diver training is the process of developing knowledge and understanding of the basic principles, and the skills and procedures for the use of scuba equipment so that the diver is able to dive for recreational purposes with acceptable risk using the type of equipment and in similar conditions to those experienced during training. Not only is the underwater environment hazardous but the diving equipment itself can be dangerous. There are problems that divers must learn to avoid and manage when they do occur.
Diver rescue, following an accident, is the process of avoiding or limiting further exposure to diving hazards and bringing a diver to a place of safety. A safe place is often a place where the diver cannot drown, such as a boat or dry land, where first aid can be administered and from which professional medical treatment can be sought. In the context of surface supplied diving, the place of safety for a diver with a decompression obligation is often the diving bell.
Natural Language Processing (NLP) has become increasingly utilized to provide adaptivity in educational applications. However, recent research has highlighted a variety of biases in pre-trained language models. While existing studies investigate bias in di ...
