Many diver training organizations exist, throughout the world, offering diver training leading to certification: the issuing of a C-card or qualification card. Reputable dive operators, dive shops and compressor operators refuse to allow uncertified people to dive, hire diving equipment or fill diving cylinders.
A good dive training organisation, such as a dive school based at a dive shop, will always offer courses to the standard of a recognised certification organisation, such as those listed below. Many dive shops in popular holiday locations offer courses that can teach you to dive in a few days, and can be combined with your vacation. Upon completing the course the student is issued a certification card.
Sources of diver training
Many diver training organizations exist:
- Entry-level recreational SCUBA diver training organisations using professonal instructors. Examples of this type are PADI and NAUI
- Entry-level recreational SCUBA diver training organisations using amateur instructors. An example of this type is British Sub Aqua Club
- Technical recreational SCUBA diving organisations. Examples of this type are IANTD and NAUI Tec
- Commercial diver training organisations. Train divers for professional diving using SCUBA, surface supplied diving and saturation diving equipment and techniques.
- National navies and armed forces. Train divers for ship maintenance, salvage and repair, rescue, mine clearance and covert operations using SCUBA and more advanced equipment and techniques.
Location of training lessons
Initial training takes place in three environments:
- Classroom - where material is presented and reviewed
- Pool - where skills are taught and practiced in confined water
- Open Water - where the student demonstrates the skills he or she has learned.
Typically, early open water takes place in a local body of water such as a lake, a flooded quarry or the sea.
