Diver training is essential for safe diving. Not only is the underwater environment hazardous but equipment such as SCUBA can be dangerous to the untrained. Diving in the sense of going underwater, has these purposes. ... SCUBA is an acronym for Self-Contained Underwater Breathing Apparatus. ...

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. This page lists SCUBA diver training organizations. ...

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
  • amateur instructors. An example of this type is British Sub Aqua Club
• Technical recreational SCUBA diving organisations. Examples of this type are IANTD, DSAT Tec (PADI), GUE 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 training takes place in a local body of water such as a lake, a flooded quarry or the sea. Advanced training mostly takes place at depths and locations similar to the diver's normal diving locations. A body of water is any significant natural pool of water such as an ocean, a lake, or a river, covering the Earth or another planet. ...

Scuba training for younger members

See About training younger children to scuba dive. Some clubs restrict younger children to snorkelling; some do not. Some clubs have a special name for their younger members' group: one word sometimes so used is "Tadpoles" (by extension from the word "frogman").
