U.S. Scuba Training Agencies

The first category includes all U.S. agencies that certify for recreational scuba diving. The next two categories include agencies that certify for technical diving and cave diving. In each category agencies are listed by alphabetical order. Where available, a link to the organization's web site is provided (underlined and in color). Please note that both physical and internet addresses are subject to change. See Section U for a list of some comprehensive scuba web site addresses; by surfing one or more of these sites you should be able to obtain the latest information about the agencies.

Please note that certification policies for nitrox and cave diving are in a state of flux, and that many traditional recreational diving agencies now offer training in "technical" diving skills, particularly nitrox diving.
