A lot of the most recent discussion is totally devoid of connection to actual facts. Here are a few to chew on for people making furthere posts. Much of this information on the beginning of Scuba comes from this history of NAUI.
- Scuba instruction in the U.S. started at the Scripps Institute in California in California in the early 1950s. Nearby Los Angeles County wanted to start an instructional program, and it sent Al Tillman to Scripps to learn how to do. He became the first Los Angeles County director and later founded NAUI when he wanted to take the model beyond that taxpayer-supported system.
- NAUI struggled to survive, earning little money from instruction. It relied on donations, and it existed for several years on a loan from Bill High.
- Needing to consolidate to save money, it decided in 1965 to focus on California, and it canceled an instructor training course scheduled for Chicago. The Chicago branch quit and formed a new agency--PADI. Seeing that the NAUI model was not working, PADI decided to seek new students where they could be found--in the retail stores.
- Soon after that, a trade organization called the National Association of Skin Diving Stores (NASDS) decided that was the best model as well, and they decided to teach scuba through the shops as well, changing their name by switching "Stores" to "Schools." (They are now SSI.) That was the beginning of the connection between retail and instruction.
- According to Tillman's reflections decades later, the average student coming out of OW training in the modern era is a better diver than the average instructor was back in the good old days.
- Back in the early days when things were done so beautifully, the dropout rate for scuba diving was enormous. People got certified and then quit diving. In an attempt to improve diver retention, Los Angeles County created a new certification--Advanced Open Water, the purpose of which was to introduce divers to different aspects of diving in order to improve interest. NAUI followed suit soon after that, and other agencies followed later.
- According to a thread started a couple of years ago in the Instructor to Instructor forum on ScubaBoard, the turnover rate for GUE instructors is HUGE. (That thread included actual numbers.)
