That ain't true, Dave ... they teach quite a lot. What they don't do is guarantee you a C-card at the end of the class.
I do believe, however, that they'd serve their students better by making it a two-part class, with about six or eight weeks in between part 1 and part 2 to practice the skills they're gonna show you ... the ones that your OW and AOW instructors somehow left out of their curriculum ...

I expect you are right Bob, and I may have overstated my feelings but I do feel that with fundies the onus is on the diver to seek out mentorship and guidance for a successful completion where in most other dive training I have been involved in the instructor provides all the instruction required for certification and does not rely on the divers buddies or whatever to fill in the blanks.
For those divers who don't have the resources of like-minded buddies (mentors) or a local instructor fundies can be a very frustrating experience. I know because I have been able to pick up quite a number of tech students who were disillusioned with their fundies training.
When I teach intro to tech I only teach in doubles and I only teach to those who are planning in enrolling in a tech oriented program. The program where I teach buoyancy control, trim, fin kicks and gas management for non-tech divers is called advanced open water (AOW)
