mikerault:I doubt the liability for a scuba class would run more than for a football or basketball program...after all for the most part the other participants aren't trying to knock you down and take your equipment...

I agree. I think the primary issues are related to funding and the fact that there is not enough demand for it to make schools go through the major effort it would take to set it up.
You also have to remember that not everyone can teach a high school class. You have to be a certified teacher. That means a school would have to have a scuba instructor who is on the staff, or they would have to have a working relationship with an LDS that would meet all legal requirements of supervision--and tehre are a lot of them.
That being said, I don't think it would be all that hard for a dedicated soul to make it happen. None of this is insurmountable.
