You don't want to know what our rescue class consists of... It's a university course, but here it is.
16 pool sessions
5 classroom sessions
O2 admin, CPR/AED
Rescue at OWT consists of pulling one of the AI's up from the bottom and towing him 200yards. Said AI is in doubles.
You tow your buddy 500 yards while giving rescue breathing then 500 yards back but you can use a pocket mask and do a chin tow.

Scenario. We drop a dummy in the quarry while everyone is chilling on a SIT and two people have to take fixes, one guy goes out skin diving, while one "calls" 911 and waits at the gate for them, two divers are getting geared up to go find the dummy. They have 4 minutes to get the dummy on the doc on O2 or they fail and get to do it again. It's rather intense, but I have a former Navy combat diver as a boss and he doesn't like to remember that they are just college kids.
so for us the materials is negligible, they do at minimum 10 dives and you have to be in really good shape. Oh, there's a mandatory mask fin snorkel ditch and don as well as a 1200yd circuit. 25yd underwater swim, 375 swim, don MFS while treading water, 25yd underwater kick, 375 kick. you have 15mins to do that, then don scuba gear 200yd dive with mask on back of head and 200 yard just kick around. That is all required for our open water divers too.
With what was said above about NAUI. You can clearly see that we don't follow the "minimum" standards and cover a lot more. With PADI's class in a can mentality, every class is identical. You have to talk to the specific shop about any NAUI class because the requirements are almost always exceeded which is why a shop will choose to teach with NAUI
