From memory (my slates aren't handy - prob a couple things missing, but this is close) - PADI OW checkout dives:
1 - weight check, partial mask flood/clear, reg recovery plus some surface skills
2 - plan dive, full mask flood/clear, hover, alternate air source use, plus some surface skills
3 - mask remove/replace, hover (oral inflation), surface skills
4 - plan & execute an open water dive - basically graduation dive.
All dives - assemble and don gear, predive safety check, entry (positively buoyant), adjust weight as needed, explore dive site, avoid bottom contact, montitor SPG & signal supply remaining and status as instructed, ascend no faster than 60ft per min, safety stop, etc
Open water Dives 1 and 2, -- 12 metres/40 feet
Open Water Dives 3 and 4 – 18 metres/60 feet
> If doing 3 dives in a day, 3rd dive max is 12 metres/40 feet
I generally have my classes do compass work and CESA in conjunction with dive 2.
