Just for a point of clarity, LA County currently uses the term Advanced Diver Program (ADP). I'm not sure if/when they used Advanced Open Water nomenclature.
From my ADP class (and it hasn't changed significantly to my knowledge), the following are true. It was 13 sessions (frequently with morning and afternoon session on the same day but counted as one), plus graduation. We covered Altitude Diving, Night Diving, "wreck" diving, deep diving, navigation, marine ID, basic rescue, skin diving, search and recovery, lift bags, oceanography/dive condition forecasting, dive fitness, multiple different shore type entries, lifeguard services familiarity, alternative gear familiarization (double hoses, full face masks, etc). In water it was 6 pool sessions, 5 beach sessions, 1 lake sessions, 1 boat session. Obviously no certifications in anything other than the ADP card, and some of those topics are more of a familiarity than being fully certified to do in an independent course.
ADP is extremely tailored around diving, with a focus on shore diving, in the Southern California region. I don't think its the end all be all of instruction/diving, but I think its an excellent program for the region. My PADI AoW course was a laughable joke in comparison and done in the same region. The La County community is great, so great that I was silly enough to do their instructors course and am about 3/4 of the way done (but have been since March 2020....stupid COVID).
