What I would really like is for instructor to talk to proprective diver about the first class will really give then. what class people should take after that and the kind of diving that is available (for warm water , cold, cave tech,......) What skill they will need to improve during there diving life. ......
I'd like to add to the discussion about this comment too.
The prospective student doesn't know much about diving but what they DO know is why they are interested. It is not required by standards for instructors (or shops, which is where most students make first-contact) to talk about the student's motivations for wanting to learn.
Having said that, it is in the best interest of everyone, shop, student and instructor, to get those "dreams", "goals" and "motivations" out in the open before training starts. No scuba course is a one-size-fits-all affair. Even the basic open water course can be tailored to fit the particular mix of dreams, goals and motivations of a particular student. Smart instructors (and shops) will talk to the student about this openly and discuss how far they will come in the OW course openly. This is called "managing expectations" and is an integral part of delivering a good quality course. Never promise what you can't deliver and deliver whatever you promise.
In my day job this is a major part of what I do..... maybe 80%. So as a scuba instructor it's so ingrained into my DNA to do this that I would never dream of training someone without first knowing what they wanted to get out of it. Communicate, communicate, communicate.
Alas, for many students and many instructors, this is unfamiliar terrain and on both sides people can tend to operate by making assumptions. An instructor might feel shy about asking a student what they want incase they can't deliver, and a student might not feel comfortable talking about their dreams incase it sounds stupid. But it's EXACTLY this effect that results in so many instructors delivering quality that the student feels is under par and why so many students give up on diving after their basic training.
In my experience, going into this helps enormously. IIRC I wrote previously on this thread (at least I hope it was this thread) about how managing expectations can help both student and instructor. What I'd like to suggest on this post is that getting expectations out on the open is not ONLY the instructor's responsibility. As a student, if you're not telling your instructor what you want, then it's not entirely his fault for not knowing.
