As Jeff points out the original question was concerning cert credit which "should" be based on whether or not being trained in one area covers all the requirements of the other. I say should because things aren't always done in a way that makes sense. As I see it there are 2 parts of this. The first is just a camparison of training standards and the second is the assessment of current skills. Obviously when issueing a certification today, I'm concerned with the knowledge and skill of the student today.
When I was in the military, I dealt with a number of different instructors. They had a curriculum to go by and lesson plans for each phase of training. This isnt just BUDS training, I also went through 2nd Class Divers School. The objectives for each portion were laid out and the Instructor told us what was required to pass, before we ever started the evolution. There were good Instructors and poor ones, so you just did the best you could with what you had at hand. Instructor choices were and are out of the question. Gee, thats kind of like College.
Some of us started commercial diving after we got out. A lot of guys went through a commercial diving school while in the military. I just went straight to New Orleans and found a job. Those guys came to work in New Orleans a few months later, so we were all in the same arena again. I also met commercial divers who couldnt swim, because you are basically an underwater mechanic and sometimes being in the right place at the right time has its advantages.

With some agencies you go by the book and have no other choice so if the agency doesn't have provisions for a cross over then there won't be one. Some agencies give the instructor a little more latitude to credit a student for previous training, experience or skill. With IANTD, for instance...if a former or current military diver came to me and I assessed his skill and knowledge to be at whatever level, rather than making him go through an OW class, just because I don't see the question specifically addressed in the printed standards, I'd call the office or shoot an email to Tom to see what he had to say.
Ive been a PADI Course Director for 20 years and while the Instructor is important, so is the Dive Store. People have agendas and timeframes to get certified by today. If an Instructor gets sick or injured then another Instructor can step in to take his place, as long as there is a backup plan to help and a curriculum is set so skills can easily be assessed. At a store this is usually much easier.
I want to make sure people understand the physics of diving, because this is science in practice. Physiology and Dive Tables are of primary concern, so students understand what happens to their body underwater and more than just a cursory overview of how to handle the depth and time factors. Computers and table knowledge are just backups to your brain. Equipment concerns can be addressed much easier through a store, since access to new stuff is more prevalent. Currents, tides and other geographical concerns also need to be addressed. Those will change, depending upon where you live and dive.
I guess I could start my own agency and make it so hard that Id get very few people to become Instructors. My point is the more people who are certified, the more equipment that is sold and the better the equipment gets. The manufacturers are able to research and improve equipment, so they continue to give rise to the forefront of technology. Without the Dive Store, diving would be in a state of flux. In case you havent noticed, this is a very equipment intensive sport.

Just as a point of reference it's often not that easy for instructors to cross over from one recreational agency to the other either. They YMCA, for instance wants you to start with their rescue (slam?). They don't care if you're full cave, advanced trimix and have been to 300 ft depth in a cave and teaching for 20 years. When, as a PADI instructor, I crossed over to IANTD the IT beat the hell out of me. LOL
Contrary to what some people on this board might think, Im not married to PADI. As I said on this thread, I just became an IANTD Trimix Instructor. This is within PADI Standards. I have seen how Instructors from other agencies teach and while there are good and bad ones in all walks of life, I dont like having a course shortcut because I supposedly know the material. You dont know what you dont know! That didnt happen with IANTD, nor when I teach a PADI course. I teach classes so people can gain the most knowledge, skill and most importantly fun from it. Getting a card, although a customers primary purpose for coming to my store has to be the carrot, the training to accomplish that goal needs to be adhered to at all times.
When I took a SLAM Course years ago, I asked one of the Y Instructors a question in regards to how to accomplish something. Before I asked that question, I already knew the answer, but his lecture was misleading people. His response had the IT at the course jumping in to revise the answer, before he had egg all over his face. I was already a Public Safety Scuba Instructor. The ITs were very conscious of how things should be handled. The interesting part was going to a cow pond for the open water and getting my boot sucked off in 3 feet of muck. Yes, I found it.
