Well, we are getting into a different question now, aren't we? Let's see how that would happen.ahhh...blame the instructor again. If the updates, forums and continuing education of instructors was important, beyond making it available should the agency not also make a certain degree of CE/updates mandatory? Why would they allow a instructor with no updating of their professional qualifications to teach?
PADI puts out a quarterly professional journal that goes over training issues. It has quarterly training updates as well. It sends out a new manual every year for instructors to read. You can go to the web site and read materials on your own log in or on someone else's login. You might be an employee of an organization that keeps its employees informed of all these issues. For my first half dozen years as a professional, the Course Director where I worked kept us all update on new information.
In other words, it is very possible that an instructor has read all the information and gotten well updated without PADI having had a clue that it happened. It would take a monumental and quite costly effort to give annual exams to instructors to make sure they are keeping up with things.
I had a career in public education. Every state has laws designed to make sure that teachers stay current with changing information about teaching. That is a complete joke. In a large part of my career, my job was to give teachers that updated information. They are largely immune to it. I would bet that if I gave a test on current learning theory to a random collection of teachers, fewer than 10% would pass.
