Threads like this often devolve into the ways that a dive agency should improve the quality of its instructors through some sort of oversight. What the arguments boil down to is this: "Dive agencies should guarantee instructor quality by behaving more like the public education system." As a career teacher and school administrator, I know something about that. Let's take a look at that. Each state is different, but this generally sums things up:
- In college, prospective teachers must take a number of courses teaching instructional methodology.
- Prospective teachers must undertake internships and student teaching experiences.
- Prospective teachers must take state-wide exams.
- Once hired, new teachers are required to participate in new teacher mentorship programs.
- New teachers are required to undergo intensive annual evaluations for their first three years.
- Once past three years, teachers are usually evaluated by a professional administrator at least every other year.
- Teachers are required to participate in continuing education classes, usually every 5 years.
All of that costs many, many thousands of dollars per teacher. with that money coming from taxes and the teachers themselves. How would such costs be borne by the scuba industry? Now, is anyone going to argue that it ensures that all teachers are top quality?
