I don't totally agree with this. You're learning to follow the structured program that each agency has developed.
This is true and is generally applicable to most agencies.
The most obvious example is, of course, PADI. What PADI instructors are taught is, quintessentially, just product delivery.
The curriculum is designed for a very standardised implementation and only requires the barest modicum of diving ability to deliver.
Alongside that delivery, PADI IDC also educates essential elements like; risk management, standards, administrative procedures and, naturally, sales technique.
It's very hard to fail a PADI Instructor Exam because one only has to deliver the product in a safe and standardised manner. The IDC prepares candidates to do exactly (and only) that.
To a greater or lesser degree, all agencies approach training this way. I've not found an agency that actually provides instructors with a formal academic syllabus that develops pure teaching skills and knowledge.
The biggest differential between agency instructional standards is their definition of diving competency needed to be an instructor. Basically, how good a diver one must be before becoming an instructor.
When the benchmark for this competency is low, it enables people to become instructors who can do little more than regurgitate student-level materials and have to rely upon inefficient practices (i.e. kneeling, over-weighting etc) to demonstrate skills.
Such instructors have zero experience from which to supplement training and no capacity to improvise and adapt training to best problem solve and overcome student learning difficulties.
When an instructor is limited by these competency barriers they only have two choices: (1) to aggressively develop themselves as educators or (2) to reduce their student training expectations in line with their own limitations.
So... zero-to-hero courses are entirely possible given a low expectation of initial diver-level competency in instructor candidates; a situation deemed 'acceptable' given that the instructor only has to provide product delivery and not teach diving.
The eventual teaching ability of that instructor can be defined post-qualification and depends on their non-diving transferable experience, ethos, motivation and intelligence.
I'd suggest that highly motivated, highly ethical and intellectually strong instructors are a rare demographic on zero-to-hero courses in the first place.
People possessing those positive qualities are more likely to consider investing more time and effort in developing pre-IDC, rather than post-IDC.
In short, if you're truly motivated to being a great dive instructor... you'll probably recognise that competency should occur before qualification, rather than vice-versa.
