It gets worse and worse as time goes by and we see more cave instructors who really aren't even good cave divers. The NSS-CDS/NACD pipeline requires an internship and requires prospective cave instructors to watch several classes be taught and requires they teach a few classes while being observed. This route takes many months and often over a couple of years minimum to achieve full cave instructor status. This is how the NSS-CDS and the NACD have maintained the highest of standards of cave diver training. Our cave divers do not work on their knees.
A few months ago a guy approached one of the NSS-CDS instructor sponsors about becoming a cave instructor. The sponsor explained the required route and the time requirements. He also explained that there are no monetary requirements. NSS-CDS instructors may not charge for training instructor interns
A couple of weeks later this same guy contacted the NSS-CDS instructor sponsor and told him he did not now need the internship program nor did he need an NSS-CDS instructor sponsor. This guy told him he had found a cave instructor trainer(IT) with XXX and had spent the prior weekend with the IT auditing a class. He was able to pay the IT and was certified as a cave instructor.
This is at least part of why we are seeing substandard cave divers. Someone in an earlier response suggested reading the sticky on how to find a good cave instructor.
