PADI has a number of options leading up to expulsion. I can't believe they will do nothing. We have had a number of threads in recent months about PADI instructors being expelled, and sometimes quite quickly.
In this case, there are a number of issues that PADI will be concerned about.
Obviously, the shoddy/non-existent adherence to standards will be addressed. They'll probably canvas a few of the instructor's other ex-students, to see if it is a trend, or a one-off incident. They'll also ask the instructor directly. My assumption is that this issue, unless blatant and sustained, would lead to nothing more than a 'slap on the hand' - or, as PADI term it something like '
having to sign a statement of confirmation', promising not to do it any more...
Further repeat offences might lead to 're-training'... pay PADI some more cash to sit-in on elements of the IDC or re-take an IE. Blow it again after that... and you might worry about your certification status as an instructor.
No safety issues are presented in this case - so PADI probably wouldn't cut the instructor loose out of any liability fears.
The other issue (
which a cynic might say PADI would be more concerned about) is that the instructor wasn't supplying the proper PADI materials for the course. This costs PADI money - and is something they've instigated numerous standards and updates to emphasize. Seemingly more so than any communication effort made to improve the quality of courses taught. If the student didn't receive materials, then the instructor probably wasn't
buying the materials from PADI. That hits profitability and PADI don't get their "fair share" of the loot. They'll slit throats for less..
My membership/status was once 'threatened' by PADI. It was very serious. I had mistakenly believed that (as a PADI Pro) I could use their logo on my website.
Bam! Nasty email threatening expulsion if I didn't remove the image immediately. So... yes, they can "move pretty quickly" if motivated to do so. We can all guess what those motivations are....
