It seems to me that diving in general has a pretty high attrition rate. I'm not in the industry so I haven't bothered to find the statistics, but I was under the impression that the number of people who go on to be regular divers is but a small fraction of the number who either initially do a DSD or get their OWD cert.
I wonder how this compares to % retention amongst people who try golf, tennis or skiing?
This forum tends to draw avid divers, so some may unconsciously assume anyone who got down on a scuba dive with a pretty reef and nice conditions should be enthralled and want to start saving for dive trips (or local diving in California, Florida, etc...), and if they don't, the course must've been bad. But we aren't representative of the general public, or general vacationers.
One practical intervention you might get started is a pre-course questionnaire asking some questions such as whether the student is interested in a once-and-done bucket list experience, loosely interested and unlikely to get serious but who knows, or thinks this might just be a new passion. My wording needs work, but you get the idea. The goal is to get data on what % of DSD students are potential ongoing divers; without that, it's hard to judge what to make of claims that retention is too low.
Most parasailers won't become hang glider enthusiasts no matter what you do.
