Two Models of Dive Instruction – What the Data Shows
Two Basic Philosophies
There have always been two competing philosophies in dive instruction. I have watched them play out across more than three decades in this industry and the difference in outcomes is stark.
The first model is built around speed and volume — what I have long called the “Seize a Dollar Now” approach. Get divers certified quickly, keep costs low, move on to the next student. Assembly line instruction, where the goal is throughput rather than competency. Agencies embraced this model aggressively beginning in the mid-1990s, shortening course requirements and shifting increasingly toward online and screen-based pre-training. The business logic was straightforward — lower the barrier to entry, certify more divers, grow the market.
The second model is built around competency — what I think of as the Sustained Excellence Approach. The fundamental truth of recreational diving is simple: people only do what they feel comfortable doing. It is true in the workplace, at home, and especially in recreation. An instructor’s job is not merely to certify — it is to expand the student’s comfort zone until being in the water feels as natural as sitting on the living room couch. You will never fully achieve that goal. But it remains the goal. Refuse the assembly line. Take the time to develop genuine water skills. Train divers who are comfortable, capable, and independent underwater. Accept that courses take longer and cost more. The bet is that a genuinely competent diver stays in the sport, keeps diving, keeps learning, and keeps coming back — because they are comfortable enough to enjoy it.
I have always taught to the second model. Across thousands of students trained from Thailand to Portugal and across North America — at every level from open water through instructor trainer — a sustained continuing education rate of approximately 75% tells me the approach works. Divers who genuinely learn to dive keep diving.
What the Research Is Beginning to Confirm
For years this was a philosophical argument. I had my data. The speed model advocates had theirs. We talked past each other at conferences and in the dive press and nothing much changed.
That is beginning to change — and the confirmation is coming from an unexpected direction.
In early 2026, neuroscientist Dr. Jared Cooney Horvath testified before the U.S. Senate Committee on Commerce, Science, and Transportation with findings that stopped me cold. For the first time in modern American history, the current generation scores lower on standardized cognitive measures than the generation before it. Memory, attention, executive function, literacy, numeracy — across approximately 80 countries using PISA data — the trend is consistent and it is going the wrong direction. Dr. Horvath identified screen-based learning replacing traditional instruction as a significant contributing factor.
I have been saying for twenty years that online pre-training was degrading the quality of students entering dive courses. I did not have Senate testimony to back me up. Now there is some.
The parallel research coming out of Scandinavia, Germany, and France tells the same story in student populations where digital-first instruction has been most aggressively adopted. This is not a fringe position anymore. It is showing up in the data.
The implications for our industry are direct and uncomfortable. We shifted toward online pre-training and abbreviated in-water instruction at roughly the same time screen-based learning began its rise. The students walking into dive courses today have shorter attention spans, reduced capacity for the deliberate repetitive practice that genuine water competency requires, and less tolerance for being told they need to do something again until they get it right. That is not their fault. That is the learning environment they were formed in.
The answer is not to further abbreviate training to match diminished expectations. The answer is to recognize what you are working with and compensate for it. Take more time, not less. Demand more repetition, not less. That is what professional instruction looks like in 2026.
What This Means If You Are Looking for an Instructor
The question worth asking is not which course is fastest or cheapest. The question is what kind of diver you want to be when it is over — and whether you want to still be diving five years from now.
I have never taught the fast model. I never will. The courses take longer, the expectations are higher, and a 75% continuing education rate across thirty-plus years of instruction tells me everything I need to know about whether the approach works. Competency is not a luxury. Underwater, it is the only thing that matters.
If that is what you are looking for, I would be glad to talk.
