Two Models of Dive Instruction – What the Data Shows
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. Instructors who favored the speed model had their data points. Those of us who favored the competency model had ours. The debate continued.
That is beginning to change.
In early 2026, neuroscientist Dr. Jared Cooney Horvath testified before the U.S. Senate Committee on Commerce, Science, and Transportation presenting evidence that for the first time in modern American history, the current generation scores lower on standardized cognitive measures than the generation before it. Drawing on PISA data across approximately 80 countries and longitudinal measures of memory, attention, executive function, literacy, and numeracy, Dr. Horvath identified screen-based learning replacing traditional instruction as a significant contributing factor.
His testimony is consistent with parallel research emerging from Scandinavia, Germany, and France showing similar trends in student populations where digital-first instruction has been most aggressively adopted.
The implications for dive instruction are direct. Our industry shifted toward online pre-training and abbreviated in-water instruction at roughly the same time screen-based learning began its rise. The students entering dive courses today have been shaped by that environment — shorter attention spans, reduced capacity for deep skill development, and less tolerance for the deliberate repetitive practice that genuine water competency requires.
This is not a criticism of students. It is a description of the learning environment they were formed in. The responsibility falls on instructors to recognize this reality and compensate for it — not to further abbreviate training to match diminished expectations.
What This Means If You Are Looking for an Instructor
If you are selecting a dive instructor — for yourself, a family member, or your agency’s dive team — 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.
Competency is not a luxury. Underwater, it is the only thing that matters.
I have never taught the fast model. I never will. The courses take longer, the expectations are higher, and the results speak for themselves. If that is what you are looking for, I would be glad to talk.
