Bali, Day Eight
On August 10, in Bali, the eight days of the first international youth coach course run by World Aquatics came to a close. Eighteen coaches from twelve countries sat down with the final evaluation sheet. Of them, 94% wrote that the course exceeded their expectations, and satisfaction with the lecturer matched satisfaction with the classroom sessions.
The most notable thing about this course is not the 94% figure. It is the word "first." This was the first time World Aquatics merged two branches — pool swimming and open water swimming — into a single international youth coach training program. Twelve countries, seventeen funded scholarship places, eight days, and an island with an ocean for a practical room.
I read this as a data person, not a media person. And I see two stories layered on top of each other: one about an international federation's effort to build a system, and one about how we tend to measure the wrong thing after we build it. At Lach Tray, I learned to read injury from the first numbers. But I also learned the opposite lesson: not every beautiful number is a sufficient number.

Context — a classroom beneath the competitive pyramid
World Aquatics runs a tiered coach certification system. There is the Age Group Coach tier, the Youth Coach tier, and the Performance Coach tier. The Bali course sits at the Youth Coach tier. Choosing this tier, rather than the Performance tier, reveals the strategic priority: broadening the coaching base at grassroots level, not refining at the elite peak.
The delivery structure is blended. Participants study theory online through World Aquatics' CORAL e-learning platform, then attend in person for practicals and discussion. This is a low-marginal-cost model at scale: a digitized lecture can serve thousands of coaches in federations lacking the resources to run in-person courses. When you want to change coaching quality globally, you cannot fly country to country. You have to travel by digital platform.
In terms of position within the system, this course sits at the development layer, beneath the competitive pyramid. Above it are the Olympics, the World Championships, the World Cup, then continental and national events. But it is precisely this development layer that produces the coaches, and those coaches produce the athletes of the future. This is the talent-supply layer for the whole pyramid. It is not glamorous, but it is the root.

What sets the Bali course apart is the practical component. Practicals take place in the ocean, not a pool. Participants are trained in pack swimming, drafting, feeding, and starts. These are open-water-specific skills that a purely pool-based coach course would never touch. The organizers also elevated safety and risk management into a headline topic, on par with technique and tactics.
The lead facilitator is Mel Tantrum, national head coach of the Australian Paralympic swimming program, and lead developer of World Aquatics' open water coaching certification. One person standing both at the performance peak and at the development-certification design stage. This dual role says one thing: knowledge from the elite peak is transferred directly to the base, rather than routed through many intermediate layers.
Core analysis — what is actually taught, and where it sits in the bigger picture
I want to separate two things that media often merge into one. First, the technical content of the course. Second, its systemic meaning. These two have very different values, and mixing them is the fastest way to misread an educational event as a performance event.
On technical content, the course does not teach athlete stroke improvement. There is no stroke analysis, no stroke-rate data, no distance-per-stroke. There is not a single split time anywhere in this story, because the subject of the course is not the athlete but the coach. What is taught is coaching methodology: season planning, session design, long-term athlete development, building positive learning environments, and communicating with young athletes.
This is where I want to pause a little longer. When a federation says it is "raising coaching quality," it is usually not talking about teaching coaches a new movement. It is talking about teaching coaches how to think. The difference between a coach who copies someone else's session and a coach who understands why that session exists lies in reasoning, not in limb technique. And that is precisely what the "theory then practice" structure tries to create.
The open-water-specific part is where the most clearly technical content lies. Pack swimming is a survival skill when you are in a mass of hundreds starting together. Drafting is the art of saving energy by using the swirl zone behind the person ahead, a skill that, done wrong, can cause you to collide and lose direction. Feeding is a logistics problem mid-race, where you must drink or eat without breaking your breathing rhythm. An open-water start is not a dive from a block, but a technique of launching from shore or swimming from an in-water start line, where chaos is the default, not the exception.
These four skills are what I call the course's transferable core. They are not new technical inventions. They are skills that have existed in open water for a long time. But putting them into a formal federation certification program is a meaningful step: it turns knowledge scattered across a community into a standard that can be taught and tested.
On pedagogy, the Bali model is blended and applied: a classroom theoretical framework, then practicals in water and on the ocean. This "theory to application" loop is mainstream good practice in coach education, not a novel method. I say this not to diminish the course, but to position it correctly. A good program need not be a revolutionary one. It only needs to do what it claims to do.
What the course genuinely targets is a specific gap: coaches' lack of confidence in delivering open water sessions. By the facilitator's account, the highlight of the course was the speed of participants' confidence growth when they ran ocean sessions. This is a notable signal. It says the bottleneck of open water is not the athlete's stroke technique, but the coach's delivery capability. You can have a good swimmer, but if there is no coach willing and able to run a safe ocean session, the sport will not grow in that place.
When I lay this certification structure on the table, I see a deliberate architecture. Age Group, Youth, Performance — these three tiers form a development ladder. Each tier is a step on the same path. That means World Aquatics is not merely training coaches, but building an occupational classification system for the coaching profession in swimming. And once you build a classification system, you can assure quality, you can move coaches between countries, and you can create a shared standard.
On the national picture, the course exposes a rarely discussed reality. Australia, through Tantrum's role, holds de facto technical leadership over open water coach certification. An Australian designs the certification, an Australian teaches the first course, and that certification is issued by an international federation. This is a one-way knowledge flow from Australia to the world in open water. But at the same time, the organizers emphasized a balancing message: "no single country or system has all the answers." This diplomatic message shows World Aquatics is deliberately decentralizing open water expertise rather than anchoring it in one nation.
Twelve countries in one classroom, seventeen scholarships, and a tiered certification program — that is a deliberate geographic-expansion strategy. The goal is not to serve wealthy federations, but to extend the base of certified coaches into developing federations where open water infrastructure is nascent. And the tool for doing that, once again, is the CORAL e-learning platform.
The contrarian angle — 94% is not evidence, and that is the real problem in this story
This is the part I want to dissect bluntly, because I have spent much of my career reading numbers that stand alone, and I know how dangerous they are.
The only quantifiable number in this entire story is the 94% satisfaction rate, with a sample of 18 responses. In other words, of 18 evaluations, roughly 17 people said the course exceeded expectations. That is a high number on the surface. But it is a small number, self-reported, from a small group, from a single edition. There is no control group. No longitudinal follow-up. No independent assessment.
I want to be clear so no one misunderstands me as attacking the course. I am not attacking the course. I am attacking the way a satisfaction rate is used as evidence for a far larger claim. The larger claim is: coaching quality globally is being raised. And 94% satisfaction cannot prove that.
At Lach Tray, I once saw reports with high satisfaction rates while a team's injury days kept rising. Those two numbers do not contradict each other; they are simply measuring two different things. Satisfaction measures participants' perception right after the event. Raising coaching quality measures athlete outcomes years later. One is an input, one is an output, and the gap between them can stretch from two to eight years.
Three factors make this 94% figure need more cautious reading than it is given.
First is the small, self-selected sample. Eighteen people is far too small for any meaningful statistical conclusion. At this sample size, a few negative responses could pull the rate down very fast, and conversely, the absence of any negative response may simply reflect the amicable atmosphere of a small, eight-day course.
Second is courtesy bias. In a small, funded course with a famous facilitator, participants tend to rate higher than reality. This does not mean they lie. It means the context creates a higher satisfaction floor than the course could achieve if evaluated under more neutral conditions.
Third, scholarship funding removed an important dissatisfaction factor: cost. Seventeen of eighteen participants paid nothing, or very little. When cost is no longer a barrier, one of the most common reasons learners become dissatisfied is removed from the equation. This makes the satisfaction level a poor indicator of willingness-to-pay in an unfunded rollout.
There is one more detail I consider the most important in the entire feedback section: the participants themselves requested more practicals, more race simulations, more real-life coaching scenarios, and more discussion time. This is a constructive signal, and it has high diagnostic value. It says the practical component was valued but supplied less than demand. In other words, the first edition skewed theory-heavy relative to learner appetite. This is a common finding in first-run blended courses.
On systemic risk, I see three points to monitor.
First, the sustainability of the format. This is the first merge of swimming and open water, so the model's durability, repeatability, and the recognition of the certification across federations are all unverified. A first edition that succeeds on satisfaction does not automatically become a global program.
Second, the output-measurement gap. The article itself sets the ultimate measure: what coaches take back to their athletes and programs. But the article provides no data on that measure. This means the program's true ROI is currently unmeasured. A program evaluated on inputs but not on outputs is a program running on faith.
Third, resource sustainability. Seventeen scholarships depend on World Aquatics' budget. If that funding stream changes, the equity-of-access model feels the pressure first. And this is why the CORAL e-learning platform matters so much: it is the only lever that can expand reach without increasing the scholarship budget proportionally.
I want to close this section with a comparison I have used many times in my career. Kane 2026 was not a curse, but simple subtraction. When you remove the noise — luck, psychology, timing — you are left with a measurable overload problem. The same applies here. When you remove courtesy bias, the scholarship effect, and the small sample size, the 94% figure does not disappear. It just shrinks to its true size: an early positive signal, not evidence of outcome.
Why this matters more than it appears
There is a reason I spend so much time on a story with no athlete, no medal, and no record. The reason is that this development layer is where the future of swimming is decided. The coaches who left Bali on August 10 will return to twelve countries, and over the next few years, they will be the ones designing sessions for thousands of young athletes. If the course works, the effect ripples exponentially. If the course only creates a good feeling without creating capability, the effect dissolves within months.
And here is the point I want to stress: the real bottleneck of open water in many countries, including Vietnam, is not the athlete. It is the coach. We have the sea. We have athletes willing to get in the water. But we lack coaches trained to run a safe ocean session, to read currents, to manage risk, and to teach pack swimming and drafting correctly. A global certification program focused on exactly that bottleneck is a signal worth watching, even when its data is thin.
There is a safety dimension I do not want to skip. The fact that organizers elevated safety and risk management into a headline topic shows open water coach education is partly driven by liability. Federations increasingly require open water certification as a condition of sanctioning events. This is a strong driver, and it may explain why World Aquatics is investing in this area now.
Empty stands, the golden rule bent, and the body pays. I once wrote that line about football returning after the pandemic. Here there is a similar logic, but at the organizational layer: when there are no certified coaches supervising, safety rules on the ocean bend, and the ones who pay are the athletes. Training coaches, in the end, is also a form of injury and accident prevention at the system level.
Looking forward
There is one thing I take from this entire story, and it is not a conclusion about the course. It is a question about how we measure the value of system-building efforts.
Every fall has a graph, and every graph has a break point. For a coach education program, the break point is not the satisfaction rate right after the course. It lies two to eight years later, when the first generation of athletes trained by these coaches enters the race. That is when we will know whether Bali's 94% was a real beginning or just a pleasant moment.
The number is silent, but its sequence always knows how to tell a story. The sequence here has only just begun. Eighteen evaluations are the first chapter, and it is a fast read. The chapters that follow — the coaches returning home, the first ocean sessions they run on their own, the young athletes who learn to draft and feed correctly — are the ones that decide where this story ends.
I will not rush a conclusion. I have never been the first to champion a new direction, and I will not be the first to bury it either. What I do is record the numbers, record their sample, and wait to see whether the second edition can repeat that 94% — and more importantly, whether anyone bothers to measure what lies behind the number.
