Method

Most "train the trainer" isn't training anyone.

Ask what it means and you'll get the same answer: take someone who knows the subject, walk them through the slides, maybe do a dry run. They're a trainer now.

Call it what it is: content transfer. It's efficient, it scales, and it's where most organizations stop.

One level up is methodology transfer. You stop handing over slides and start explaining the structure: why this exercise comes before that concept, why there's a silence at minute twelve, why assessment runs through the session instead of sitting at the end. Rarer, but it exists. It's what I'm building at Scaleway.

Then there's a third level almost nobody works on in corporate training, though it's been central to teacher education in France for decades. Posture. Not what you do in a session — who you are when the session stops going to plan.

The level you can't hand over.

Here's the paradox. The trainers who read a room best are the ones least able to explain how they do it.

There's a well-documented model of competence with four stages, ending in unconscious competence — you do the thing well without thinking about it. That's the goal everywhere else. In teaching, it's a trap: to transmit something, you first have to make it visible again, which means traveling back from stage four to stage two. You have to remember what it felt like not to know. It's disorienting, because the whole point of stage four is that you stopped paying attention.

Take the most ordinary moment there is. You ask a question and the room goes quiet. The problem isn't the silence — it's that you don't know what it means. Are they thinking, or are they lost? Same silence, opposite meanings, opposite responses, and you have about two seconds. Push, or wait. Rephrase, or say nothing.

Nothing in the content or the plan tells you which. Experienced trainers get it right most of the time and can rarely say why.

What I've found so far is that it starts with naming the invisible — putting words on decisions that were never conscious, so they can be discussed at all.

What it looks like when it's done.

A school hired me to teach teenagers to program. What they actually needed was someone to rebuild the curriculum — three years of material with no real progression, not across a year and not across the three. Topics showed up because they existed, not because anything before them made them necessary.

I spent the first year rebuilding it from zero: deciding what to teach, in what order, and what to leave out entirely. The second year, with the progression in place, it held.

And it's the work I'm doing now at Scaleway, one scale up again — building the program that teaches engineers to teach, and designing the trainings myself so there's something to point at.

The work.

Three shapes it usually takes.
