Our approach — LA LETTRE

The chain of proof

Each link builds on the one before. We skip no step — that is what makes the whole thing solid.

Link 1

Signing up

It all starts with a shared culture: you commit, you show up, you respect the rules of the game. The foundation on which everything else is built.

Link 2

The skill

We link each activity to a precise skill, described in a framework. No vagueness: we know exactly what we are working on.

Link 3

The real situation

The skill is demonstrated in a real, observable situation. That is where the difference between "knowledge" and "know-how" plays out.

Link 4

The authorised signatory

Someone from the right field observes and attests: a professional, a community mentor, a trainer, or a certifying body. Proof is worth as much as the person who signs it.

Link 5

The cumulative block

The proofs come together into coherent blocks, which can be accumulated over time. Nothing is lost.

Link 6

Recognition

At the end of the chain: possible access to official recognition, a training course, a validation of prior learning. The door that opens.

Four fields that sign

Proof only has value if it is signed by someone with legitimacy. We work with four complementary fields:

Professional — an employer or a supervisor, who attests to practical know-how in a work setting.
Community — a mentor, who attests to commitment and progress observed over time.
Socio-educational — a trainer, who attests to structured learning.
Regulatory — a certifying body or an examining panel, who ties it all to official recognition.

The non-negotiable ethical rule: we never lie about proof. An attestation describes what was observed — no more, no less. It is neither a diploma nor a professional title. It is an honest testimony, which is valuable precisely because it is honest.
