How certification works

A score is only as good as the system that stands behind it. This is ours — in full, with no secrets: eight rules that make every Impact Score a proof, not a promise.

1 · Who certifies

The Impact Controller: selected, trained and authorised directly by Simbial, always independent from the project being certified. This is no ordinary reviewer: it is the profession of trust, with a role earned through references and competence — never through registration.

2 · The rule that matters: never write numbers

The Controller never enters a score. They validate the evidence — documents, readings, photos, exports — and the calculation always remains automatic: physical indicators multiplied by public, versioned coefficients. No human hand can adjust a score.

3 · Mandatory evidence and standard checklists

Each indicator requires its own evidence, and each type of evidence has a versioned verification checklist: what to check on a utility bill, a production log, a training certificate. The Controller follows a procedure, not a free judgement.

4 · Anomalies don't slip through unnoticed

The AI compares every value against the register's history: an anomalous deviation is flagged, and a flagged piece of evidence can only be approved with a written note from the Controller. The system forces a second look exactly where it's needed.

5 · The dual signature, where it matters

The first assignments of every new Controller and the certifications of the largest contracts require the co-signature of a second Controller. Four eyes on the points where a mistake would carry the most weight.

6 · Sample audits, paid

Every quarter the system randomly selects a portion of closed certifications and assigns them for blind review to another Controller — paid to do so, because quality control is work. Discrepancies feed into the precision rating of the certifying Controller.

7 · Independence and rotation

A Controller never certifies programmes they have worked on, and they rotate: a maximum of three consecutive years with the same client — the auditor's rule. Trust doesn't wear out through habit.

8 · Confidence levels: honesty is in the number

When evidence is missing, nothing disappears: the indicator stays at its confidence level — estimated, assessed, validated, or certified — and the score speaks for itself. An honest number beats a pretty one.
