SCI (Skill Credibility Index)

Definition

A computed score representing how credible a person's skill claim is, based on accumulated peer session evidence. SCI is not a test score -- it is derived from real interactions observed by peers over time.

Why it matters

Traditional credentials (degrees, certificates) prove attendance, not ability. SCI solves this by quantifying demonstrated competence through evidence that employers and collaborators can trust.

How Lemma uses this

Every peer session on Lemma generates evidence events that feed into the SCI computation. Your SCI score updates automatically as you complete sessions, building a verifiable track record.
