Data sources

Last updated: 4 November 2026

SkillQuest's skills library is built in part from two public skills classifications. We have adapted both: skill names, descriptions, level descriptions and trait links in SkillQuest are our own, written from these sources.

ESCO

This service uses the ESCO classification of the European Commission.

SkillQuest uses an adapted version of ESCO v1.2.1. It is not the original classification, and the European Commission has not reviewed or endorsed it. ESCO is reused under Commission Decision 2011/833/EU on the reuse of Commission documents. Source: esco.ec.europa.eu.
