This document discusses approaches to establishing a quality culture within vocational education and training (VET) institutions. It outlines the methodology used in a study of 20 VET cases across 13 European countries. Common elements found include use of self-assessment and PDCA cycles to collect stakeholder feedback. Successful self-assessment requires staff commitment, involvement in identifying improvement actions, and using results to inform changes. External support structures can help by providing quality frameworks, indicators, data collection tools, and training for VET staff. The goal is a handbook and tools to help VET institutions strengthen internal quality management.
