Engage the standards

This page details the WorldSkills Occupational Standards (WSOS), specifying the knowledge, understanding, and skills that underpin international best practices in technical and vocational performance. These standards embody a shared global perspective on the work roles and occupations they represent in industry and business, supporting the preparation of students and apprentices for international competitions.

To assist educators in further and higher technical education, we have developed a suite of WorldSkills UK National Standards of Excellence, designed to bridge the gap between UK and international standards.
