The UNESCO Operational Strategy on Youth for 2014-2021 (OSY) guides the Organization’s work on Youth in the different strands of work within UNESCO’s mandate. It aims to ensure that young women and men are engaged in policies and programmes that affect them, and that they lead actions to promote peace and sustainable development in their countries and communities. The Mid-Term Review of the OSY was intended to help shape the further development and implementation of the UNESCO Operational Strategy on Youth, and relevant programming, with a view to increasing its operationalisation and impact.
