ESD is at a pivotal point in many school systems and the recognition of the role of policy and planning is clear with regards to how schools can be turned into “sustainable schools”. In response to the growing demand for infusing sustainability into education policies, curriculum and other support processes, this course examines the relationship between education policy, planning and ESD, using the UNESCO ESD Lens metaphor. The ESD Lens is focused on providing tools for reviewing educational policy and practice towards sustainability. To explore further this approach, the course focuses on participatory engagement and contextualization of the ESD Lens contents. The analysis is coupled with a series of strategies on how the ESD policy and practice might be better executed for reorienting schools towards sustainability. The overriding goal of the course is to help students develop a deeper understanding of the relationship between education policy and planning in the field of ESD, the institutional structures needed to support ESD policies; and the role of various actors and entities in shaping educational policy and change for sustainability.
