Various studies have investigated the views of higher education staff and students about sustainability, yet educational developer perspectives are under-represented in the research. This project gathered educational developer perspectives about sustainability in the curriculum. It sought to capture their views about a national sustainability policy; about the relationship between educational development and sustainability curriculum change; and whether sustainability should form part of their own roles. It was informed by the "theory of the second-best" and involved nine interviews. Educational developers raised concerns about the policy, whilst opinions about their own involvement varied. It is argued that policy should provide clearer statements about curriculum, and educational developers should be involved in its development.
