Professional teaching associations in Australia and abroad have been developing teacher and/or teaching standards and associated professional learning and assessment models in the key discipline areas since the 1990s. In Australia, a specific intent of this approach is to capture and recognise the depth and range of accomplished educators' teaching. Despite the increasing work in this area, there has been a dearth of discussion about teacher standards in environmental education and no previous attempt to research and/or develop professional teacher standards for environmental education in Australia. This paper discusses the history of teacher standards in Australia, and considers the implications for the development of teacher standards in environmental education. In doing so, we present a research-practice model that is currently being piloted in Victoria for developing accomplished professional teacher standards and learning in environmental education with and for accomplished Australian primary and secondary teachers.
