This paper reports on an interview study of eight teachers engaged in the Sustainable Schools Programme (SSP) in New South Wales, Australia. Teacher views on key components of education for sustainability are compared with the underlying socially critical approach of the SSP and the NSW policy on environmental education. Their views on active student engagement in the SSP are also revealed. The findings, which indicate that some teachers hold a view of education for sustainability consistent with key assumptions inherent in the SSP, are encouraging. However, remarks by most of the teachers suggest that wider professional support is needed if the SSP, and indeed the NSW policy on environmental education more broadly, are to be implemented as intended.
