In this article, the authors have chosen to inquire into a topic that has specific relevance to the status and inclusion of environmental education in the curriculum at a stage when the translation of policy into practice stands at the crossroads: the transition of environment as phase organiser to environment as integral to all learning areas. In education praxis, the translation of policy into practice is in the hands of educators and teachers (using the terminology as suggested in this article). The issues and challenges regarding the implementation of environmental education policy as experienced by educators and teachers are identified through examining this phenomenon as portrayed in two case studies where in-service education and training (INSET) in relation to environmental education occurs. This study is one of the first to provide a researched background that identifies issues and challenges that impact on the implementation of environmental policy in formal education contexts.
