Purpose: The purpose of this paper is to present a professional development experience for higher education academic staff within the framework of an international Tempus project focused on reorienting university curricula to address sustainability. The project included revising curricula to phase sustainable development principles into university courses. Design/methodology/approach: A qualitative approach was used to examine perceived professional development. Focus groups have been conducted with the academic staff who participated in the project. Findings: The results provided evidence that revising their curricula offered the participants an opportunity to discuss different principles, teaching methods, didactic processes and practices in Education for Sustainable Development (ESD). Several strategies emerged during curricula revision such as a positive attitude towards meta-cognitive strategies and a goal-oriented approach to curriculum planning. Moreover, the project induced the academic staff to reconsider their teaching methods. Research limitations/implications: The main limitation is the restricted generalisability of the findings, because of the small number of participants. Further research is needed to confirm the theoretical model that emerged. Implications of the results for professional development and the induction of change in academic staff are also discussed. Originality/value: There is little information about training experiences for enhancing professional development in academic staff using ESD principles, and this study provides a starting point. According to the results, the project had an impact on the participants' attitudes, teaching principles and methods, course design skills and assessment approaches.
