As the Knowledge Translation (KT) field advances, there is an increasing need to identify priorities to help shape future directions for research. An important source of KT priorities is ‘experts’ who are well-established researchers and practitioners. Another potential source for identifying priorities is trainees. Given that many KT trainees are developing their programs of research, understanding their main concerns and priorities for KT research and practice is critical to supporting the development and advancement of KT as a field. The purpose of this study was to identify priorities for research and practice in the KT field from the perspectives of KT researcher and practitioner trainees.
