Background: This study examines the engagement of knowledge users in knowledge mobilisation (KMb) research on Canadian K-12 teaching and education policy. Research on and around KMb has grown in the decade since this field was first assessed comprehensively. Thus, it is timely to re-evaluate if current knowledge producer-user relationships in KMb research feature the mediating variables or recursive elements promulgated as best practices in KMb research. Methods: A scoping review was conducted to identify the profile of knowledge users, map the engagement of knowledge users, and account for any changes to their roles in the research process since 2008. Twenty-eight relevant studies were identified. Contextual data and frequency of engagement with knowledge users were collected and analysed. Findings: Findings indicate that a diverse group of knowledge users are engaged in KMb research and draws on knowledge from various disciplines. A majority of the studies reported that knowledge users were engaged in at least two stages of their research process, with them most frequently engaged during the search and data collection phase of the research process. Discussion and conclusion: There has been an encouraging effort in building iterative producer-user connections with knowledge users being engaged, often repeatedly, across different phases of the research process. This indicates an increasingly collaborative model of soliciting user insights on the development and diffusion of research evidence. The review sets the foundation for potential future research on producer-user engagement and provides insights applicable beyond the Canadian K-12 education system.
