Purpose: This article explores the policy context in the UK around securing impact from academic research, particularly from the perspective of a social science education researcher. Approach: The article locates impact studies within debates about broader accountability frameworks. Insights from this literature are applied to a case study about Preventing Violent Extremism (PVE) policy. Findings: Linear models of 'impact' are problematic for social science education researchers (especially (ex) school teachers) for several reasons. First, research and impact may be intertwined, especially in broader development work with practitioners. Second, impact in schools and on learners is often difficult to measure. Third, it is not always clear how the research contributes to impact, as opposed to other roles or activities in professional communities. Implications: Formal impact case studies for institutional evaluation are likely to provide only a partial account of the myriad impacts (and attempts to secure impact) of a researcher.
