Are t he Office for Students' standards of evidence appropriate? Why it matters for widening participation

This debate paper argues that the Office for Students (OfS) has adopted standards of evidence that are inappropriate. These standards offer a problematic typology of different evaluation types, present a flawed hierarchy, and over-prioritise experimental approaches. As the OfS uses these standards of evidence to guide the evaluation of widening participation (WP) activities, this risks misrepresenting the evidence base for different activities, and prioritising methods that may not be the most appropriate. The goal of developing explanations of how WP activities work in particular contexts requires a more nuanced approach to evaluation. Recommendations are made for future practice: the OfS should review its standards of evidence and there should be greater debate in this area, evaluation should assess how WP activities work in particular contexts, and practitioners should make use of theory-driven, qualitative methods.
