The Research Toolkit Learning Gain tool® is an interactive resource capable of assessing and measuring impact of training interventions.It uses pre- and post-activity data to explore impact from the perspective of the activity participant, school or stakeholder representative. This has been successfully used to assess change in provision in Hospital Trusts,examined successful elements of University Summer School programmes, and is currently being used as part of the evaluation strategy for a collaboration of 12 Higher Education institutions in West Yorkshire.Results, using this tool, are generally displayed visually as radar charts – aiding participants and programme management to quickly view impact areas.
