The Evaluating Science Policy Practice Interface (ESPPI) Project aims to assess how far CREW is meeting its original three objectives, and to make recommendations to the CREW Facilitation Team (CFT) and the CREW Steering Group (CSG) for future improvements. This report is based on the views of people involved in CREW (researchers from the James Hutton Institute and the university sector, and policy / practice customers in the Scottish Government, SEPA and Scottish Water).
