As part of CEP’s role as a partner in CECAN (Centre for the Evaluation of Complexity Across the Nexus), CEP is carrying out a meta-evaluation of a sample of the evaluation projects it has undertaken over the last 10 years. The review will seek to learn the lessons from past policy evaluations, and the value of different types of approaches and methods used for evaluating complexity. This extensive meta-evaluation of projects will support CECAN’s initial scoping stage and provide critical insights in understanding complexity and developing new ways to measure the effectiveness of policies across the ‘nexus’. CEP’s Dr Clare Twigger-Ross and Dr Bill Sheate are joint project leads.
