This document summarizes the formative evaluation approach for the CETL (Centres for Excellence in Teaching and Learning) programme. The evaluation will have three main goals: 1) Explore theories of change embedded in the CETL programme and tell stories of what works well through appreciative inquiry; 2) Identify promising and effective teaching practices and their impact on student learning and institutional culture; 3) Provide lessons learned and implications to inform future adjustments to the CETL programme strategy. A mixed methods approach will include interviews, case studies, surveys, and collaborating with local evaluators to understand the programme's effects on various levels.
