The Happy Museum Project are pleased to announce the publication of our second  Learning and Evaluation Report (Sep 14) . One of the principles of Happy Museum is to ‘measure what matters’, and the report was undertaken in that spirit.It is about learning as much as advocacy, and so explores challenges openly. It aims to find out about the process and the purpose of change in a peer-led national programme and for museums re- imagining their role.  The report expands on our earlier Learning & EvaluationReport (Sep13)
