This guide by Rick Davies was originally developed as guidance for a workshop for project partners involved in Indonesian health projects. It offers advice on identifying and appropriately writing effective Lessons Learnt paragraphs. It gives a number of examples of Lessons Learnt and discusses their strong and weak points.
This page on UNICEF's website brings together a range of Lessons Learnt, best practices and innovations that have emerged from UNICEF's programs and evaluations over the past five years. It's purpose is to make these available so that external audiences, particularly development practitioners and country level partners, can benefit from these.
Monitoring and Evaluation NEWS, a news service focusing on developments in monitoring and evaluation methods relevant to development programmes with social development objectives that is managed by Rick Davies, have compiled a provisional list of Lessons Learnt resources. It includes general resources, as well as documents covering the identification and documenting of Lessons Learnt.
