This guide has been written to provide practical guidance and tools to evaluators and evaluation managers, to integrate humanitarian principles (HPs) into standard evaluations of humanitarian action, and thus to strengthen the attention paid to HPs in evaluations of international humanitarian action, particularly in situations of armed conflict. The UNEG Humanitarian Evaluation Working Group is piloting this guidance. They group is very eager to hear from evaluation managers and practitioners who are using it in their work. If you are using it and are able to provide some feedback on your experience, please email the coordinators of the UNEG Humanitarian Evaluation Working Group, Laura Olsen (laura.olsen@un.org) and Sara Holst (sara.holst@fao.org).
