The Humanitarian Evaluation Working Group (previously the Humanitarian Evaluation Interest Group) works to advance humanitarian evaluation within the UN.

In 2024, it published the Guidance on the Integration of the Humanitarian Principles in Evaluations of Humanitarian Action. This guide provides practical guidance and tools to evaluators and evaluation managers about how to integrate humanitarian principles (HPs) into standard evaluations of humanitarian action. The group is currently focused on piloting the Guidance with the intention of updating it in the coming years.

In 2018 the group published The Humanitarian-Development Nexus - What do evaluations have to say? Mapping and synthesis of evaluations and in 2016 Reflecting Humanitarian Principles in Evaluation.
