May 2018 – The authors of this article published in the Annals of the New York Academy of Sciences seek to build the evidence base for ECD in humanitarian settings. They reviewed the current state of implementation research for ECD programming (targeting children 0–8) in humanitarian settings, through a literature review and a series of key informant interviews. Drawing from existing frameworks of implementation research and the findings from their analysis, the authors present a framework for ECD implementation research in humanitarian settings and propose an agenda for future research.
