This resource guide provides information on how the United States Agency for International Development (USAID) sectors, missions, and staff can integrate child, early, and forced marriage (CEFM) prevention and response into their programming. The guide provides both the rationale of why and approaches to how USAID’s efforts can address CEFM. In addition, Banyan Global’s proposed child, early, and forced marriage monitoring and evaluation (M&E) indicators allow users to track changes in the status of women and girls in a particular country, as well as the impacts of a specific program. Beyond simply disaggregating by sex, these proposed indicators assist in capturing intermediate and long-term outcomes and enable implementers to select indicators that are most relevant to their work. Collecting data related to these indicators can enable implementers to track their progress, adjust programming for greater impact, compare the effects of their program to that of other programs, communicate impact, and attract funding.
