This tool is a living document that provides guidance on good partnership practices that promote strong relationships between civil society organizations and government representatives on engaging men and boys in gender equality and sexual and reproductive health and rights (SRHR). Its goal is to strengthen these partnerships in order to enable the scale up and/or institutionalization of evidence-based approaches to engaging men and boys. This tool, organized by stages of the program cycle, can be used to highlight key entry points to gain, strengthen, and maintain government support for CSO-implemented programs. It provides guidance on how CSOs can serve as more effective partners in these collaborations.
