The guideline uses state-of-the-art evidence to identify effective policy options to strengthen community health worker (CHW) programme performance through their proper integration in health systems and communities. Successful delivery of services through CHWs requires evidence-based models for education, deployment and management of these health workers. The guideline is intended as a tool for national policy makers and planners and their international partners to use in the design, implementation, performance and evaluation of effective community health worker programmes. It contains pragmatic recommendations on selection, training and certification; management and supervision: and integration into health systems and community engagement.
