Development of practical methods and tools to support rigorous M&E systems is a FANTA trademark. FANTA assisted USAID’s efforts to collect and analyze the best available data to rigorously and credibly support programmatic decision making, systematic learning, and documentation of program effectiveness. FANTA developed and tested several food security and nutrition indicators, many of which are now used globally, and created guidance documents to support data collection for these indicators. We helped determine M&E best practices and policies and provided detailed guidance on complex M&E technical activities, both at the global level and directly to national and local governments.
