Although it is clear that a comprehensive M&E system must eventually include both monitoring and evaluation, the initial aim has been to establish a foundation derived largely from surveys and monitoring information. To date, much of the focus in M&E has come from the global level because new global funding initiatives been launched and required rapid scale-up and the development of technical guidance, international standards, and indicators for monitoring progress and determining success. At the regional and country levels, the challenge has been to implement national M&E plans and systems within a context of overall low M&E capacity and a range of M&E needs.
