A monitoring plan defines how progress on activities and expected results are measured. A monitoring plan is used to track the activities and accomplishments of a PHE program—allowing beneficiaries, project managers and donors to determine  the program’s success in meeting its goals and targets. An evaluation uses data-driven results to more comprehensively assess how well programs are achieving expected outcomes. In USAID funded programs, a monitoring and evaluation or M&E plan not only assesses how well program activities are leading to intended results, but also describes how the monitoring information will be used to learn from experience and how lessons learned will be shared. USAID has developed detailed guidance and training materials for PHE projects, as related to M&E, those documents can be found in this section. Examples of program evaluations can be found in the section "Current PHE Programs", "Country / Regional Experience", while broader studies that used additional methodologies are found in "Global Analysis and Assessment".
