Monitoring is a routine process of documenting program activities, usually for the purpose of ensuring
that programs are doing what they intended to do. Data collected usually indicates that something was
done or not done, how much was done, and who was involved.

Evaluation uses a variety of data to make judgments about the quality of the program. Sometimes, this
includes whether the program was effective in producing the intended outcomes (this is called impact
evaluation). Evaluation data goes beyond “what” and “how much” questions to ask why and how the
program worked.

Monitoring and evaluation work together in that evaluations often rely on data collected as part of
monitoring, monitoring results may inspire evaluation questions, and evaluation findings may result in
new categories of information to monitor.
