Definition - Program evaluation is a systematic way to collect, analyze, and use data to answer questions about a program so that the program can be improved and its effectiveness documented.
Description - Program evaluation answers questions about a program’s process and its outcomes. Process evaluation questions focus on describing the activities conducted in support of the program’s objectives and the extent to which the program was implemented as planned. Answering process evaluation questions while a program is being implemented also allows us to identify problems and make necessary changes while the program is still operational. Example process evaluation questions include the following: What activities were implemented in support of the program? What was the reach of the program? Did the target audience react favorably to the program? How many materials were developed and distributed throughout the program? Under what context and environmental factors was the program implemented? What lessons were learned from the program implementation?
