خلاصه	Field-based program evaluation is an applied research method that assesses the implementation, outcomes, and value of a program by collecting data directly in the natural setting where the program operates. Rather than relying solely on administrative records or remote surveys, evaluators embed themselves in the field — observing activities, interviewing stakeholders on-site, and reviewing context-specific documents — to produce evidence-grounded judgments about program merit and worth.	Participatory program evaluation is an applied evaluation approach in which program stakeholders — staff, participants, funders, or community members — are actively involved as co-evaluators rather than passive subjects. By engaging those closest to the program in designing questions, collecting data, and interpreting findings, the approach aims to increase both the quality of the evaluation and the likelihood that findings will be understood, owned, and acted upon.
