Field evaluation is a research method used to gather data and assess the impact, effectiveness, or outcomes of a program, project, or intervention in real-world settings. This type of evaluation involves collecting data in the field, such as in communities or organizations where the program is being implemented, rather than in controlled laboratory settings. Field evaluations often use a combination of quantitative and qualitative methods to measure outcomes, gather feedback from participants, and understand how the program is working in practice. This approach allows researchers to gather a more comprehensive understanding of how a program is performing and how it can be improved.
