Evaluation and impact assessment are essential tools for nonprofit organizations to ensure program effectiveness, accountability, and sustainability. While evaluation provides structured analysis of program design, implementation, and outcomes, impact assessment broadens the perspective to long-term systemic effects on individuals and communities. This article examines formative, summative, process, and impact evaluation approaches, illustrating their value through case examples in literacy, vocational training, microfinance, agriculture, and health interventions. It emphasizes the role of stakeholder engagement, ethical responsibility, and methodological rigor in producing reliable evidence that informs both internal learning and external accountability. By embedding these practices into organizational culture, nonprofits can enhance strategic decision-making, sustain development outcomes, and strengthen credibility in resource-constrained environments.
