Evaluating impact is the process of understanding how—and how well—an organization’s work creates meaningful change. This category focuses on the methods, frameworks, and mindsets that help nonprofits, foundations, and social enterprises measure results, learn from experience, and demonstrate effectiveness to funders, partners, and communities.

Key topics include outcomes, impact measurement, logic models, theories of change, evaluation design, data collection, and learning practices. It also explores different types of evaluation—such as formative, summative, and developmental—and the balance between quantitative evidence (numbers and metrics) and qualitative insights (stories and experiences).

Strong evaluation turns information into improvement. By linking activities to measurable outcomes, organizations can refine programs, make smarter funding decisions, and strengthen accountability. Evaluating impact ensures that effort and resources translate into lasting, meaningful results for the people and causes served.
