What is

Evaluation

Evaluation is the systematic process of collecting, analyzing, and interpreting information to assess how well a program, policy, or organization is achieving its goals. It helps determine effectiveness, efficiency, relevance, and sustainability of activities. In the nonprofit and social impact sectors, evaluation is both a learning tool and an accountability mechanism—informing decisions, improving design, and demonstrating results to funders, participants, and the public. Evaluation differs from routine monitoring by focusing on why and how change happens, not just what was done. It blends quantitative data (numbers, metrics) and qualitative data (stories, interviews, observations) to provide a full picture of performance and impact.

Why It Matters

Evaluation ensures that resources are used wisely and that programs are making a meaningful difference. It enables organizations to learn from experience, replicate what works, and discontinue what doesn’t. Funders, policymakers, and donors increasingly expect evidence of impact, making evaluation a vital part of strategic decision-making and continuous improvement.

Types of Evaluation

Formative Evaluation: Conducted during the development or early implementation of a program to refine and improve its design and delivery.
Summative Evaluation: Conducted after a program is completed to assess overall effectiveness and outcomes.
Process (or Implementation) Evaluation: Examines how a program is delivered—its activities, participants, and operations—to determine whether it’s being implemented as intended.
Outcome Evaluation: Focuses on the short- and medium-term results or changes that occur because of a program.
Impact Evaluation: Looks at long-term, broader changes and seeks to determine whether outcomes can be attributed directly to the program.
Developmental Evaluation: Supports programs operating in complex, evolving environments by providing real-time feedback to guide adaptation and innovation.

Approaches to Evaluation

Participatory Evaluation: Involves program participants, staff, and community members directly in designing and conducting the evaluation, ensuring local relevance and ownership.
Utilization-Focused Evaluation: Designed with the primary goal of producing findings that will actually be used by decision-makers.
Theory-Based Evaluation: Assesses how and why change is expected to occur, often guided by a Theory of Change or Logic Model.
Empowerment Evaluation: Builds evaluation capacity within organizations by teaching staff to evaluate and improve their own programs.
Mixed-Methods Evaluation: Combines quantitative and qualitative data to balance measurable outcomes with context and personal experience.
Experimental and Quasi-Experimental Evaluation: Uses comparison or control groups to determine causality (e.g., through randomized controlled trials or matched samples).
