Which of the following best defines "impact evaluation"?

Impact evaluation is best defined as an assessment that determines the direct changes attributed to a program. This type of evaluation specifically focuses on measuring the effects or outcomes that can be directly linked to an intervention or program implementation. It aims to establish a causal relationship between the program and the observed changes, which may include improvements in knowledge, behavior, or conditions within the target population.

Impact evaluations typically employ rigorous methodologies, such as randomized control trials or quasi-experimental designs, to ensure that the outcomes measured are not merely coincidental but can be confidently credited to the program's activities. By providing evidence of causation, impact evaluations are crucial for understanding the effectiveness of programs and informing future decision-making regarding resource allocation and strategy adjustments.

Other definitions, while relevant to evaluation processes, do not capture the essence of impact evaluation as clearly. For instance, assessing participant satisfaction levels focuses on subjective feedback rather than quantifiable outcomes, evaluating procedural adherence centers on the implementation of program activities rather than their effects, and frameworks for improving evaluation methods are geared towards enhancing overall evaluation practices rather than measuring direct impacts of specific interventions.
