Evaluation is a process used by researchers, practitioners, and educators to assess the value of a given program, project, or policy.
The primary purposes of evaluation in public health education and promotion are to:
(1) determine the effectiveness of a given intervention and/or
(2) assess and improve the quality of the intervention.
Through evaluation, we can identify our level of success in evoking desired outcomes and accomplishing desired objectives.This is accomplished by carefully formulating specific, measurable objective statements that enable evaluators to assess if the intervention influences intended indicators and/or if the correct measures were used to gage effectiveness. Determining the impact of our efforts has vast implications for the future of the intervention. For example, through evaluation we are able to identify the essential elements of a given intervention (e.g., activities, content, resources, and structure), refine content and implement strategies, and decide whether or not to invest more resources for scalability.

High-quality evaluation is contingent upon the appropriateness of the design and selected measures for the questions being posed and the population being studied. Measurement is especially critical to evaluation because it enables the evaluator to know if changes or improvements occur as a result of the intervention, and it provides testable evidence for participant progress and program success. Evaluation is a critical factor for demonstrating accountability to all stakeholders included in the intervention. More specifically, conducting an appropriate and rigorous evaluation shows that the evaluator is accountable to the audiences and communities they serve, the organization for which they work, the funding agency supporting the project, and the greater field of public health.
Evaluation serves many varied purposes in addition to providing accountability for the stakeholders. At the very core, evaluative efforts help determine if predetermined objectives related to behavior change or health improvement were achieved in the proposed health education or promotion initiative. Evaluation is also useful to improve elements surrounding program implementation (e.g., partnership development, fidelity, effectiveness, and efficiency) and can increase the level of community support for a given intervention or initiative. Further, evaluation contributes to our knowledge about the determinants of health issues as well as the best and most appropriate public health interventions to address them. This knowledge is extremely valuable to guide future research and practice. Evaluation also informs policy decisions at the organizational, local, state, national, and international level.
