What is the difference between formative and summative evaluation in public policy?

Formative evaluation and summative evaluation are two distinct approaches used in the evaluation of public policy.

Formative evaluation focuses on the ongoing development and improvement of a policy or program. It is conducted during the implementation phase and aims to provide feedback and recommendations for adjustments or modifications to enhance its effectiveness. Formative evaluation involves continuous monitoring, data collection, and analysis to identify strengths, weaknesses, and areas for improvement. The findings from formative evaluation are used to inform decision-making and make necessary changes to the policy or program.

On the other hand, summative evaluation is conducted at the end of a policy or program's implementation to assess its overall impact and effectiveness. It aims to determine the extent to which the policy or program has achieved its intended goals and objectives. Summative evaluation involves the collection and analysis of data to provide a comprehensive assessment of the outcomes and impacts of the policy. The findings from summative evaluation are used to make judgments about the success or failure of the policy or program and to inform future decision-making.

In summary, the main difference between formative and summative evaluation in public policy lies in their timing and purpose. Formative evaluation focuses on continuous improvement during implementation, while summative evaluation assesses the overall outcomes and impacts at the end of the policy or program.
