What type of evaluation is provided to improve a program or person's performance early in a process?

Formative evaluation is aimed at improving a program or an individual's performance during the process rather than at the end. This type of evaluation occurs while a program is being developed or implemented and provides ongoing feedback that can inform adjustments and enhancements. By assessing progress and identifying areas that need improvement early on, formative evaluation ensures that the goals are met more effectively and efficiently.

For instance, in an educational setting, a formative evaluation might involve regular quizzes or feedback sessions that help instructors understand how students are grasping the material. This information allows for timely interventions or modifications to lesson plans.

In contrast, summative evaluation occurs at the end of a program to assess its overall effectiveness, while diagnostic evaluation typically measures knowledge or skills before a program kicks off to identify existing gaps. Normative evaluation compares the performance of individuals or programs against a standard or norm, rather than focusing on improvement throughout the process. Hence, formative evaluation stands out as the approach specifically designed for ongoing enhancement.
