What is the difference between assessment and evaluation?

Understanding the distinction between assessment and evaluation is crucial in education. Assessment is a process of gathering information about student learning and performance over time. It is often formative, diagnostic, and ongoing, aiming to monitor progress, identify areas for improvement, and provide feedback to guide further learning. Examples include quizzes, observations, and informal checks for understanding. The goal of assessment is to inform and improve. In contrast, evaluation is a judgment or a determination of worth or value, typically made at a specific point in time. It is often summative, involving the interpretation of assessment data to make decisions, assign grades, or determine mastery. For instance, a final exam or a project grade is an evaluation. While assessment provides the data, evaluation uses that data to make a conclusive statement about achievement or effectiveness. They are distinct but interconnected components of the educational measurement landscape.
