What does it mean when you say that assessment is not an add on activity?

When we say that assessment is not an add-on activity, we mean that it should be an integral part of the teaching and learning process, rather than a separate or afterthought task. Effective assessment informs instruction, helps identify student needs, and drives curriculum improvement. Integrating assessment allows educators to continuously gauge understanding and adapt their approaches to foster better learning outcomes. In this way, assessment becomes a foundational component of educational practice.
