Its goals are related, but not limited to student grades and achievement. The ultimate purpose of assessment is to provide useful feedback so students can be successful learners and so teachers can teach more effectively.
Assessment can be informal or formal.
Formal assessment is generally represented by point or grade values. It can be a score of 80 out of 100 points on a math quiz, or a project graded on five rubric areas. Assessment is something that teachers learn to do almost automatically. However, it is important to consciously choose different forms of assessment, and to select assessment techniques that are appropriate to learning goals. Also, it is essential not to allow assessment to become so automatic that it goes unrecorded.
