What is a norm based assessment?

Norm-based assessment is a method of evaluating an individual's performance by comparing it to the performance of a defined group, often referred to as a normative group. This approach uses statistical measures, such as mean and standard deviation, to interpret the results, allowing educators or psychologists to determine where an individual stands relative to peers. It is commonly used in educational testing and psychological assessments to identify strengths, weaknesses, and areas for improvement. By analyzing how an individual's scores align with those of the normative group, practitioners can make informed decisions regarding interventions or support.
