Which term describes a measure of student performance in relation to a defined standard?

The term that best describes a measure of student performance in relation to a defined standard is criterion. Criterion-referenced assessments evaluate an individual's performance against a specific set of standards or learning goals, rather than comparing it to the performance of other individuals. This type of assessment is designed to determine whether students have acquired essential skills or knowledge within a predetermined framework.

In contrast, norm-referenced assessments compare a student's performance to that of their peers, providing a relative standing rather than measuring against set criteria. Formative assessments are used primarily during the learning process to monitor student progress and inform instruction, while summative assessments typically occur at the end of an instructional period to evaluate student learning based on a wider breadth of content, and they may not directly align with specific standards as clearly as criterion-referenced measures do. Criterion-referenced assessments are pivotal in educational settings as they provide precise insights into a student's mastery of the material in relation to expected benchmarks.
