Norm-referenced evaluations measure an individual's performance in relation to a known group, using items of average difficulty to create a diverse score distribution. These tests allow for judgments based on relative performance, enabling selection and grouping of students. Both norm-referenced and criterion-referenced tests share similarities in their achievement domain specification, sample selection, item construction, and assessment quality criteria.
