This document discusses different types of tests used in education. It begins by defining norm-referenced tests, which compare students to other test-takers, and criterion-referenced tests, which measure students against a preset standard. The document then contrasts formative assessments, used during instruction to provide feedback, and summative assessments, used after instruction to evaluate learning. Finally, it discusses the benefits and characteristics of norm-referenced, criterion-referenced, formative, and summative assessments.
