Question

Quizplus · Accepted Answer

Norm-referenced tests compare a test-taker's performance to that of a norm group, while criterion-referenced tests measure a test-taker's performance against a fixed set of criteria or standards. While both types of tests require the specification of the achievement domain (A), are judged by validity and reliability (C), and are useful in educational measurement (D), criterion-referenced tests do not necessarily require items to cover a broad range of difficulty (B). Criterion-referenced tests focus on whether each test-taker has achieved specific skills or knowledge, regardless of how others perform, making the range of item difficulty less relevant compared to norm-referenced tests, which require a broad range of difficulty to accurately rank test-takers against each other.
