Final answer:
Criterion-referenced tests are tests that measure whether students have mastered a designated body of knowledge rather than comparing them to other students in a norm group. The correct option is 3.
Step-by-step explanation:
The type of test that measures whether students have mastered a designated body of knowledge rather than how they compare with other students in a norm group is criterion-referenced tests. These tests focus on assessing a student's understanding of specific content or skills and determine whether they have achieved the learning objectives set for them.
Unlike norm-referenced tests, which compare students' scores to a norm group, criterion-referenced tests provide feedback on individual performance and determine if the student has reached a predetermined level of proficiency.
Hence, Option 3 is correct.
