Norm referenced & criterion-referenced tests

The document discusses two types of tests: norm-referenced tests (NRTs) and criterion-referenced tests (CRTs). NRTs measure global language abilities and compare student performance to others, following a normal distribution. CRTs measure specific instructional objectives and compare student performance to a set criterion or standard. The key differences between the tests are that NRTs use relative interpretation to compare students, measure general proficiency, and aim to rank students, while CRTs use absolute interpretation to measure objective-based learning, specific content mastery, and assess learning against a set standard.
Norm referenced & criterion-referenced tests
- 1. Norm-Referenced & Criterion-Referenced Tests Assigned By : Dr.Amjad Ali Arian Prepared By : Muhammad Asif
- 2. Different Types of Tests 1. Norm Referenced Tests (NRT) Measure global language abilities. Compare students’ performance to others. 2. Criterion Referenced Tests Measure specific instructional objectives Compares students’ performance to a specific criterion (Objectives or Standard)
- 3. NRT & CRT NRT 1. Administrators 2. Proficiency tests (TOEFL) 3. Percentile 4. Normal Distribution 5. Predictability of form & content CRT 1. Teachers 2. Achievement Tests 3. Percentage 4. Criterion (objectives, Standards) 5. Unpredictability of form & content
- 4. NRT & CRT Differences 1. Type of Interpretation 2. Type of Measurement 3. Purpose of Testing 4. Distribution of Scores 5. Test Structure 6. Knowledge of Questions
- 5. Type of Interpretation NRT Relative Student’s performance is compared to those of other students in percentile terms. CRT Absolute Student’s performance is compared to the percentage of material learned.
- 6. Type of Measurement NRT: Measures general language abilities or proficiency CRT: Measures specific objective- based language points
- 7. Purpose of Testing NRT: Spreading students out along a continuum of general abilities or proficiency CRT: Assessing the amount of material learned by each student
- 8. Distribution of Scores NRT: Normal distribution of scores around the mean CRT: Varies, often non-normal
- 9. Test Structure NRT: A few long subtests with a variety of item contents CRT: A series of short, well- defined subtests with similar item contents
- 10. Knowledge of Questions NRT: Students have no idea about the content in test items CRT: Students know exactly what content to expect in test items
