Understanding Key Test Concepts: Validity, Objectivity, and Standardization
When creating or taking tests, it’s important to understand certain key concepts:
1. Validity
-
Definition: Validity checks whether a test measures exactly what it is intended to measure.
-
Example: A math test meant to assess multiplication skills should focus on multiplication questions, not addition.
2. Objectivity
-
Definition: Objectivity ensures that scoring does not depend on the person grading the test.
-
Example: Multiple-choice tests are highly objective because answers are clearly right or wrong. Essays require a rubric to increase objectivity.
3. Standardization
-
Definition: Standardization means that a test is administered and scored in the same way for everyone.
-
Example: Giving one student 1 hour in a quiet room and another 30 minutes in a noisy room is not standardized. Standardization ensures fairness.
