Validity:
Building valid assessments involves creating evaluation methods that accurately measure the intended knowledge or skills while ensuring consistency across multiple applications. Validity ensures that assessments truly capture what educators aim to measure, aligning with instructional content and learning objectives.
Reliability refers to the degree to which a test produces stable and consistent results when administered to the same group of test-takers multiple times. A reliable test should yield similar outcomes regardless of when or where it is administered, provided that the test-takers are comparable. This consistency is critical for the validity of test scores, as it indicates that the test items function similarly across different populations. Reliability guarantees that these measurements remain stable and consistent regardless of when the assessment is administered or who evaluates the results.
