Which property of classroom assessments is established by test-retest consistency?

• A. Validity
• B. Reliability
• C. Feasibility
• D. Authenticity

Answer: (B)

Test-retest consistency directly addresses reliability—the degree to which a measurement produces stable and consistent results over time. When the same group takes the same assessment on separate occasions under similar conditions, similar scores indicate that the test is dependable and not overly influenced by temporary factors or random error. That stability is what reliability is all about.

Validity, by contrast, is about whether the test actually measures what it intends to measure. Feasibility relates to practicality and ease of use in real settings. Authenticity concerns how well the task reflects real-world activities. So the property established by test-retest consistency is reliability.
