Which term describes the stability of test scores across different occasions when the same test is administered?

• A. Generalizability
• B. Internal consistency reliability
• C. Test-retest reliability
• D. Content validity

Answer: (C)

This item focuses on how stable test results are when the same assessment is given on different occasions. That stability over time is called test-retest reliability. It’s usually measured by administering the test to the same people twice and looking at how well their scores on the two occasions agree, typically through a correlation. A high correlation means the test produces consistent results across time, while a low correlation suggests scores vary due to mistakes, actual change in the ability being measured, or other factors. Other concepts describe different ideas: generalizability is about applying results across settings or populations, internal consistency reliability looks at how well items on the test hang together to measure the same construct, and content validity is about how well the test covers the domain it aims to assess. Keep in mind factors like the time interval between administrations and test conditions, which can influence stability.
