What is being measured if the HR department re-administers a job interest test to the same people a week later?

• A. Internal consistency
• B. Inter-rater reliability
• C. Test-retest reliability
• D. Split-half reliability

Answer: (C)

When the HR department re-administers a job interest test to the same individuals one week later, they are assessing test-retest reliability. This form of reliability evaluates the stability and consistency of a test over time. By administering the same test to the same group after a specific interval, one can determine whether the results are similar, indicating that the test effectively measures the same construct under similar conditions after the time gap. This approach is essential for ensuring that the test accurately assesses job interests rather than being influenced by external factors or temporary states of the respondents. If the scores are consistent across the two administrations, it suggests that the test produces reliable outcomes regardless of when it is administered, thus validating its effectiveness as a measurement tool.
