Inter-Rater Reliability measures the extent to which raters respond the same way.

• A. Test-Retest Reliability
• B. Inter-Rater Reliability
• C. Internal Consistency Reliability
• D. Parallel Forms Reliability

Answer: (B)

Inter-rater reliability is about how consistently different raters judge or score the same thing. It captures the degree to which assessments are shared across observers, which is crucial when scores depend on human judgment rather than fixed right or wrong answers.

This makes it the best choice because the question is specifically asking about the agreement between raters. The other reliability types address different issues: test-retest reliability looks at stability of scores over time, internal consistency checks whether items on a single test measure the same construct, and parallel forms reliability compares consistency between different versions of a test. While all are important, they don’t target agreement across evaluators like inter-rater reliability does.
