Which reliability-related option lists the three types of reliability exactly as stated in the material?

• A. Scorer reliability, content reliability, and temporal reliability
• B. Inter-rater reliability, construct reliability, and face validity
• C. Scorer reliability, content reliability, and predictive reliability
• D. Temporal reliability, content reliability, and reliability coefficient

Answer: (A)

Reliability means scores are consistent across different conditions. The material describes three ways this consistency is observed: scorer reliability, which ensures that different evaluators score in the same way using the rubric; temporal reliability, which checks that test scores are stable over time if the underlying trait hasn't changed (test–retest stability); and content reliability, which looks at the internal consistency of the test items so they collectively measure the same construct. Together, these capture how consistently a measurement functions: scoring consistency, item consistency within the test, and stability over time. The other options mix in validity concepts or refer to a statistic rather than a type of reliability, so they don’t fit as the described trio.
