What term describes the consistency of a test yielding similar scores upon repeated testing?

The term that describes the consistency of a test yielding similar scores upon repeated testing is reliability. Reliability refers to the degree to which an assessment tool produces stable and consistent results over time. In other words, if a person takes the same test multiple times, a reliable test will yield similar scores each time. This concept is crucial in psychological testing, as it ensures that the measurements obtained are dependable and meaningful.

In contrast, validity refers to whether a test measures what it intends to measure, which is a different concept focusing on the accuracy of the test rather than its consistency. Objective measurement involves the impartiality and lack of bias in the assessment process, ensuring that results are not influenced by subjective judgment. A consistency index is not a standard term used widely in psychology to describe this phenomenon; instead, it may refer to various metrics used for different purposes in research.
