What does reliability in the context of a selection test refer to?

Reliability in the context of a selection test refers to the consistency of test results. This means that when a test is administered multiple times or under different conditions, it should yield similar results, indicating that the test measures the same underlying construct in a stable manner. High reliability ensures that the outcomes are not significantly influenced by external factors or random variations, making the test a dependable tool for evaluating candidates.

A reliable selection test contributes to the overall validity of the hiring process, as it can more accurately predict a candidate's performance on the job. Consistency in test results means that the assessment of an individual's skills, knowledge, or abilities is stable over time, providing employers with confidence in their hiring decisions. This is critical for effective strategic human resource management as it can enhance the organization's ability to select the right candidates for specific roles.
