____________ indicates how consistent a selection device measures a criterion.

Reliability is a key concept in measurement that refers to the consistency of a selection device in measuring a particular criterion. In talent management and assessments, reliability ensures that the results obtained from the selection process are stable and repeatable over time. For example, if a selection tool is administered multiple times to the same individuals under similar conditions, a reliable tool will yield similar results each time.

When a selection instrument demonstrates high reliability, it implies that there is a low level of measurement error, which enhances the trustworthiness of the data collected. This is crucial in talent management, as decisions based on unreliable data can lead to poor hiring choices and significant impacts on organizational performance.

In contrast, while validity is concerned with whether a selection tool measures what it is intended to measure, usability pertains to how easy and effective the tool is to use. Relevancy refers to how pertinent or applicable the selection criteria are to the specific job or context. All these attributes are important, but reliability specifically addresses the consistency aspect of measurement.
