What does test validity refer to in the context of selection?

Test validity in the context of selection specifically refers to the degree to which a test accurately predicts job performance. This concept ensures that the assessment used in the selection process genuinely measures the capabilities and qualities related to successful job performance. In essence, if a test is valid, it indicates that individuals who perform well on the test are likely to succeed in the job, and those who do poorly on the test are less likely to excel.

While internal consistency of items and correct job performance measurement methods are significant facets of test design and administration, they do not directly capture the broader, more substantial aspect of validity, which is the link between the test results and actual job performance. Focusing solely on internal consistency or measurement methods does not guarantee that the assessment is predicting job performance accurately; therefore, the primary concern with validity remains the predictive accuracy regarding job success.
