What encompasses tasks required by the job to validate a selection test?

Content validity encompasses the tasks required by the job to validate a selection test, as it focuses on whether the test items represent the specific knowledge, skills, and abilities that are necessary for performing the job. This type of validity ensures that the test measures what it is intended to measure, directly aligning the content of the selection instrument with the relevant job tasks.

In the context of selection tests, content validity is assessed by evaluating the relevance and adequacy of test items in relation to the job's critical dimensions. A well-established content validity gives confidence that candidates who perform well on the test are likely to perform well on the job because the test accurately reflects the job’s requirements.

The other forms of validity mentioned serve different purposes. Criterion-related validity compares the test to a relevant criterion, such as job performance, rather than assessing the relevance of the test content itself. Construct validity focuses on the theoretical construct that the test is supposed to measure. Job analysis validity is not a standardized term in validity classification but rather relates to the systematic process of defining job roles, responsibilities, and requirements, which supports the basis for establishing content validity.
