Quizplus · Accepted Answer

Both reliability and validity are necessary for a selection method to accurately predict success. Reliability refers to the consistency of the results produced by the selection method, while validity refers to the degree to which the selection method measures what it is intended to measure. Without reliability, the results of the selection method will be inconsistent and unpredictable. Without validity, the selection method may not accurately measure the qualities or skills necessary for success in the job or task.
