Question

Quizplus · Accepted Answer

Stability or consistency is an indicator of reliability. A performance standard that consistently produces similar results over time is considered reliable. Option A, free from contamination, refers to the absence of extraneous factors that may affect the results, and option B, relevant, refers to the suitability of the standard to the task or skill being evaluated. Option D, valid, refers to the accuracy of the standard in measuring the intended construct or attribute. While stability is important for validity, it is not the same as validity.
