Answer: D - When a test measures what it is designed to measure, it is said to have validity. In order to establish validity, multiple versions and test administrations are often used to provide enough correlation to ensure that the test is measuring its intended skill or knowledge level. Reliability is the consistency of a measure, meaning that if an individual takes a single test twice consecutively with no instruction, sheshould receive at or around the same score the second time as she did the first.
