If a test actually measures what it is intended to measure, then it is considered to be valid. Reliability refers to the consistency of test results, freedom of restriction of range problems refers to the variability of scores in the sample population, and internal consistency refers to the consistency of items within the test. While these are all important factors for a good test, none of them directly relate to whether the test measures what it is supposed to measure, which is the definition of validity.
