Detailed explanation-1: -Generally, if the reliability of a standardized test is above . 80, it is said to have very good reliability; if it is below . 50, it would not be considered a very reliable test. Validity refers to the accuracy of an assessment–whether or not it measures what it is supposed to measure.
Detailed explanation-2: -Concurrent validity, which is a form of criteron-related validity, is often reported. This is a numerical estimates of the extent to which a test correlates with another established test or tests.
Detailed explanation-3: -Reliability is a measure of consistency. It is the degree to which student results are the same when they take the same test on different occasions, when different scorers score the same item or task, and when different but equivalent tests are taken at the same time or at different times.
Detailed explanation-4: -A valid test will always be reliable, but the opposite isn’t true for reliability – a test may be reliable, but not valid. This is because a test could produce the same result each time, but it may not actually be measuring the thing it is designed to measure.
