The correct answer is option T: true.
Explanation
There are three principles of test construction: standarization, reliability and validity.
Standarization is to try a test on a big, representative sample of people. To see the scores that are obtained in order to be able to establish the norms that future test takers will be compared against.
Reliability is the verification of the test's consistency. It means that it must be reliable and completely consistent when it is repeated through time. It must include temporary and internal consistency too.
Vailidity is the ability of a test to measure what it must measure. That is to say, to estimate the test's usefulness. It provides meaning to the test scores.
