face validity

face validity
【正确答案】：A test is valid if it measures what it is supposed to measure, or if it does what it is supposed to do. There are three kinds of validity vital for language testing, one of which is face validity. Face validity is concerned with what teachers and students think of the test. One way to judge face validity is to ask the teachers and students concerned for their opinions, either formally by means of a questionnaire or informally by discussion in class or staff rooms.
