Representation Validity

Representation Validity

Face validity is the extent to which a test is subjectively viewed as covering the concept it purports to measure. It refers to the transparency or relevance of a test as they appear to test participants. In other words, a test can be said to have face validity if it "looks like" it is going to measure what it is supposed to measure. For instance, if you prepare a test to measure whether students can perform multiplication, and the people you show it to all agree that it looks like a good test of multiplication ability, you have shown the face validity of your test.

Some people use the term face validity only to refer to the validity of observers who are not expert in testing methodologies. For instance, if you have a test that is designed to measure whether children are good spellers, and you ask their parents whether the test is a good test, you are studying the face validity of the test. If you ask an expert in testing spelling, some people would argue that you are not testing face validity. This distinction seems too careful for most applications . Generally face validity means that the test "looks like" it will work, as opposed to "has been shown to work".
