The document discusses the concept of validity in testing, which refers to how accurately a test measures what it intends to measure. It outlines various types of validity, including face, content, concurrent, predictive, and construct validity, along with factors affecting test validity. The document emphasizes the importance of criteria and subjectivity in assessing the effectiveness and appropriateness of tests.

2. VALIDITY
• the degree to which a test actually
measures what it tries to measure.

5. Some Factors that Affect the Validity
of a Test
1. Reading Vocabulary and Sentence Structure
2. Pattern of the answers
3. Arrangement of the test items
4. Poorly Constructed test items
5. Ambiguity

6. Types of Validity

7. FACE VALIDITY
the extent to which a test is subjectively
viewed as covering the concept it tries to
measure

8. In judging face validity...
 3 knowledgeable persons
 appropriateness
 suitability
 mechanics

9. " looks like " it
is going to
measure what
it is supposed
to measure

10. Content Validity
the extent to which the content or topic of the
test is truly representative of the course

11. Concurrent Validity
 is the degree to which the test agrees or correlates with a
criterion set up as an acceptable measure
 the criterion is always available at the time of testing
 it is applicable to test employed for the diagnosis of
existing status rather than for the prediction of further
outcome

12. Predictive Validity
o is determined by showing how well predictions made from the test
are confirmed by evidence gathered at home subsequent time.
o the criterion measure against this type of validity is important
because the outcome of the subject is predicted

13. Construct Validity
 is the extent to which the test measures
a theoretical trait. This involves such test
as those of understanding, appreciation,
and interpretation of data. Examples are
intelligence and mechanical aptitude
tests.
