It talks about the different types of validity in assessment.
* Face Validity
* Content Validity
* Predictive Validity
* Concurrent Validity
* Construct Validity
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
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.
