What will be an ideal response?
• Evidence of validity based on test content is demonstrated in two ways. The first way involves performing a series of systematic steps as a test is being developed—steps to ensure that the construct being measured is clearly defined and that the items used to measure the construct are representative of the construct’s domain. There are four basic steps to the process:
o Defining the testing universe
o Developing the test specifications
o Establishing a test format
o Constructing test questions
• The second way for obtaining evidence of validity based on content involves evaluating the content of a test after the test has been developed. This method may be done by the test developer as part of the validation process or by others using the test. One statistical technique that is used is the content validity ratio.
