Reliablity and validity

1. face validity: the measure appears to be assessing the intended construct under study.

1.1. Materials

1.2. People

1.3. Facilities

2. criterion related: used to predict future or current performance

3. formative validity: assess how well a measure is able to provide information to help improve the program under study.

4. sampling validity : the measure covers the broad range of areas within the concept under study.

5. test/retest reliability: a measure of reliability obtained by administering the same test twice over a period of time
