Validity and Reliability
by Saul Tena

1. Construct Validity Evidence
1.1. Is a test that assesses material to determine if it matches with a theory (Kubiszyn & Borich, 2010, p. 332). Teachers can use the construct validity evidence to help them develop an effective test and to guide them on creating their teaching objectives.
2. Content Validity Evidence
2.1. Test questions are evaluated to determine if they measure the teaching objectives (Kubiszyn & Borich, 2010, p. 330). This will help teachers assess the effectiveness of their teaching objectives so they can instruct at the learning levels of their students.
3. Criterion-Related Validity Evidence
3.1. The two kinds of criterion-related validity evidence are concurrent and predictive (Kubiszyn & Borich, 2010, p. 330).
3.1.1. Concurrent criterion-related validity evidence
3.1.1.1. The results of a “new” test and “established” test are assessed to determine their correlation (Kubiszyn & Borich, 2010, p. 330). The significance of this is teachers can refer to the established test to determine the strength of the new test.
3.1.2. Predictive validity evidence
3.1.2.1. The accuracy of the test predictions is measured by testing the students at a later time on the particular area being predicted (Kubiszyn & Borich, 2010, p. 331). The test predictions if accurate can help teachers prepare learning objectives that will help their students meet their academic potential.
