Validity and Reliability

1. Is used for inspecting test questions however is difficult for testing personality or aptitude trates and shows how good the test looks but does not determine the level of the test therefore content validity is more of a minimum requirement for useful test than guarenteed a good test (Kubiszyn, T. 2010).

2. Is used for the prediction of how well a examinee will test according to a skill they've learned. For example: An examinee is taught the skill of how to take a blood pressure and an examiner predicts the written test will have good test results.

3. Content Validity

4. Concurrent criterion-related validity

4.1. Is used by taking an old test and creating a new shorter version, however it must be proven to have better qualitative and quanitative results. Such as less questions resulting in shorter testing times and higher testing rank.

5. Predictive validity

6. Test Retest reliablilty

6.1. Is used by administering the same test at two different times with a measurable elapse in time. For instance giving a test on a Monday and readministering the same test the following Monday without any review in between which allows the memory to somewhat fade without complete lose of information for best test results.

7. Alternate Forms or Equivalence

7.1. Is used to administer the same test in two different forms, both resulting in like scores. For example: a student population of 20 will take a test, half will recieve test A and the other half will recieve test B. Providing that both test are considered reliable test, the scores will correlate with eachother.

8. Internal Consistency

8.1. Is used to measure the understanding of a student's skills. For example a test on blood pressures will consist of two parts, the first part will be matching and the second part will be fill in the blank, while staying consistant the technique of taking blood pressures.
