1. Kuder-Richardson Method

1.1. Formulas used to calculate internal consistency by calculating the values of individual halves of corresponding tests.

1.1.1. The benefit of these formulas are their accuracy, though they require more information than other methods to complete the calculations.

3. Split-Half Method

3.1. The test is broken into equivalent parts which are then calculated independently and compared for consistency.

3.1.1. The benefit of this form is the single test necessary to complete it and the removal for any external variables affecting the assessment of reliability.

4. Equivalence

4.1. The use of an equivalent forms of the same test to determine reliability of the first.

4.1.1. The benefit of this is that unlike Test/Retest Stability it eliminates the ability of students memorizing the test. It also eliminates the extended time frame necessary for retesting.

5. Test/Retest or Stability

5.1. When a test is given multiple times and the scores between the various tests are compared to find reliability.

5.1.1. The benefit of this form is its simplicity and ease of use, though the reliability of the test may be compromised because of external factors.

6. Construct Validity

6.1. This form of validity measurement is based upon the idea of expected outcomes. The test is considered valid if it coincides with expected outcomes of specific theory.

6.1.1. The benefit of this its simplicity and independence. Unlike the necessity of the Predictive model, this form does not require any additional information beyond what the individual already knows or expects.

7. Predictive Validity

7.1. This form of validity involves measuring the success of the test to "predict" future outcomes based on its results.

7.1.1. This form of validity offers the benefit of establishing probability, making it possible to measure the intangibility of future events.

8. Concurrent Criterion Related

8.1. Giving both new and "established" tests in order to determine whether the new examination is successful.

8.1.1. This offers a significant benefit by instant side by side comparison with a known quantity.

10. Content Validity

10.1. Determine whether the questions relate to the established objectives.

10.1.1. The importance of this element is a quick examination to ensure the questions ask appropriate questions for a designated learning outcome.
