1. Validity
1.1. Criterion
1.1.1. Concurent
1.1.1.1. The degree to which a test scores correlate with scores from another similar test
1.1.2. Predictive
1.1.2.1. The degree to which the assessment will predict something in the future
1.2. Content
1.2.1. Appropriateness
1.2.1.1. The questions are appropriate for the students age and grade-level
1.2.2. Completeness
1.2.2.1. Enough questions are given to accurately assess a particular area of study
1.2.3. Complexity
1.2.3.1. How questions are asked and what is demanded of students
1.3. Construct
1.3.1. Form two groups: Those who "have it" and those who don't. The test should discriminate between the two groupsv
2. Reliability
2.1. Test-retest
2.1.1. Testing a student twice on the same knowledge to verify that the results are similar (like giving a student a test in the morning then again in the afternoon, the results should be fairly the same).
2.2. Equivalent Form
2.2.1. Reliability is establish by using similar forms that measure the same knowledge
2.3. Split-Half Form
2.3.1. After the test is administered the results are correlated by comparing the 1st half to the 2nd half
