1. Validity
1.1. Three types of Validity
1.1.1. Criterion Related
1.1.1.1. This type of validity is important because it allows the teacher to see the degree to which performance or an assessment procedure accurately predicts a student's performance on an external criterion.
1.1.2. Content Related
1.1.2.1. This type of validity is important to learning and assessment because it allows the teacher to see the extent to which an assessment procedure adequately represents the content of the curricular aim being measured.
1.1.3. Construct Related
1.1.3.1. This type of validity is important because it allows the teacher to see the extent to which empirical evidence confirms that an inferred construct exists and that a given assessment procedure is measuring the inferred construct accurately.
2. Reliabiltiy
2.1. Three Types of Reliability
2.1.1. Stability (test-retest)
2.1.1.1. This type of reliability is important to Learning and assessment because it allows the teacher to check the consistency of the same test giving at two different times.
2.1.2. Alternate
2.1.2.1. This type of reliability is important to learning and assessment because it allows the teacher to check consistency among two or more different forms of a test
2.1.3. Internal Consistency
2.1.3.1. Internal consistency allows the teacher to keep consistency in the way an assessment instrument's items funtion
