Validity/Reliability

1. Test-Retest Estimates of Reliability

1.1. This assessment is important because it helps teachers learn the student's actual knowledge.

1.2. Students should have the same result as the first test.

2. Alternate Form Estimates of Reliability

2.1. This assessment helps teachers to understand how well their test is constructed

2.2. This assessment is extremely helpful for teachers who are trying to test their students accurately.

3. Internal Consistency Estimates of Reliability

3.1. Split-Half or Odd-Even Estimates of Reliability

3.1.1. This test helps to measure one single trait.

3.2. Item-Total Correlations

3.2.1. This test measures the correlations of the entire test.

4. Content Validity Evidence

4.1. Content validity helps teachers to stay consistent with the objectives of the lesson

4.1.1. Every important when teaching a class.

5. Criterion-Related Validity

5.1. Concurrent Validity Evidence

5.1.1. Helps teachers to correlate their score with standards at the same time of measurement.

5.2. Predictive Validity Evidence

5.2.1. Correlate with standards after a period of time.

5.2.1.1. Helps teachers to stay aligned with standards

6. Construct Validity Evidence

6.1. These scores are determined to make sure that they align with other variables.

6.1.1. This helps teachers to learn if they are administering a good test or not.
