1. Reliability refers to the extent to which assessments are consistent.

1.3. Phone Calls

1.3.1. Call 1

1.3.2. Call 2

1.4. Meetings

1.4.1. Meeting 1

2. Another measure of reliability is the internal consistency of the items.

4. Since teachers, parents, and school districts make decisions about students based on assessments (such as grades, promotions, and graduation), the validity inferred from the assessments is essential -- even more crucial than the reliability
