Chapter 3 of our textbook discusses several important aspects of standardized testing.  One idea is the importance of reliability and validity in standardized tests.  For this post, watch the following videos on test validity and reliability.

1. Introduction to Test Validity
2. Reliability

Then, imagine that your center or school is looking for an assessment instrument to measure reading ability.  The selection has been narrowed to two possibilities: Test A shows measures of strong validity, but there is no information about its reliability; Test B includes measures of strong reliability, but there is no information about its validity.  Which test would you recommend?  Be sure to include at least three specific reasons as to why you chose the test you did.
