You are conducting a workshop on reliability for high schoolteachers and principals. One of the topics you are covering isreliability as it pertains to commercial published tests. Youdescribe reliability evidence that test publishers typicallypresent for their tests. You emphasize that, as consumers of tests,high school teachers and principals need to pay attention to thatevidence and evaluate it. A principal, Mrs. Constantine, raises herhand to ask you a question: \"You have made a really strong case forwhy we need to look carefully at the evidence for reliability thata test publisher includes in a technical manual. But what I don'tunderstand is how high reliability needs to be for me to feelcomfortable using scores from a commercial published test to makedecisions about students.\"

How would you respond to Mrs. Constantine?

Write your one- or two-paragraph response to this question as ifyou were talking directly to Mrs. Constantine. Make certain thatyou are using teacher- and principal-friendly language as yourespond to her (i.e., no measurement terminology unless you defineterms).

In your response, identify two factors thathigh school teachers and principals need to consider when examiningthe degree of reliability presented in a technical manual for acommercial published test. Include at least twoexamples to illustrate the points you are making.
