Is It Valid? Is It Reliable?

Scenario: You are talking to Mr. Franklin about your options for informal classroom assessments as you are waiting for Manuel’s cumulative folder to arrive from his previous school site.  As described on p. 29 of your text, formal and informal assessments should be both valid and reliable.  When you mention this to Mr. Franklin he states that he had been under the impression that only standardized tests could be valid and reliable.  He then asks you to help him better understand these concepts so that he can create valid and reliable informal classroom assessments to use for all students.
