This chapter had a section that talked about self-tests to see if my assessments are "appropriate". To check whether my criteria and rubrics are appropriate I'm to consider the following questions: "Could the proposed criteria be met but the performer still not demonstrate deep understanding? Could the proposed criteria not be met but the performer nonetheless still show understanding?" (p. 188) If the answer to any of these questions is yes, then my criteria of not good enough yet.
So my question is what if I created an assessment where the answer would be yes for some students and no for others? What I'm trying to say is, what if my criteria worked for most of my students, but not all? What if I come across a student that wants to memorize the procedures and refuses to "think"?

I don't know if I made myself clear, but I'm just writing all these questions that come to mind :)
