Your evaluation criteria (or standards for mastery) must be explicit and specific so that the data you collect from an assessment is as useful to you as possible.
Here is an example of unspecific (and therefore insufficient) evaluation criteria:
- Students must list 3 similarities and 6 differences in their Venn Diagram
- 6 of 9 responses must be correct
Now, here is an example of sufficient evaluation criteria:
- Students must list 3 similarities and 6 differences
- At least 6 of the nine responses must be correct
- There must be at least 2 correct in each of the 3 sections of the Venn Diagram so as to indicate that the student met the objective of identifying similarities and differences
