Thanks for your responses. I have already considered most of these
issues, but reached no clear solution. I have tried educating the
evaluators. High graders remain high graders and some use the entire
scale. I'll just have to try a few methods out and see what works. I do
have external objective knowledge evaluations from standardized testing
and will see how they relate to the scores.
