This is a revised version of the other two Argument rubrics I have posted. This rubric still shows exactly which standards are aligned with each scale gradation, but I have taken away the substandards and included them with the actual standard. (For example, if something was 6.W.1b before, it is grouped with 6.W.1 now.) A second change is how the standards are grouped. This rubric groups them with common standards instead of by writing traits.
I moved to a Standards-Based grading classroom last year. This rubric is one of three that I am using for my district mandated pretest scores for writing abilities.
I have been using this rubric to score my pretest writing samples from my students and am amazed that I have cut my time in half from the one I used last year. I hope it works for you as well.
