While I agree with you as that is how I was trained to make rubrics, that is not the philosophy of some of the instructors that I work with. If the work is poor across the board, they wouldn't even grade it. If they get all low grades, they have still failed the assignment. Since I am the support, not the teacher at this time, this one goes their way. When using the rubric advanced grading strategy in assignments, they have to put the zero column in to make it work properly, they just don't use it.
