Hi Clifford: It's always difficult to experience different learning styles, abilities, intelligence, etc. I guess it's just a fact that some students will have to work harder than others to achieve the same grade. Grading rubrics help some teachers grade intangible attributes, and in doing so, some students may get a bit more credit than their more academically minded classmates. However, if it's a job skill that's being assessed, we need to assure that each and every student is proficient, regardless of the grading scale or assessment system in place. Regards, Barry
