There's room for debate on whether grades should reflect homework completion and timeliness, but some of the grading practices were nuts:

"...their grades are more accurately reflecting their knowledge, not whether or not they brought in a box of Kleenex for the classroom, a factor that had influenced grades at Ellis in the past."

I applaud the effort to separate knowledge grades from "life skills" grades. I can't imagine anything more useless than making a kid repeat a class or defer their graduation when they've already acquired the requisite knowledge.
