Does NYC school district have enough schools that this kind of a curve makes sense? I've certainly been in classes that the teacher chose to do a normal-form arrangement of the number of grades, and in a lot of classes, that just didn't fit. Sometimes, such a grade-count gives a lot fewer good grades than are deserved, even on some absolute scale. More often, it gives passing grades that aren't deserved on an absolute scale. I think an "on-the-curve" grading system just doesn't reflect reality, just like a "zero-tolerance" system doesn't. They're both excuses for not recognizing individual variations.
