Yes, I saw that there was actually a Supreme Court case on peer-graded papers--interesting. So apparently you can completely circumvent this if you just have the kids grade everything. (I very much doubt this test was student-graded.)

I'd like to see something in plain English from a state educational authority saying that student grades on all assignments must be kept confidential. I suppose this may not exist because we all know that students do share their grades (not the same as a teacher sharing them, but I wonder how they handle that legally).

I can easily think of another instance where this school violated FERPA, if this is the law. I now understand some odd teacher behavior in that instance.
