FERPA - This is not legal; also poorly conceived (Score 4, Informative)

It is not legal to publicly display students' grades. It's part of the Family Educational Rights and Privacy Act (FERPA). A teacher could lose his license for sharing a student's grade with others. It seems that 'achievement level' should fall under that as well. This shows a poor understanding of behavior. Those students who might struggle will now be more motivated to act out or fail outright (rather than seem to struggle and fail).
