The groundbreaking move follows negotiations with the federal government, which sent out a letter to school systems warning that disciplinary patterns with “disparate impact” were under suspicion. There is of course a reformist cast for rethinking some harsh aspects of school discipline systems, zero tolerance policies being one, but not the only, example. Such reforms might well have the effect of narrowing disproportionately high rates of discipline for students in some minority groups. But the Minneapolis system’s move (apparently encouraged by Washington) to consider race explicitly in the suspension process, with minority kids getting an additional layer of review, raises the likelihood of a challenge under the Constitution’s equal protection clause, as does the setting of an enforceable compliance objective of achieving identical suspension rates from one demographic group to the next independent of whether misconduct rates are identical.
