Our research revealed a pattern of school choice results that range from neutral (no significant differences between Choice and MPS) to positive (clear benefit to Choice). Although we have examined virtually every possible way that school choice could systematically affect people, schools, and neighborhoods in Milwaukee, we have found no evidence of any harmful effects of choice.
