It is too early to know whether the current wave of school reforms will lead to lasting improvements in student achievement. But it is not too early to note that many of these reforms have a troubling consequence: a doubling-down on harsh, ineffective zero-tolerance discipline policies.

For that reason, advocates nationwide are embracing efforts to improve school climate. School leaders are recognizing the ineffectiveness of zero tolerance.
