David Kirp writes that the frequent firing and turnover of coaches in the National Basketball Association is destabilizing, and the same is true in the superintendency of school districts. Of course, bad superintendents should be removed, but when the superintendent is doing a good job, they should have time to get something accomplished. The bottom line is that school districts need stability, not churn or upheaval. The same is true for schools, where stability promotes a strong culture and good working relationships. Just as coaches need time, so do principals and teachers.

Kirp is the author of “Improbable Scholars” and is a professor of public policy at Berkeley.
