The gentrification of many the country's big cities is providing a once-in-a-generation opportunity to create a large number of racially and socioeconomically integrated schools.

This article explores how the disparate cultures found in gentrifying neighborhoods clash in schools, and the pivotal role school leaders play in determining whether integration succeeds or fails, based on their ability and willingness to bridge the two worlds.
