This is a story about how the hunt for a good public school can move a New York City family out of their home. After the birth of their first son, Jeanne Kempton and Damien Corr followed a trajectory familiar to many New York families, buying in an area — Cobble Hill, Brooklyn — with excellent public schools and biding their time in a two-bedroom condo until their second son was also safely ensconced in District 15.
