Chana Joffe-Walt explores how white parents can shape a school — even when they aren’t there.She traces the history of I.S. 293, now the Boerum Hill School for International Studies, from the 1980s through the modern education reforms of the 2000s. In the process, Chana talks to alumni who loved their school and never questioned why it was on the edge of a white neighborhood. To them, it was just where everyone went. But she also speaks to some who watched the school change over the years and questioned whether a local community school board was secretly plotting against 293.
