Students from 13 states and Puerto Rico — including Michigan and Indiana in the Midwest — went to Shrub Oak this past school year. Families’ decisions to cross state borders for an education often come after they have struggled to find a place for their children. For journalists, this trend and its impact are not easy to follow. It means education reporters sometimes also have to go beyond their borders both to follow the flow of public money and to see how students are treated when they leave their communities.

And then we heard concerns that students were being mistreated at one of those schools: Shrub Oak International School in Mohegan Lake, New York. Black eyes and bruises. Insufficient staffing. Medical neglect. No kitchen.

At least 15 Illinois students were enrolled there this past school year using state and local taxpayer dollars at $573,200 each. No state outside of New York sends more students to Shrub Oak than Illinois.
