A new analysis (PDF) by the Madison school district shows that the budget submitted by the Urban League of Greater Madison for a pair of sex-segregated charter schools could potentially cost the district an additional $13 million over the schools’ first five years.
The new numbers came as a shock to Urban League president Kaleem Caire, who says that Madison Prep may pull out of a tentative agreement with Madison Teachers, Inc., that would require Madison Prep to hire mostly union staff.
“It’s become clear to us that the most reasonable path to ensure the success of these kids is as a non-instrumentality,” says Caire. “Others on our board want to look at a couple of other options, so we’re looking at those before we make that final determination.”
One of those options would be to scale back the program, including the proposed longer school days and extended school year.
