Though charter schools have wildly outperformed public schools in Harlem, State Sen. Bill Perkins has attempted to block the expansion of the publicly funded, privately run charter program, and will continue his fight at his hearing challenging "the business of charter schools" in Manhattan this week. This comes as the state is being pressured to expand the program for Race to the Top funding. Local parents are pissed Perkins would put teachers unions interests before their kids. "Perkins is going against the majority of parents. He is hindering progress. Why is this nut hindering progress?" said one Harlem mom. About one in five Harlem children is enrolled in a charter school.
