The percent of Illinois students who are homeless or living in poverty has grown in recent years.
In a release Wednesday, the Illinois State Board of Education says the spike in low-income students and those with limited English has led to increased costs for school districts.
But state funding for education has decreased by more than $861 million, or nearly 12 percent, since the budget year that started in July 2008.
The information comes as Gov. Pat Quinn is proposing another $400 million in cuts for elementary, secondary and higher education next year. Quinn says the proposed cut is painful but necessary because lawmakers haven't fixed the state's multibillion-dollar pension problem.
