The Obama administration is considering a major last-minute policy shift that could force hundreds of school districts to cut spending at well-financed elementary and secondary schools and move nearly $1 billion dollars to schools with large numbers of low-income students.
The regulation would apply only to school districts that have both low-income schools that get Title I federal funds and higher-income schools that are not eligible for the money.
In announcing the proposal in August, King called it "an important step forward to advancing resource equity across the country." King also urged districts and states to comply with the regulation "by providing additional funds for education focused on high-needs schools, not by shifting dollars around or forcing transfers of teachers or other personnel."
"If this were to be finalized, it would be a huge deal because it's saying how local and state money inside school districts is to be distributed across schools," said Nora Gordon, a school-finance expert at Georgetown University.
Lamar Alexander, chairman of the Senate education committee and a former secretary of education, has vowed to block the regulation -- a move that would require a majority vote in both houses of Congress and the President's signature.
Adopting the regulation before Friday at noon would bind the incoming Trump administration unless Congress overturns it.
The National School Boards Association called the regulation "unnecessary" and "unwarranted federal overreach" that would constrain school districts.
