In the event that the aggregate appropriations for Division I, II or III, or any other unit-driven appropriation, are insufficient to cover the total number of units certified pursuant to § 1710 of this title, the Department of Education shall transfer sufficient funding from its Growth and Upgrade General Contingency Fund and/or such other sources as the Director of the Office of Management and Budget may approve, to the school districts in order that all duly certified units are adequately funded. The Department retains the authority to require reimbursement of unit-driven funds from districts to the State that are caused by a district's inaccurate reporting of pupil enrollments.
