Revises the requirements of GS 115C-218.105 to require the local school administrative unit in which a child is enrolled in a charter school to transfer the per pupil share amount of the local current expense fund to the charter school following the receipt of monies into the fund and within 30 days of receipt of a written request from the charter school identifying the student(s) enrolled (was within 30 days of receipt of monies). Increases the sum to be transferred by 8% if the unit fails to transfer the share to the charter school within 30 days, with interest accrued at the legal rate until the total amount, including the applicable increases, is transferred to the charter school. Requires transfer of the per pupil share of any additional monies received in the local current expense fund after the initial transfer within 30 days of receipt. Prohibits delaying payment of undisputed amounts in the event of a dispute the unit and charter school disagree on the amount owed to the charter school. Applies beginning with the 2021-22 school year.
