A North Carolina state audit says the details and timing of a coronavirus relief grant program created last year by the General Assembly made it more difficult for low-income families to obtain payments. State Auditor Beth Wood released on Thursday a performance audit of the “Extra Credit Grant” program, which was carried out by the Department of Revenue. Families received $335 to assist with virtual schooling and child-care costs during the pandemic. The performance audit found low-income families didn’t receive payments because of the additional administrative steps during a short window of time. The grant application already has been extended to May 31.
