When district officials, auditors and state officials scrutinize a charter school’s finances, they often ask a basic question: Did the charter school spend more than it took in; could it cover all of its bills with its revenues? By some measures, one-third of Duval’s charter schools had trouble with that in fiscal year 2015. An analysis of the audited financial statements filed with the state indicates that at least 12 Duval charter schools spent more than they made in fiscal 2015.
