Charter schools sue Durham (N.C.) district over funding

From The Raleigh News & Observer: Five charter schools are suing the Durham (N.C.) school district for more than $1.2 million they say the district owes them from the past five years. The charters contend that the district is using different formulas to determine how much money they receive and how much the district spends, per student. Durham bases its per student funding on enrollment at the beginning of the year but is paying charter schools based on their monthly numbers, the suit asserts.
