John Covington has resigned as chancellor of the turnaround district for Michigan's worst-performing schools after three years.
Governor Rick Snyder created the Education Achievement Authority in 2011. It started operating in 15 Detroit schools. It was going to be expanded statewide, but expansion legislation is stalled in the Legislature.
Michigan recently terminated a contract giving the fledgling authority exclusive functions of its turnaround district.
Covington's resignation came after The Detroit News reported the authority is spending tens of thousands of dollars per month on travel.
Snyder says Covington "built a solid foundation for the work of the EAA to continue and thrive."
