Livonia Public Schools should be investigated by the state superintendent for what could be unethical practices related to charter schools.

The Michigan Association of Public School Academies said Monday it wanted Superintendent Mike Flanagan to investigate Livonia Public Schools for Hinoki International School.

MAPSA explains LPS revoked the schools charter so it could start its own Japanese-language program, which the association says steals away a successful charter school from the district.

"The superintendent last week put 11 authorizers ‘at risk of suspension’ for their supposed deficiencies," MAPSA President Dan Quisenberry said in a statement. "The names on that list were surprising, but what’s most surprising is that Livonia wasn’t on the list. It should have been No. 1."

A string of reports published by The Detroit Free Press suggests Michigan taxpayers spent close to $1 billion per year in charter schools with few state laws enacted to ensure they're operating transparently.

Flanagan explained a suspension doesn't mean the authorizers are out of business, but instead are restricted from opening new charters until deficiencies are addressed.
