“A lawsuit from four Minnesota parents that claimed the state’s teachers union rules protect bad teachers and perpetuate the state’s achievement gap has been thrown out by a Ramsey County judge.
District Judge Margaret Marrinan ruled late Wednesday that the case against Gov. Mark Dayton, state Education Commissioner Brenda Cassellius, St. Paul Public Schools and three other districts did not show Minnesota’s teachers union protections were directly connected to the academic achievement gap or students of color receiving ineffective teachers.”
