The surprise resignation of Minneapolis Superintendent Bernadeia Johnson has placed the district squarely among a growing number of troubled urban school systems that have lost their top leaders recently.
"We are going through a period at the moment where we are seeing substantial turnover," said Michael Casserly, the executive director at the Council of Great City Schools. "It's not clear if it is episodic or if there is a larger trend beginning to emerge."
Los Angeles; Seattle; Albuquerque, N.M., and now Minneapolis are just a few of the districts that have lost their top executive this year.
Education experts say the departures are part of a larger national trend where superintendents are getting increasingly bogged down by complex political landscapes and well-oiled resistance inside and outside of the district.
Former Minneapolis Mayor R.T. Rybak defended Johnson on his Facebook page Tuesday, saying that when he was mayor he always said he had the "second toughest job in town."
"People care a lot about potholes, but they care a whole lot more about their kids," said Rybak, now the executive director of Generation Next, which is working to improve student achievement.
Minneapolis has churned through 14 interim and permanent superintendents in the past 30 years. The average tenure for superintendents nationally is just 3.2 years, according to a 2014 study conducted by Casserly's organization.
"I don't know of many other places, other than the National Football League or police chiefs, where the turnover is as high as it is in urban school systems," Casserly said.
