Leaders of Detroit’s main school district spent much of this year fighting to keep schools open.

At the same, however, the district was preparing to shut a school down.

That school, the Ross-Hill Academy charter school, quietly closed forever last month after serving Detroit children on the east side for 19 years.

The kindergarten to eighth-grade school had taken on too much debt, district officials said, and was in danger of not having enough money to stay open through the next school year.

“As a district, we always try to do what’s right for children and, in this case, it would have been irresponsible to allow a school to stay open that had really any chance of potentially leaving parents stranded,” said Kisha Verdusco, the district’s director of charter schools. “If we had allowed them to go into another school year, you’re taking a gamble that they’re not going to have enough students to be viable.”

Ross-Hill, which enrolled just 110 students last year, had been one of 13 charter schools overseen by the Detroit district.

Under new superintendent Nikolai Vitti, the district has been rethinking its approach to charter schools. That could lead to additional charter school closings in coming years. But Vitti’s predecessors have been overseeing charter schools for more than two decades. Unlike the 100-plus traditional schools that are managed directly by the district, charter schools have independent managers who report to independent school boards.

In its role as authorizer, the district keeps tabs on charter schools, making sure they’re academically and financially viable. The district’s charter school office determined in March that Ross-Hill was not on stable footing.

“Enrollment had been declining for some years,” Verdusco said. “We track schools’ quarterly financial performance so we were really keeping a close eye on what was going on.”

Unless the school dramatically found a way to raise enrollment, which would bring in more state dollars, officials did not believe the school could survive, Verdusco said.

A woman who answered the phone at the school said its principal and management company were not available to comment. The school closed last month.

Ross-Hill has had a mixed academic track record over the years but its low scores last year put the school near the bottom of state rankings. It ranked in the 4th percentile, behind the vast majority of Michigan schools.

The school was hardly alone at the bottom of state rankings. Of 162 Detroit schools that were ranked in 2016, 69 were in the bottom five percent of Michigan schools.

That’s part of why state officials announced plans to shutter 24 Detroit schools that had been in the bottom five percent for three years in a row.

That effort triggered loud community protests and lawsuits by school boards that led the state to back down. Instead of closing schools, state officials brokered partnership agreements designed to help them improve.

As a result, the only Detroit schools being shut down this year are charter schools. (One district school, Durfee Elementary-Middle School, is moving into the adjacent Central High School).

Ross-Hill is among at least seven charter schools in or near Detroit that closed forever last month.

Central Michigan University, the state’s largest charter school authorizer, declined to renew the charters of the Woodward Academy and the Michigan Technical Academy in Detroit; the Starr Detroit Academy in Harper Woods, the Taylor International Academy in Southfield and the Academy of International Studies in Hamtramck. Also closing is the Blanche Kelso Bruce Academy, a strict discipline academy that served children who had been expelled by other schools or referred by the juvenile courts. It had been overseen by the Wayne County intermediate school district.

At some of those schools, parents complained that they weren’t notified in a timely manner. At the Woodward Academy, some parents found out about the closing from a Chalkbeat reporter. At Taylor International, the school abruptly shut its doors two weeks before the end of the school year when it ran out of money and its management company left.

Verdusco said she took steps to make sure the closing of Ross-Hill went smoothly. A parent meeting was held in April for parents to voice their concerns about the closing and an enrollment fair helped families find other schools options.

Some parents chose district schools. Others chose charters, she said.

Converting Ross-Hill to a district school was not an option because the charter school was in a building owned by a church, Verdusco said.
