has increased. If growth trends continue, Detroit's charter schools enrollment will outpace the Detroit Public Schools by 2015. Officials at the Detroit Public Schools and Detroit Federation of Teachers oppose the expansion of charter schools. The Thompson Educational Foundation financed a new University Preparatory Academy High School, and provides yearly scholarships on condition of meeting student performance goals. Follow up studies of the University Prep Academy class of 2007 shows that at least 90% went on to college, 83% of those who attended a four-year university re-enrolled for a second year, and 57% of those who attended a two-year college re-enrolled for a second year, beating national re-enrollment averages. However, these scores are below high performing DHS schools with selective enrollment such as Bates Academy, Burton International and Renaissance High School. There have been significant calls for the Detroit Public Schools to cooperate more with charters, including renting unused schools to charters. In May 2008, the DPS board renewed contracts with six charter schools for two years. DPS leases some closed school buildings to charter school operators. Leadership Superintendent In March 2007, the DPS board removed Superintendent William Coleman and replaced him with Connie Calloway. Lamont Satchel was named as Interim Superintendent. Coleman was still paid for the remainder of his contract. Connie Calloway was removed after 18 months after accusations by the school board that she was behaving unprofessionally and exercising poor judgment. She later won a lawsuit for wrongful termination, and termination without due process in retaliation for filing a whistle-blowing lawsuit when the treasurer reported ongoing misappropriation of more than 77 million dollars per year in funds intended for the children of Detroit. Past superintendents include Warren E. Bow, Kenneth S. Burnley, Charles Ernest Chadsey, Duane Doty, and John M. B. Sill. Emergency financial manager The District was under a state-appointed Emergency Manager from 2009 to 2017. The Emergency Manager has powers to make unilateral changes. All financial decisions have been made by the Emergency Manager. From 2009 to 2011, DPS finances were managed by Robert Bobb who was appointed by former Governor Jennifer Granholm, and from 2011 to January 2015, by Roy Roberts who was appointed by Governor Rick Snyder. In January 2015, Governor Snyder appointed Darnell Earley as Roberts' successor. Earley resigned in February 2016 in the wake of criticism of his decision, when he was Emergency Manager over Flint, Michigan, to switch that city's
