"Gov. Bruce Rauner once told some of Chicago's wealthiest and most influential civic leaders that half of the Chicago Public Schools teachers "are virtually illiterate" and half of the city's principals are "incompetent," according to emails Mayor Rahm Emanuel's administration released Thursday under a court order.
Rauner made the assertion five years ago when he was a wealthy private equity executive and an active participant in Chicago school reform. His emails were part of a discussion with affluent education reform activists connected to the Chicago Public Education Fund, including Penny Pritzker, now U.S. commerce secretary; billionaire hedge fund manager Ken Griffin; Chicago investment executive Mellody Hobson; and Helen Zell, the wife of billionaire real estate magnate Sam Zell.
"Teacher evaluation is critically important, but in a massive bureaucracy with a hostile union, where 50% of principals are managerially incompetent and half of teachers are virtually illiterate, a complete multi-dimensional evaluation system with huge subjectivity in it will be attacked, manipulated and marginalized – the status quo will prevail," Rauner wrote in a December 2011 email arguing for a strong system of teacher and principal evaluations in the district. "It's much more critical that we develop a consistent, rigorous, objective, understandable measure and reporting system for student growth upon which all further evaluation of performance will depend.""
