Study says despite reforms, Chicago school improvement has been minimal

From The Chicago Tribune: A University of Chicago says that for the last two decades, Chicago's public school system has delivered only marginal improvement in student performance. The study notes that graduation rates have risen significantly, but concludes that the school system has failed to prepare elementary and middle school students for high school, putting them at long odds of entering college. Two of the men who led the school system during this time— current U.S. Secretary of Education Arne Duncan and Paul Vallas — sharply criticized the University of Chicago Consortium on School Research's study, saying it selectively chose data to paint a skewed picture of their records.
