According to a study by two University of Illinois-Chicago professors, the disparities between white and black students as well as white and Latino students have grown wider under Mayor Richard Daley's administration. The professors are calling for an elected school board because, they argue, Daley's appointed leaders have created high-achieving public high schools that selectively-enroll students that don't racially reflect the city on the whole, while minorities have “disproportionately experienced a string of punitive and destabilizing policies.”
