CHICAGO — Karen Boran reads and replies to about 200 emails a day. On a recent Thursday, her Google calendar shows not a single 15-minute interval free. The first meeting of the day for the petite 56-year-old principal of John Hancock College Prep High School is with a senior afraid she won’t graduate because her attendance is below 90 percent. Second, Boran has to call in a teacher who’s fallen behind on grade entries. Then comes the mother of a boy with special needs to discuss whether Hancock–a spunky neighborhood school in a yellow brick building that towers over the small square houses surrounding it–will still be the right placement for him as a fifth-year senior. Navigating her office to welcome visitors, Boran steps over piles of books displaced in a January storm that flooded 18 of 36 classrooms, requiring some to relocate to the auditorium.As of early April, Boran and two assistant principals had collectively done 98 observations using the city’s new teacher evaluation system. Boran’s assessments take her three hours apiece, from reviewing pre-observation lesson plans to a post-evaluation conference and data entry. “And I’m fast,” she said, typing furiously on her black wireless Dell laptop. The new evaluation system, designed to keep administrators and teachers focused on instruction, is unrolling amid a historic–and historically distracting–year in the nation’s third-largest school district.
