February 2012 — The University of Chicago Consortium on Chicago
School Research found that four years after undergoing
dramatic reform
efforts, including
turnarounds, low - performing elementary
schools in Chicago closed the achievement gap in test scores by almost half in reading and two - thirds in math compared to similar
schools that did not receive intervention.
In contrast, the approach under waivers, dubbed
turnaround, was much more focused — applying only to the 5 percent of
schools identified as «priority»
schools and based on key principles outlined by the Department (see sidebar
Turnaround Principles).62 Fewer
schools were part of the
effort, but in turn, the
effort was much more intensive and required significant changes in
school operations, culture, leadership, and practice.63 The hope was that a more disruptive and ambitious strategy will yield
dramatic results: after three years, these
schools would no longer be in the bottom 5 percent, and another group of
schools could be identified to undergo
turnaround.
