Driving Improvement in Low-Performing Schools: Lessons From Five Years of Research on Turnaround Effects

  • Evidence of success emerged earlier in iZone schools than in ASD schools.

  • The ASD and iZones both were able to recruit high-quality teachers, but the ASD struggled to keep them

  • ASD operators faced new and unexpected challenges and tended to solve them as individual operators. Collective learning and sharing processes have not yet emerged.

  • The ASD currently faces a crisis of legitimacy and historically rooted community tensions.
