Despite the challenges, some districts have taken the decisive step of closing low-performing schools. This paper, written by Lucy Steiner for the Center on Innovation and Improvement, discusses the lessons district officials in four urban districts learned about the school closure process. Recommendations include the need to: 1) consider school closure in the context of a larger reform effort; 2) develop a supply of higher-performing school options; 3) clearly explain to the public how current students will benefit; 4) provide support to families and students during the transition; and 5) provide staff members with clear information about next steps.
