Chicago says half of its public schools are underused

From The Chicago Sun-Times: Half of all Chicago public schools are underused, based on a new building utilization formula. The determination is critical for many district schools because underuse can make a school vulnerable to closure or to sharing its building with another school, such as a charter. Both options have triggered opposition in some cases. The breakdown: 336 schools underused, including 68 high schools; 77 schools overcrowded, including eight high schools; and 249 schools used “efficiently,” including 59 high schools.
