“Los Angeles Unified School District’s Zones of Choice (ZOC) program began in 2010 as an effort to provide more high school options for a large swath of district eighth graders, combining historical catchment areas in lower-income and lower-performing neighborhoods into larger choice zones and eliminating the default feeder system from middle to high school. ZOC has proven to be an excellent model for researching the positive academic impact of choice. But as a new report published by MIT’s Blueprint Labs shows us, it is also good for examining how parental preferences are shaped.”
