San Diego is the first major city in the United States with comprehensive before and afterschool programs in every public elementary and middle school within its jurisdiction. This "6 to 6" program currently serves both elementary and middle school students in 204 public schools in the city of San Diego. With a strong public endorsement from San Diego's Mayor, "6 to 6" was able to gain support from major city offices and city leaders, local advocacy groups, the public, and the state government. This support was crucial in both the development and the sustainability of the "6 to 6" initiative. This report touches on all the details of this initiative.
