Charles J. Chaput, archbishop of the Roman Catholic Archdiocese of Philadelphia, has signed documents designating 14 former parish elementary schools in low-income neighborhoods as Catholic "mission schools" operated by an independent network. The Philadelphia Inquirer says a nonprofit organization, Independence Mission Schools, will run the schools. The move is the latest development in the overhaul of education in the five-county archdiocese. The goal is to ensure that Catholic schools remain an option for families in the neediest neighborhoods. The 14 schools enroll about 4,200 students from pre-K through 8th grade. Thirteen of the schools are in Philadelphia, and one is in East Lansdowne.
