Saint Cyril of Alexandria Catholic Elementary School - It opened in September 1929. The initial enrollment was 375. In December 2005 the archdiocese proposed closing it, but it remained open after community members, inspired by a child with cystic fibrosis who asked for the Make a Wish foundation to save his school, donated $200,000 to keep it open. This was dubbed the "Miracle at St. Cyril." In 2012 the Roman Catholic Archdiocese of Philadelphia proposed closing it again, intending to merge it into St. Andrew School of Upper Darby. However the archdiocese reversed that decision. Instead it became the Independence Mission Schools, not operated by the archdiocese. In 2012 there were 207 students.
