The following men began their service as priests in Pittsburgh before being appointed bishops elsewhere:  The Diocese of Pittsburgh's elementary and secondary schools educate approximately 17,000 students and employ nearly 1,500 teachers, making its school system the fourth largest in Pennsylvania. As of March 2018, the Catholic school system in the diocese operates 69 elementary, pre-K and special schools. The diocese says that enrollment in its school system has fallen by 50 percent since 2000. The diocese is in the process of reorganizing its grade schools. Between 2005 and 2010, sixteen elementary schools were closed, with more mergers and consolidations planned. In March 2018, the diocese announced the merger of two elementary schools and the closure of one school. Saint Rosalia Academy in Greenfield was closed at the end of the academic year. The closure was endorsed by the Pittsburgh-East Regional Catholic Elementary Schools Advisory Board. North American Martyrs School and the Saint Bernadette School, both K-8 institutions in Monroeville, will merge at the start of the 2018-2019 school year. Bishop Zubik has said the new school would be known as the Divine Mercy Academy. In January 2020, the Pittsburgh-East Regional Catholic Elementary Schools (PERCES) announced the closure of East Catholic School in Forest Hills and Saint Maria Goretti in Bloomfield. The organization cited significant enrollment declines and growing debt as reasons for the closures. Their programs will be shutdown at the end of the 2019-2020 school year. In addition to the closures, PERCES announced that Saint Anne School in Castle Shannon, Saint Bernard School in Mount Lebanon, Our Lady of Grace School in Scott Township, and Saint Thomas More School in Bethel Park will merge to form one unified school program, starting in the 2020-2021 school year. The program will have two preschool through eighth grade sites: one at Saint Thomas More and one at Saint Bernard. Three Catholic colleges and universities operate within the diocese: Duquesne University, Carlow University, and La Roche College. While affiliated with the Catholic Church, they only receive indirect support from the diocese, such as tuition support for students who previously studied at Catholic grade schools or high schools. Seminarians studying for the priesthood in the Diocese of Pittsburgh complete pre-theological studies at Saint Paul Seminary in the East Carnegie neighborhood of the city of Pittsburgh. Every year the diocese holds the Medallion Ball, a debutante ball, that honors young women who perform at least 100 hours of eligible volunteer work.
