Faith Formation classes are held primarily in Pruski Hall, with overflow in the O'Brien Center and Flanagan Administrative Center. Pruski Hall was built in 1977 and was used along with the old hall for all Faith Formation classes and parish activities. In 1991, an addition was added to the building and the building now includes a meeting room with kitchen sink, serving counter and microwave, 10 classrooms, Faith Formation library and small office. The facility was named after Fr. Ben Pruski who retired that year after many years of faithful service to St. Jerome parish. Renovations were completed by the start of Faith Formation classes in September 2014, including the addition of restrooms, updating of heating and air conditioning and water lines, work stations in classrooms, painting, replacement of windows, ceiling tiles, and floors.
