The third school building was constructed in 1914 for $104,093.44. Bishop Davis dedicated the building on January 17, 1915. It was designed by Davenport architect Arthur Ebeling. During the pastorate of Msgr. Marvin Mottet in the 1990s the parish school merged with St. Alphonsus School in the west end for several years and formed John Paul Academy. Both parishes then continued to sponsor their own schools until 2004 when it was no longer feasible to operate separate schools. Once again the parishes joined together and with Holy Family School in central Davenport to form All Saints School. The former Holy Family School building was used by the school. Parish-based religious education classes were held in the Sacred Heart School building until it was torn down in the summer of 2017. A ceremony was held before the demolition.
