1963-1970 Mother Seton Regional High School officially opened on September 16, 1963, with only the second floor wing being functional. The first class was 115 female students. On February 1, 1964, the new convent was officially moved into with the 1964 school year consisting of two
priests and five sisters serving as faculty for 215 students. For the 1964–65 school year, the faculty was expanded to ten sisters, four priests and four lay teachers for 325 enrolled students. Sister Irene Margaret Vopelak was voted as the first principal, later hosting the first mass of the school in October 1964. Reverend
Thomas A. Boland, S.T.D., Archbishop of Newark, laid the cornerstone of the convent in 1965. This event led to a series of schools in
Central New Jersey updating security measures, including Mother Seton Regional High School. Mother Seton saw increased security measures and updated policies, with further discussion alongside the
Archdiocese of Newark on future protocols. That same year, students and faculty participated in a
nationwide protest against gun violence, honoring the 17 victims of the
Marjory Stoneman Douglas High School shooting in
Parkland, Florida. Mother Seton students attended a rally involving a video from Cardinal Tobin. After this, students proceeded outside and gathered in prayer around a statue of
Saint Elizabeth Anne Seton. This service included the Prayer of
Saint Francis of Assisi and reflections on
Psalm Prayers. This event was supported and planned by the
Archdiocese of Newark. ==Academics and Extracurriculars ==
