History

Catholic education has served Aberdeen for nearly 125 years.  The first Catholic school was established inside Sacred Heart Church in 1886, and a freestanding school was built a few years later.

St. Mary's and Sacred Heart parishes each built elementary school buildings, serving grades 1 through 8, in 1912 and 1913 respectively. The Benedictine and Presentation Sisters were the primary teachers in the schools for many decades. Roncalli High School was established in 1964. Roncalli Junior High, grades 7 and 8, was established in 1969 at Sacred Heart School. In 1988, those students moved to the high school, which became Roncalli Junior/Senior High School.

In 1980, the Aberdeen Catholic School System was consolidated and Sacred Heart and St. Mary's Schools were renamed Roncalli. Kindergarten was also added to the educational program. In 1988-89 school year, the Roncalli Sonshine Patch Preschool/Daycare Program was created. In 2002-2004, ACSS demolished its elementary buildings and built Roncalli Primary School (preK-2) and Roncalli Elementary School (3-6).

Roncalli is Pope John XXIII's family name. Elected Pope on October 28, 1958, he was to be only an "interim" pope; however, he captured the entire world's imagination and changed millions' hearts in a short space of time. Pope John XXIII changed modern Christianity by summoning the Second Vatican Council to deal specifically with the question of Christian unity. Under his leadership, the church made many sweeping changes to help meet modern times' challenges. In 1964, the name selection committee felt that the new high school, Roncalli, should be dedicated to the same objective as Pope John XXIII, by assisting the Catholic students of Aberdeen in meeting the challenge of the modern time... educationally, socially, and spiritually.
