About ACSS

Thank you for your interest in the Aberdeen Catholic School System (ACSS is often referred to as Roncalli Schools). Catholic education has served Aberdeen for nearly 125 years.  Today, our preK-12 system meets children's spiritual, intellectual, physical and emotional needs.  Throughout our three attendance centers, Roncalli Primary School (preK-2), Roncalli Elementary School (grades 3-6), and Roncalli Junior/Senior High School (grades 7-12), the ACSS achieves success through:

  • Intense faculty commitment to the individual student
  • A strong faith-based curriculum
  • Development of 21st Century Skills

Our goal at Roncalli is to instill Catholic values and promote academic excellence by nurturing mind, body and soul.
