St. John XXIII Catholic School (SJ23) provides a foundation of Catholic values and academic excellence for its students in preschool through 8th grade. Our faculty and staff is dedicated to building a strong academic, social, emotional, and spiritual foundation for our students. SJ23’s teachers actively engage and inspire diverse learning styles so every student reaches his or her potential while at SJ23 and beyond. We are growing as saints together through service, excellence, discipleship, and community.

SJ23 offers many co-curricular and student life enrichment programs in addition to its outstanding core curriculum, including:

  • Academic Challenge Competitions

SJ23 students are creative and enjoy many opportunities to show their fine arts skills. Art, music, and choir are offered to all students as part of the regular curriculum.

At the middle school level, students have additional choices of beginner band, concert band, and jazz band. They also have elective fine arts selections, including mallet madness/world music, makerspace, theater/drama performance, and music technology editing/production. SJ23 students absolutely love these creative, hands-on opportunities.

Participation in Scouts is available to all SJ23 students. Clubs evolve and change based on student interests and parent enthusiasm. Currently, we offer Lego Club and Spanish Club.

Student council members genuinely want a leadership role in our school and are committed to serving our school, parish, and local communities. These students are dynamic, responsible, enthusiastic, and committed to making a difference through service leadership.

A significant part of SJ23 student and family life is living our faith. We focus on the gifts of each student and challenge him or her to become a compassionate individual committed to justice, compassion, and service. At SJ23, we believe in inspiring one another to lead and serve through our actions every day in the classroom and our community.

At SJ23, our students contribute to the Mass as liturgical ministers and participate in peace prayer services and retreats. SJ23 faculty provides recognition of our students through the “Caught Being Christian” program and public servant recognition. We involve our students in our ministry of serving the community. We have recently served the following community organizations:

  • American Heart Association: Jump Rope for Heart
  • Cards and Poinsettia Delivery for Parish Homebound
  • Catholic Relief Services: Rice Bowl
  • Columban Fathers: Missionary Society of St. Columban
  • Feed My Starving Children
  • Harbor Club Visits
  • MACC Fund
  • Port Washington Senior Center
  • Salvatorian Mission Warehouse
  • Soles for Catholic Education
  • St. Ben’s Meal Program
  • St. Peter’s Food Pantry Food and Clothing Drives
  • Wisconsin Humane Society

Our mission at SJ23 is not only to foster the academic success of our students, but also to nurture lifelong Catholic values that build strong character and meaningful relationship with God. In partnership with our families and the Catholic Church, we strive to guide each child as he or she grows and matures in knowledge and faith.

Students develop a deep appreciation of the liturgy through active weekly Mass participation and through daily religious instruction, reflection, and prayer. SJ23 students further their spiritual journey by preparing for and receiving the sacrament of first holy Communion and reconciliation. Outside the classroom, students focus on individual and communal spiritual growth through retreats and service.
