St. John XXIII Catholic School (SJ23) offers its students a challenging academic curriculum grounded in faith. Our students thrive in our nurturing, co-curricular environment as they obtain skills necessary to be successful, compassionate learners, innovators, educators, researchers, and leaders for the rest of their lives.

Our integrated, hands-on curriculum based on science, technology, engineering, arts, and math (STEAM) engages students of all academic levels. It promotes a deeper understanding of real-world concepts and helps students to become critical thinkers, thoughtful listeners, and effective speakers. SJ23’s co-curricular environment allows differentiated instruction and encourages creative expression as students develop socially, intellectually, emotionally, physically, and spiritually.

The success of SJ23’s rigorous academic curriculum is evident. Over the last ten years, eight of our alumni have been valedictorians or salutatorians at area high schools. Our average class size is 16 students and our instructional faculty to student ratio is 11:1.


SJ23’s Early Childhood Program is designed to grow and change with students. Our program incorporates developmentally appropriate strategies and learning opportunities for a successful social, emotional, and academic experience.

Our preschool program nurtures social and emotional growth in a structured, play environment. We work with students to develop independence, self-confidence, self-control, and group social skills according to his or her abilities and readiness. Students build upon these skills in prekindergarten while blending basic academic readiness with creative exploration.

Kindergarten students experience a more structured, hands-on learning environment that includes reading, writing, religion, science, and math. All preschool through kindergarten students have art, music, gym, and library in addition to their core curriculum. Kindergarten students also have Spanish.

Our Pre-3 Program is specifically designed to provide an environment that seamlessly transitions your child from one developmental level to the next. The structured curriculum motivates and inspires children to learn, and the nurturing, family-centered environment gives our students the individual attention needed to instill self-confidence, social skills, and a feeling of security.

St. John XXIII Catholic School offers a place where your child will be nurtured & where the values you teach at home will be reinforced.

Future City:
Future City starts with a question—how can we make the world a better place? To answer it, 6th, 7th, and 8th grade students imagine, research, design, and build cities of the future that showcase their solution to a citywide sustainability issue.
Students complete four deliverables: a 1,500-word city essay; a scale model built from recycled materials; a project plan, and a presentation to judges at Regional Competitions.

Skills gained – Students participating in Future City:

  • Apply math and science concepts to real-world issues
  • Develop writing, public speaking, problem solving, and time management skills
  • Research and propose solutions to engineering challenges
  • Discover different types of engineering and explore careers options
  • Learn how their communities work and become better citizens
  • Develop strong time management and project management skills







Dominican Challenge

  • Stem competition of around 30 middle school teams at Dominican High School
  • Our school won third place overall 2019-2020

Starting with an identical set of materials, each team will design, build, and test a small machine that will be used to complete a challenge in a tournament format. Along the way, students will utilize engineering design thinking, collect data to inform revision and upgrades, and use artistic creativity to transform raw materials into a unique, victorious product.
