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.



St. John XXIII Catholic School is so fortunate to now be offering the Wisconsin Parental Choice Program (WPCP) to our families, parishioners, and community as a whole. The WPCP, a statewide private school voucher program, was enacted and launched in 2013, and this is our third year being able to provide this program. The program allows students whose families meet certain income qualifications the ability to attend a participating private or religious school of their choice, tuition free. The open application period for the 2020-21 school year is going on now, and due to the current circumstances, the deadline was changed from April 16, 2020 to May 14, 2020.

To set up a meeting with our principal to see if you qualify, please do so by emailing or by calling 262-284-2682.


Below is data from the School Choice State report card from the 2018-2019 school year. Our school chooses to OPT OUT of publishing our Choice student data due to the low percentage of Choice students enrolled at St. John XXIII.

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.

SJ23’s elementary and middle school curriculum is a blend of traditional textbook instruction, technology, and hands-on experiences. Language arts, writing, math, religion, social studies, science, Spanish, art, music, and gym make up our basic curriculum.

Our 5th through 8th grade middle school curriculum offers more advanced academic challenges, more leadership and service opportunities, and more co-curricular opportunities. In middle school, math is ability-based. Pre-algebra and algebra are offered to students based on readiness. Middle school students also have required service hours and have the opportunity to participate in retreats, student council, band, choir, and fine arts electives.

All of our kindergarten through 8th grade students have the opportunity to explore, invent, and create in our STEAM labs. Technology also supplements student learning. All of our prekindergarten (pre-K) through 8th grade classrooms are equipped with SMART Boards, which facilitate interactive learning. Additionally, pre-K through 4th grade students use computers and iPads to supplement group and individual instruction. Middle school students supplement instruction with laptops and Chromebooks.

Our alumni continue to excel in high school and have been accepted at colleges throughout the country. Over the last 10 years, eight alumni have been valedictorian or salutatorian at area high schools.

Our STEAM initiative offers a student-centered environment dedicated to a deeper understanding of real-world concepts and their relationship to each other. The STEAM concept explores Science and Technology, through Engineering and the Arts, all based in Mathematical elements. This hands-on, inquiry-based approach encourages our kindergarten through 8th grade students to investigate and solve real-world problems by incorporating language, fine arts, and music in addition to traditional STEM curriculum.

Steam Electives/ Projects

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.

*We are so honored to have received a $10,000 Grant from The Catholic Community Foundation for our STEM Science Initiative.

At SJ23, we support students’ individual learning needs and help them reach their highest potential by providing one-on-one and small-group student enrichment. In 5th through 8th grades, we have regularly scheduled flex time for intervention, project time, reteaching, acceleration, and enrichment. We nurture our students’ emotional and social growth weekly through individual or group counseling opportunities that focus on relationships, adolescent challenges, healthy minds and bodies, as well as other topics that promote positive social and emotional growth.

Social Emotional Coach: The Social Emotional coach’s role is to help students gain and effectively apply the knowledge and skills necessary to manage and understand their emotions, set and achieve positive goals, feel and show empathy towards others, develop and maintain positive relationships with peers, and make responsible decisions. Along with being a support to students, the Social Emotional Coach collaborates with teachers and parents to meet the needs of our students and provide information and professional development in the areas of social emotional health.

At SJ23, we believe that technology enhances traditional and hands-on teaching methods to further our students’ educational journey both inside and outside the classroom. Students use iPads and Chromebooks in the STEAM labs and classrooms to accomplish academic goals and become respectful, knowledgeable digital citizens.
