Founded in 1853, St. John XXIII Catholic School (SJ23) fosters a spiritually rich, academically challenging, and emotionally nurturing education for students in Preschool through 8th grade.

Today, SJ23 provides a faith-based education option for almost 200 students. Together, with the support of St. John XXIII Catholic Parish, our school functions as a parochial school option for students in northern Ozaukee County.

SJ23’s rigorous, integrated, hands-on philosophy promotes differentiated instruction, encourages creative expression, promotes critical thinking, and provides students with the opportunity to obtain skills needed to be successful, compassionate learners for the future.

In partnership with parents, our administration, faculty, and staff provide a Christ-centered environment that stresses basic academic skills and competencies, as well as the arts, music, and technology. We pride ourselves in producing graduates who are well prepared to excel in any high school they choose.
