Choosing the right educational option for your child is one of the most important decisions you will make. Your child will spend a large part of his or her childhood at school. It’s important that your child’s school is an educational partner with like-minded values and goals, dedicated to helping your child reach his or her social, emotional, intellectual, physical, and spiritual potential.

St. John XXIII Catholic School (SJ23) is about more than academics. We are about nurturing compassionate learners who are grounded in faith and equipped with skills to be successful far beyond our doors. Students who graduate from SJ23 are known for their strong academic skills, leadership skills, and commitment to their faith.

As a parent, you may not realize all the financial pathways available to make a Catholic education affordable. To many people’s surprise, the majority of Catholic school families receive some kind of financial assistance or tuition discount. Our goal is to make Catholic education affordable and accessible to all through an individualized approach that works for you.

SJ23 offers families a number of ways to manage and reduce tuition expenses. Families can spread tuition payments over a 10- or 11-month period, “bank” money for the following year’s tuition through our SCRIP program, and take advantage of the Wisconsin Private School Tuition Tax Credit. SJ23 also offers tuition assistance to families in need.

Welcome Scholarship

The Welcome Scholarship is a one-time, 15% discount (per child), given to any first-time families attending St. John XXIII Catholic School, or families returning to St. John XXIII Catholic School after a major absence (two or more years).

FACTS Tuition Payment Program

FACTS is a national tuition management service that allows families to pay tuition and apply for tuition assistance. Families have the option of a full payment, a 10-month payment plan, or an 11-month payment plan. All families, including those who are part of the Tuition Assistance Program, must use this tuition payment program. Log in or learn more about FACTS.

Wisconsin Private School Tuition Tax Credit

In 2013, the Wisconsin Legislature approved a state budget bill (2013 Wisconsin Act 20), which established a tax deduction credit for private school tuition. Parents with dependent children in a private school are now able to receive a tax deduction for tuition.

Tuition Assistance Program

SJ23 offers tuition assistance to families who find meeting tuition expenses for their child or children a financial challenge. Families who apply for tuition assistance are able to negotiate tuition payments through this program. A dedicated fund has been established to assist families interested in giving their child or children the gift of Catholic education.
