About Us

Even more than our 110 years of academic excellence, Saint Louis Catholic School is most proud to have served parents who recognize that education is ultimately about much more than test scores. At our core we are a community of teachers, parents, and administrators, all striving to form our children with the guidance of God.

“I am so happy we chose this school for our son! Been here since kindergarten, love it more all the time!!! The community is all like family, so happy here! And my son loves it!!” – S.B., St. Louis parent.

Students Excel

On average, St. Louis students score two grades ahead on standardized tests. We believe academic achievement is typically the result of many factors. Here at St. Louis, we recognize our emphasis on parent involvement, a rigorous curriculum, and the personal engagement of our teachers as some of the key reasons our students are excelling.

Affordable Private Education

St. Louis K-8 offers tuition assistance, scholarships, and has one of the lowest tuition rates in Boulder County.  Parents, the primary educators of their children, have a right to choose the best education for their children.  St. Louis School, along with our supporting parishes and private donors, annually reduces your tuition investment and supports your decision to seek a Catholic education.  Financially, we work with all families desiring the St. Louis experience!

“Young people are a valued treasure and the future leaders of our Church. It is the responsibility of the entire Catholic community—bishops, priests, deacons, religious, and laity—to continue to strive towards the goal of making our Catholic elementary and secondary schools available, accessible, and affordable to all Catholic parents and their children, including those who are poor and middle class. All Catholics must join together in efforts to ensure that Catholic schools have administrators and teachers who are prepared to provide an exceptional educational experience for young people—one that is both truly Catholic and of the highest academic quality.”US Conference of Catholic Bishops
