Junior Boarding School

4 boys and a nun

St. Catherine’s Academy

Founded in 1889, SCA is a Catholic school with a military tradition. We provide a junior boarding school experience unlike any other.

Focused on Junior Boarders (4th – 8th Grade)

As the only California boarding school to accommodate students in 4th - 8th grade, SCA has a special focus on the needs of junior boarding students. While attending a boarding school will increase the maturity and responsibility of your son, students in this age group need extra support to live away from home. Our unique boarding program includes 24-hour supervision, daily study hall, and lots of organized activities.

5-Day Boarding Option

In addition to a typical 7-day boarding program, SCA offers a unique 5-day boarding program for families who live within driving distance. As a 5-day boarder, your son will benefit from the structure and support of our junior boarding program during the school week while returning home for quality time on weekends.

International Community

As an international boarding school, St. Catherine’s Academy draws boys from all over the world who come to our school to learn English and experience life in America. Within our close-knit residential community, students develop an understanding for other cultures and learn to relate to one another.

Outings and Activities

California boarding schools provide many opportunities for weekend outings and campus activities to keep students occupied outside of school and study time. Our full-time junior boarding students enjoy field trips to a variety of southern California destinations, including Disneyland, Universal Studios, state beaches and parks, sporting events, and more.

Superior Academic Program

As an all-boys school, St. Catherine’s Academy offers a superior academic program focused on the unique learning needs of boys. Your son will also benefit from our small classes, individualized instruction, and state-of-the-art technology. Boarding students receive additional academic support during daily study hall. Your son will choose from a variety of enrichment and extracurricular activities, such as music, athletics, and technology.

A Catholic School with a Military Tradition
