At Althoff Catholic, we partner with our students and their families to build their academic, athletic, artistic, and altruistic abilities, so that when they leave our school and enter the next stage, they know who they are. Crusaders are modern-day change agents who are not only learning, but teaching the world how to live, work, play and pray.

Academic Clubs

The Althoff Catholic Math team is a place to show off your mathematical prowess. We compete four times a year at SWIC after school.  Each competition requires three freshmen, sophomore,  junior, and senior participants.  Every participant takes the same individual math test and competes against the other kids of their grade level.  Then they break up into three teams consisting of a freshman, sophomore, junior, and senior to compete in a team test together.

Students from these schools participate as delegates to the U.N. from their respective countries.
Emphasis is placed on appropriate role playing of various delegate positions and following diplomatic/parliamentary procedures. Students are responsible for presenting prepared research on international events, especially as they would pertain to their delegation. Any Althoff Catholic student with an interest in world affairs, debate, or speech is encouraged to join.
