Shaping Young Minds

Emphasis is placed on the students’ preparedness for an ever demanding and diverse world.

The St. Thomas community, which includes students, parents, faculty, staff and alumni, nourishes the faith of all its members. Together, and as individuals, members of the community share the responsibility of actively bearing Christ’s message to the society at large. Promotion of social justice and service to those in need stand at the core of this mission.

Mathematics Department

The goal of the Math Department is to provide a curriculum that enables each student to challenge himself to achieve to his fullest potential – in Math and outside it, in high school and beyond. We help prepare students for the highest levels of math and science courses at St. Thomas, which require mathematical skills, and for their mathematics courses at the university level as well. For many highly motivated students, this includes the challenge to earn college credit through the Advanced Placement Program.

We endeavor to help students appreciate the beauty of mathematics, the richness of its language, the elegance of its logic, the power of its applications and the joy in discovering and understanding its ideas and results.
