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 in high school and beyond. We prepare students for the highest levels of math and science courses at St. Thomas and for their mathematics courses at the university level. 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.
