The Department of Mathematics & Computer Science seeks to graduate students who can: appropriately analyze a wide variety of mathematical and computing problems, understand and apply relevant theory and technology to solve real-world problems, develop and implement insightful and efficient solutions, and effectively communicate both abstract ideas and practical solutions.

Entering students take a placement test in mathematics prior to enrolling in courses. The test results in conjunction with other criteria are used to place students in an appropriate mathematics course. Advanced placement credit in calculus, statistics, and computer science is possible for students with strong AP scores.
