International Baccalaureate: The PM Way

At Purcell Marian, students have the opportunity to take a variety of IB classes — from History of the Americas to Environmental Systems and Societies. These two-year courses are designed to create lifelong learners, with an approach to teaching and learning that goes beyond memorizing facts and formulas. Our IB classes are lively, challenging, and student-centered, a place for Cavaliers to pursue their own interests and take pride in hard work.

The IB Diploma

Students who enroll in the full IB course load as juniors are eligible to pursue the IB Diploma, a diploma issued directly by the International Baccalaureate Organization and highly regarded by university admissions officers around the world.

Inclusive, Rigorous, Holistic

At the Castle, IB is also inclusive, offering a rigorous, holistic education to all Cavaliers. Starting with the class of 2026, all Purcell Marian students will graduate with at least one IB course: IB Language and Literature. This course will replace all existing PM English courses at the 11th and 12th grade level and ensure that every student benefits from an IB education.
