Welcome!

In schools around the world, the IB Diploma Programme challenges 11th- and 12th-grade students through inquiry-based coursework. Students learn to ask stronger questions, build evidence-based arguments, conduct meaningful research, and connect classroom learning to the wider world. IB emphasizes depth, perspective, and purpose, helping students develop the thinking, writing, and problem-solving skills they need for college and beyond.

My name is Barret Bell, and I am the Director of the International Baccalaureate Program at Purcell Marian. Since joining the Castle in 2017, I have been involved with all things IB. I love working with students, families, and staff to ensure that our IB program reflects, serves, and celebrates our community.

This IB Program Hub is designed to help you understand how IB works at Purcell Marian. If you are new to IB, start with A Visual Overview to get the big picture. If you are an underclassmen choosing courses, visit Choosing Your IB Path and Courses & Faculty to see what options are available and how students can prepare.

Whether you are just beginning to explore IB or are already part of our community, this site is meant to make the program easier to navigate. If you still have questions, please reach out!
