Upper School begins in Grade 9 with Courses in Grades 9 – 10 serving as preparation for International Baccalaureate courses in Grades 11 and 12.

Courses in Grades 11 and 12 are offered at both Higher (HL) and Standard level (SL), as well as Credit level, to cater to students who may or may not choose to take the full IB diploma program. Credit level courses expose students to the rigors of the IB program but with less stringent assessment criteria.

All Upper School students are placed into Homeroom classes that meet briefly each morning. During this time, teachers serve as mentors and have the opportunity to get to know their students outside of assessed, academic areas. The Homeroom teacher also serves as the immediate point of contact for general communication between home and school. Teachers conduct attendance and read morning announcements.
