The Senior School encompasses four years of secondary or high school, beginning in Grade 9 and culminating in Grade 12. During that time, students are exposed to learning in the classroom, on the playing fields, in arts and community service activities and in the daily encounters with other students and teachers. The liberal arts programme is designed to give students a broad and rich exposure to many disciplines and is a reflection of our School's mission to develop habits of the heart and mind for lives of purpose and service.

Students will develop the skills necessary to thrive not only at TCS, but in university, the workplace and in their community. The faculty takes a team approach to this learning. Students are closely monitored and guided and there is an understanding that student success is the primary goal. Experiences in the Senior School are life altering and friendships established there last a lifetime.
