The Junior School at Trinity College School is for students Grades 5-8. The staff and teachers at the Junior School work diligently to ensure the best educational experience for each child, providing diverse opportunities for personal and intellectual growth. In a small, supportive and challenging environment, the teachers motivate the students to explore their strengths, in turn fostering character, confidence and individual achievement. It is also the Junior School's responsibility to develop requisite skills to meet the oncoming challenges and expectations of high school.

Our students are active participants in academics, arts, athletics and co-curricular activities and come to Trinity College School from Port Hope, Peterborough and many towns and cities within the Northumberland and Durham regions. TCS students embrace the opportunities provided inside and outside of the classroom; our teachers work closely with students to nurture good study habits, critical thinking and sound observation skills. Our teachers are committed to their students and their parents; we believe communication with parents is of vital importance. Junior School students learn the value of academic success, good decision making and good citizenship.

The essential ingredients of a TCS education are: academic vigour, co-curricular breadth and attention to the well-being of the whole person.
