Senior School - Reaching new heights

Senior School students benefit from choice.

They can choose to study a combination of International Baccalaureate (IB) Diploma Programme (DP) courses and Alberta Education courses or they can pursue the full IB DP. Regardless of their choice, they will engage in an academic program of excellence which promotes inquiry, challenges students to do their best, optimizes technology, and prepares them for success in university and beyond.

Senior School co-curricular programs are also about choice while also encouraging students to develop a sense of civic duty, global perspective and empowerment through a variety of unique experiences.

To maintain a well-balanced education, students are encouraged to follow their hearts and try new things outside the classroom. From student-led clubs, athletics, speech and debate, outdoor education, organizing activities for younger students, fine and performing arts, the annual school musical production, local community service activities, and international service projects they truly are inspired to explore their possibilities.
