Located just outside Calgary in the foothills of the Rocky Mountains, Strathcona-Tweedsmuir School (STS) is Alberta’s only independent Kindergarten–Grade 12 International Baccalaureate (IB) Continuum World School, offering the Primary Years Programme (PYP), Middle Years Programme (MYP), and Diploma Programme (DP).

At STS, learning is driven by curiosity, inquiry, and a commitment to excellence. Through the IB framework, students develop the intellectual independence, global perspective, and character needed to thrive in a complex and changing world.

Our distinctive 220-acre foothills campus near Calgary provides an exceptional setting for learning that extends beyond the classroom. Students engage in a rich program that includes outdoor education, STEM and innovation, fine and performing arts, athletics, and leadership development through the Round Square global network. Small class sizes and a close-knit community allow students to be known, supported, and challenged.

STS is also home to the Centre for Excellence and Leadership in Teaching and Learning, advancing innovation in education, and STAND School, a hybrid learning program expanding access to high-quality IB education.

A member of Canadian Accredited Independent Schools (CAIS), STS prepares students not only for post-secondary, but for lives of purpose, responsibility, and impact.

Guided by the motto Nil Nisi Optimum — Nothing but our best, the STS community strives to help every student flourish.
