Celebrating 50 years

In 1971, a group of forward-thinking, courageous leaders and educators broke ground on a new campus in a remote, rural area just south of Calgary, Alberta. Little did they know that this tiny school with big ideas would go on to become the gold standard of independent private education in Canada − and around the world. 

Flourish 2031

Marking its 50th anniversary, Strathcona-Tweedsmuir School (STS) is embracing a new strategic plan that honours a strong foundation of academic excellence, trailblazing innovation, and a vibrant and engaged community, while forging a courageous new path towards a flourishing school and community for years to come.
