About us

We believe in empowering the individuals who will shape our future.

Finding the balance between flexibility and accountability, allowing students to find their individuality.

We are a small high school based in St Francis Bay. We honour a holistic education by teaching a hybrid, international curriculum, with additional, enrichment subjects such as Social Responsibility and Sustainability.

We currently offer middle school Grades 7 – 9, which is completed over 2 years, a Foundation 1 and 2 year. We also offer the International General Certificate in Education (IGCSE), which is a CAPS Grade 10 and 11 equivalent. We look to opening the Advanced Subsidiary (AS) level, which is Grade 12 equivalent, in 2026.

What parents say

Key College has been a great experience for us. Griffin is managing nicely with the workload. The teachers interact well with the children and the small classes make it suitable for individual attention.
