United by a common vision to build a better world together as educators, ten schools came together in 2012 and founded the Strategic Alliance of Global Educators (SAGE).
The alliance has since grown to include members from different parts of the world:
- Avenues: The World School, New York
- Oulunkylän Yhteiskoulu
- Nanshan High School
- Pathways World Schools
- Øregård Gymnasium
