Our Perspective

How we see Keystone School

One of the resources of Keystone International Schools is the city itself, something that administration has very consciously built into the programs. Toronto has a wealth of resources, of course and Keystone strives, rightly, to make the most of them. While not a preparatory school in name, the program nevertheless addresses itself to a student population preparing for success at university. Supports are in place for international students, and the school adopts an international gaze, looking well beyond the school walls, educating students to be adept at international communication and engagement. The ideal student is one able to thrive within a diverse, collaborative academic environment.

How Keystone School sees itself

The school administration answered our questions

Who are you, as a school?

"Keystone fosters a project-based, experiential learning environment in which students gain knowledge and skills to become responsible, socially conscious, and independent world citizens. With our enhanced program and holistic approach to education, students acquire the qualities and abilities needed for a successful life full of purpose and joy. Our aim is to ignite a passion for life-long learning in our students, while simultaneously inspiring responsibility for the self, the community, and the world."

What do you do differently and uniquely well?

"Our small classes with an average size of 14 students per class provide an individualized Academic Program which ensures that each student is seen, valued, and challenged.

Our project-based learning programs cater to the varied interests and skills of our students where they discover new capacities for critical thinking and forming independent judgments."

To your knowledge, why do families choose your school over others?

"Keystone offers students a home-like environment where each student can express his/her feelings and ideas freely. A balanced distribution of domestic and international students ensures that students become open-minded, respectful and authentic adults."

What aspect of your school is underappreciated?

"We have worked to establish a very close network of communication at Keystone that we feel is unique to our school. From our founder, to our principal, to our administrator, to our teachers, everyone is present at the school each day to build and strengthen bonds and connections with the students. If a student is ever in need of guidance from any member of our academic team, we are always there to provide hands-on, individualized support."

What might families find surprising about your school?

"We are a family-oriented school that fosters interaction between students and teachers. We encourage students to feel that we are all a family, and that they are not simply at Keystone to get their education and go home again. Once a part of the Keystone family, you are part of it for life."

Message from school leadership

Doa Demirsu-Doran, Principal
B.Sc., MBA

Welcome to Keystone International School, a dynamic, boutique school, in the heart of Toronto.

We strive to involve students in their own learning experience. Teachers are not lecturers but are facilitators in the classrooms. Our inquiry-based, holistic approach to education encourage students to take action and become life-long learners. We always remind students that every subject has a relation to the real world. Whenever we can get away from the classroom, we make sure to do that; it’s far more interesting to go check out some super structures to think the physics behind it, see live art pieces and discuss them at the museum, or play logic games to calculate probability for math class. In Economics or Business, we observe a product over time to understand the effects of demand and supply. All these experiments keep students interested and makes learning easier, fun and most importantly permanent.

At Keystone, we nurture our students to be well-rounded and intuitive individuals while challenging them to excel academically. Our culturally diverse environment prepares our students for the future when they will be collaborating with others at a global level.
