Our Take: Keystone International Schools

our takeOne 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.

Principal's Message


Ivana Djuric, Principal

Learning is a lifelong experience.

We all had tough times when we were in high school. We did not know what we wanted to do with our lives, we did not understand the importance of certain subjects, we did not see how it would all come together eventually. I was no different. 

Even in the most doubtful of times of success, I persevered, I went back, resolved to succeed, and developed a strategy. I graduated from University and went on to Teacher’s College. To this day, I am a student, improving my knowledge of education delivery and management. I learned to build self-esteem, grounded in self-awareness rather than image. My experience allows me to understand students’ mind-set – those far from home and those who are home, those with learning differences and those who learn conventionally.   

I understand that choosing a school can be one of the most challenging and difficult decisions a family needs to make, as it really is an investment in your child’s future. I would encourage each family to look for the school that best suits the needs and interests of their child. A school should offer an abundance of opportunities for students to explore, experience, learn, find their strengths and to become the very best person they can. 


We are a Community...

Connected by students, their families, teachers and administrators.  As a principal, I strive to encourage intellectual bonds, stimulate curiosity and be the academic catalyst for this community. Students, teachers and parents are always welcome to talk to me. 

I’m proud to say that at Keystone, we have a collaborative learning environment. We teach our students to master learning. Our teachers are creative with instruction and continually learn about how our students best learn. We empower everyone in our community, push intellectual boundaries, enjoy the freedom to experiment, strive for personal bests and create leadership opportunities. We are an academic team with our very own brand of "edutainment".  

I warmly welcome you to visit and discover firsthand what makes Keystone International Schools' education special. 



Curriculum Progressive

Primary Curriculum: Progressive

What Keystone says: We encourage experiential learning and academic, theoretical learning; the marriage of the two makes us unique. Our students are prepared for the rigors of university, while acquiring practical life skills. This combination makes them valuable in the global workplace. Student-centred learning focuses on the student’s needs, abilities, interests and learning styles, with the lecturer as a facilitator of learning; intentional-learning develops students’ explicit understanding of their own approach to learning as well as confidence in their discipline-specific knowledge-base in order to confidently address generic skills and metacognitive functions.

  • Approach:

  • Pedagogies and subject courses:

  • Mathematics Equal Balance

      These math programs feature an equal balance of “Traditional” and “Discovery” methods.

    Science Inquiry

      Inquiry-based science emphasizes teaching science as a way of thinking or practice, and therefore tries to get students “doing” science as much as possible -- and not just “learning” it. Students still learn foundational scientific ideas and content (and build on this knowledge progressively); however, relative to expository science instruction, inquiry-based programs have students spend more time developing and executing their own experiments (empirical and theoretical). Students are frequently challenged to develop critical and scientific-thinking skills by developing their own well-reasoned hypothesis and finding ways to test those hypotheses. Projects and experiments are emphasized over textbook learning. Skills are emphasized over breadth of knowledge.

    Literature Equal Balance

    Humanities and Social Sciences Equal Balance

    Foreign Languages Communicative

      The communicative method of language acquisition emphasizes the use of the target language in authentic contexts. The approach commonly features interactive group work, games, authentic texts, and opportunities to learn about the cultural background of the language. Drills and quizzes may still be used, but less frequently than with the audio-lingual method.

    • Languages Offered: • ESL

    Fine Arts Creative

      Creative arts programs are studio-driven. While historical works and movements may still be taught to add context to the program, students mainly engage in making art (visual, musical, theatrical, etc). The goal is use the actual practice of art to help educate students’ emotions, cognition, and ethos.

    Computers and Technology Heavy integration

      A major effort is made to integrate the development of digital literacy throughout the curriculum and in everything students do. Digital literacy is understood to be a fundamental skill in the 21st century: it therefore follows, the idea goes, that teachers should find ways to connect every lesson back to technology. Effort is made to ensure the use of technology is meaningful and advances students’ skills beyond what they would otherwise be from using computers outside the classroom.

    Sex and Health Education Ontario curriculum
    Topics covered in sex and health education: This information is not currently available.

    What Keystone says: We are partners with the LGBTQ community in education.

    Mostly value-neutral

    By and large, we teach sex education free of any particular moral or ethical standpoint. We try not to impose any particular values or value systems (such as social, political, or ideological values) on our students when teaching sex and related issues.

    Fairly value-based

    Sex education is sometimes taught from a particular moral or ethical standpoint. Sometimes particular values or value systems (such as social, political, or ideological values) are invoked when teaching sex and related issues.


    This includes a range of positions. A traditional approach might, for example, go as far as emphasizing the nuclear family and complete abstinence from sex before marriage. Alternatively, this approach might simply involve placing less emphasis on sex outside of the context of marriage and more emphasis on abstinence. Or finally, it might just involve focusing less on sex outside of the context of marriage.


    This might mean more emphasis is placed on the importance of such things as social equality, diversity, and choice in sex education.

    31 % of Our Kids' schools use a progressive approach for sex and health education

    Curriculum Pace Student-paced

    • Standard-enriched
    • Accelerated
    • Student-paced

    The main curriculum pace is non-standardized and is HIGHLY responsive to the pacing of individual students, (via differentiated instruction, differentiated assessment, etc). In theory, some students outpace the default/normalized curriculum, while others spend periods "behind schedule" if they need the extra time.

    Flexible pacing:

    Flexible pacing style = offered
    Subject-streaming (tracking)
    Multi-age classrooms as standard
    Ability-grouping (in-class) as common
    Frequent use of cyber-learning (at-their-own-pace)
    Regular guided independent study opportunities
    Differentiated assessment

    What Keystone says about flexible pacing: This information is not currently available.

    Academic Culture Supportive

    • Rigorous
    • Supportive

    A school with a “supportive” academic culture focuses more on process than short-term outcomes: academic performance is a welcomed side-benefit, but not the driving focus. This does not mean the school lacks standards, or has low expectations for its students: a school can have a supportive academic culture and still light the fire of ambition in its students. It does mean, however, the school provides a less intensive culture than schools with a “rigorous” academic classification, and is focused more simply on instilling a love of learning and life-long curiosity.

    What Keystone says: This information is not currently available.

    Developmental Priorities Social, Emotional

    Primary Developmental Priority: Social
    Socially aware and active citizens, motivated to change the world (or their community) for the better.

    Secondary Developmental Priority: Emotional
    Emotionally intelligent and confident individuals, capable of leading both themselves and others.
