The IB curriculum was a decision making factor for us. The way it is administered at Sunnybrook is very structured. You see how students learn to think and to inquire. These are the foundational tools they need to possess as they grow and move to higher grades.
My son is keenly interested in what he is learning in the classroom, and that translates into the questions and discussions we have at home. His teacher has been very supportive and encouraging. In my son's words, his teacher is very "nice" and "funny", and he is very comfortable to approach him with any questions or concerns he may have. There was one incident where my son was acting out a bit in class. The teacher was quick to correct the behaviour, and notify myself in order that I can further enforce the teachings. He is also very fair in his distribution of homework. He assigns a reasonable amount, and also breaks down the work load to help encourage students to effectively time manage and prioritize.
