Mission: “Commit, Learn, Thrive.”

Review: “The kids have bought into what we’re asking of them in terms of problem-solving and going into that deeper level of thinking, and it’s really showing gains in terms of our outcome. We also personalize students’ timetables for next year – what are their strengths and weaknesses, what courses do we think they would strive in. We’re looking towards the future. We’ve extended our after-school literacy program. Last year alone, we had 160 students who signed up in Grade 10, and we were able to run five classes. We also brought it back to Grade 9s, so they’re introduced to it in the first semester so that they’re familiar with the language used and they’re familiar with the task. We took that anxiety away from the test.”
