Full-Time OAT Students


OAT offers the full high school accredited program at Grades 9, 10, 11, and 12 levels for students to earn their OSSD (Ontario Secondary School Diploma).



As an accredited Ontario high school, we use curriculum created by the Ontario Ministry of Education. Our primary focus is mathematics and sciences, as we cater to students seeking admission into mathematics, science or engineering post-secondary disciplines. At OAT, we go beyond regular curriculum expectations by offering various Technology Workshops and demonstrating to students the overlap between their technical courses. Studying at OAT, students can earn the standard courses required for acceptance into university.  


Quality of Instruction:

Our small class sizes allow for ample individualized support to ensure that students are well-prepared for their post-secondary studies. Through various teaching methods such as hands-on learning, direct instruction, effective questioning, cooperative and project-based learning, we target the diverse needs of our students so they can confidently retain knowledge and apply new skills.


OAT’s faculty is comprised of teachers who are knowledgeable, experienced, and passionate about the Art of Teaching. Our instructors are certified by the Ontario College of Teachers or are graduates from Masters and PhD programs. OAT teachers aim not only to provide the highest level of instruction, but also recognize that teaching is a human-centred profession. Our instructors care about building relationships with students so that learners are comfortable to ask questions and seek extra help whenever needed. To reinforce this close dynamic, at OAT, students and teachers relate to each other on a first-name basis.


Earning a high school diploma is important, but unfortunately the Ontario public education system doesn’t work for everyone. If you are looking for an alternative, OAT is the place to start looking. We are always happy to take on more students, be it for one on one tutoring, single credits, or full-time classes. Our central location at Yonge and Eglinton makes it easy to reach us from anywhere in Toronto and the GTA by public transit. Our school was founded in 2013 by teachers with years of teaching experience, with a vision: to create a learning environment that focuses on the individual students. Whether our students are simply working towards their OSSD or have goals that reach further, we aim to infuse a passion for whatever subject is being taught in the classroom.

At OAT, we pride ourselves on our talented instructors who teach students to have a passion for science and technology. We try to go above and beyond in presenting students with opportunities to learn outside the curriculum. Our goal is not only to teach students the course material for their high school diploma, but also to teach them to enjoy learning the course material themselves. Please contact us today, and we will be happy to answer any inquiries.

Standardized Tests:

As part of OSSD requirements, we offer EQAO (Education Quality and Accountability Office) tests, as needed, in Grades 9 and 10; we also offer the Ontario Secondary School Literacy Course. Additionally, due to interest among many OAT students, we also provide support for writing: 


- SAT Subject Tests (Math Level I and II)

- AP Exams (College Board school code 826335)

- Euclid and CEMC Math Contests


Please don't hesitate to contact us for a full school calendar/policy document.
