SLI The Sidney Ledson School, Private school in Toronto, ON

The school was founded in 1982 in order to create a program that reflected the work of Sidney Ledson, an author and expert on topics relating to teaching technology and motivation. His methods gained traction internationally, at the core of which is the idea that we needn’t wait to introduce children to new skill areas (specifically around language and numeracy) and the sooner we start, the better. His books on reading expanded the concept and application of phonics, and his work remains a foundation for the language arts programs at the institute today. There, and elsewhere, the approach intends to challenge students to reach further, to expand and improve their abilities in order to reach their fullest academic potentials. The ideal student is one operating at the top of his or her peer group, and, in the later grades, is preparing for success within university studies.

2. What do you do differently and uniquely well?

At SLI The Sidney Ledson School, we offer a uniquely advanced academic curriculum for Kindergarten to Grade 6 that integrates national-level writing, math, and entrepreneurship contests into core programming. Our students don’t just learn—they apply skills through real platforms. With smaller class sizes and enrichment options such as French, music, and computer science from early grades, each child receives individual attention. Leadership is built through our house system and public speaking opportunities, creating confident, well-rounded learners prepared for elite secondary schools.

3. What tradeoffs has your school made to serve families in this way?

Information not yet available.

4. What key junctures in your school's history have most shaped its present?

Information not yet available.

5. What type of student is a good fit for your school?

SLI is ideal for students who are eager to be challenged and families who value academic enrichment, structure, and measurable growth. Our learners thrive with routine, strong foundational teaching, and early opportunities to present, lead, and compete. The school best fits high-achieving or gifted students, or those who benefit from a structured, accelerated, and well-rounded program that includes advanced math, public speaking, and early exposure to entrepreneurship.

6. Under what conditions would you advise a family against choosing your school?

Families seeking a highly relaxed, play-based environment or minimal academic pressure may not find the best fit at SLI. Our program is fast-paced and focused on skill development, performance, and academic achievement. Parents seeking a school where devices are used throughout the day or where students lead their learning without structure may be mismatched with our emphasis on teacher-guided, high-expectation instruction and regular assessments.

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

Families choose SLI The Sidney Ledson School for its strong academic focus, small class sizes, and accelerated curriculum that offers national contest participation starting in Kindergarten. Many parents tell us they were drawn to our school's track record of academic distinction, especially in writing, math, and entrepreneurship. Compared to other private schools, families appreciate our early introduction to leadership, French, coding, and public speaking—skills often delayed elsewhere. The school’s structured environment, low screen use, and individualized programming for high achievers make it an exccellent choice for families who want more than a standard curriculum.

Both my daughters go to SLI, and they could not be happier. They appreciate the variety of subjects offered as well as the methodologies followed in both classes. Learning and teaching are thorough, personalized to the students' needs and levels of progress. My daughters also love their teachers, as they bring enthusiasm to the materials they share with students and they also demonstrated a high sense of care and commitments to each student . In addition to these characteristics, as a parent, I can see the impact of the self-directed learning that takes place in the classroom, so students take the initiative in their learning journey and own their progress. Neither of them mentioned anything negative about their student experience. They do see it as a second home, and they are happy to go to school every morning.

My children liked their teachers (Ms. Tabacowalla, Ms. Selina & Ms. Yu) so much in the first a few weeks since they started their JK in September 2017, that they looked forward to going to school. These teachers established personal connections with my children, which paved way for them to engage in enriched learning. My children enjoyed the playtime with other kids. It's great that they have playtime between learning sessions. I feel that my children developed social skills through playing with other kids. I like that they have arts and crafts activity daily.

The experience my kid gets is diverse. It is a wholesome learning culture. The teachers are great and connect very well with the students. What do you feel your child likes the best, or appreciates the most, about his/her experience at the school? I see my child grow into a leader and we are proud to have our kid associated with the school. Likewise, is there anything that he or she finds disappointing? We only wish there was larger play ground for kids.

My daughter has loved every teacher who has taught her and that is what she appreciates the most and they are the best about this school.

Son likes the school and teacher. The administrative staff Ms Shivji, Ms Jan, and Ms Kara are all great to work with as are all the staff and teachers. The only opportunity I see is for upgrades to the school in terms of equipment and layout and painting. The school looks very dated but I can imagine it would be expensive to do the upgrades and do not want higher fees for the students so am willing to live with what is there currently.

Our son had a truly amazing experience at Sidney Ledson. At first, he was reluctant to move to a small school, but it ending up being one of the best decisions he ever made. From the helpful teachers to the small class sizes to the immersive academic program, all aspects of the school seemed to fit into place. In this time at Sidney Ledson, our son learned much more than he had in previous years and enjoyed going to school more than ever. He made close bonds with his peers, some of which still exist several years later. Overall, enrolling my our son at Sidney Ledson was one of the best decisions we have ever made.
