Families searching for an IB school in Toronto are often looking for more than a label. They are seeking deep thinking, global awareness, inquiry-based learning, strong academics, and students who develop confidence, agency, and purpose.

At SLI The Sidney Ledson School, we explored the International Baccalaureate Primary Years Programme (PYP) in depth. We met with IB representatives, reviewed the full framework, and carefully evaluated how it would integrate with our existing program. That process confirmed something important: SLI already delivers the full spirit, structure, and outcomes families value in IB education—and in several areas, we intentionally go further.

The International Baccalaureate has contributed meaningfully to global education. Its emphasis on inquiry-based learning, student agency and reflection, interdisciplinary connections, and global awareness and ethical thinking has helped shape strong learning communities around the world.

Our review process affirmed that these principles are sound—and that they already align closely with how SLI has operated for years.

Families often ask what specifically draws them to IB schools. When we mapped those priorities against our existing program, the overlap was clear.

Inquiry-Driven Learning

Students investigate meaningful questions, test ideas, refine thinking, and present conclusions. Inquiry is embedded across math, science, humanities, and applied projects—not confined to a single framework.

Conceptual and Interdisciplinary Teaching

Learning is intentionally connected across subjects. Students are guided to see relationships between ideas, systems, and disciplines, supporting deep understanding rather than surface coverage.

Student Agency and Ownership

Students are encouraged to think independently, ask questions, make choices in their learning, and reflect on outcomes. Leadership, voice, and responsibility are built into daily classroom life.

Global Awareness and Ethical Reasoning

Through literature, social studies, science, and discussion-based learning, students engage with global issues, perspectives, and ethical considerations in age-appropriate but substantive ways.

Strong Academic Foundations

SLI places particular emphasis on advanced literacy, numeracy, analytical writing, and mathematical reasoning—ensuring that inquiry is grounded in precision, clarity, and academic confidence.

Research, Presentation, and Exhibition-Style Projects

Students regularly complete extended projects that require research, synthesis, communication, and presentation—mirroring the skills families associate with IB exhibitions and culminating assessments.

After careful consideration, SLI chose not to become an authorized IB school. This decision was not a rejection of the philosophy—it was a strategic and educational one.

The IB Authorization Would Not Add Educational Value

The required IB structures, fees, and oversight would largely duplicate practices already embedded into our program. In practical terms, authorization would not enhance student outcomes beyond what SLI already delivers.

Preserving Program Flexibility

SLI values the ability to respond quickly to students’ needs, interests, and strengths. Remaining independent allows us to evolve curriculum, pacing, and enrichment without external constraints.

Choosing Substance Over Branding

We believe families deserve clarity. Our focus remains on what students actually experience, not on paying for a designation when the educational outcomes are already being met and exceeded.

A Deliberate Choice: Investing in Students

Rather than allocating resources to fee-based authorization and ongoing program costs, SLI reserves funds to support student bursaries and ensure a strongly merit-based admissions process.

Our priority is building a learning community defined by curiosity, commitment, and academic integrity.

Many families begin their search with the term IB school because it signals rigor, depth, and future readiness. What ultimately matters, however, is not the label—it is the lived classroom experience.

At SLI, families find inquiry without rigidity, global thinking grounded in strong academics, student agency paired with high expectations, and a learning environment designed around children, not compliance structures.

For many, the realization is simple: the education they hoped to find through IB already exists here—intentionally, thoughtfully, and without compromise.

SLI welcomes students from Toronto and surrounding areas, including:

• North York
• Thornhill
• Don Mills
• Willowdale
• Leaside
• Bayview Glen
• St. Andrew-Windfields
• Richmond Hill
• Scarborough

Our location and small-class approach support families seeking an academically serious elementary experience with depth, confidence-building, and strong community.

We welcome thoughtful families who are exploring IB education in Toronto and want to understand what truly drives student growth. If you are seeking an academically strong, inquiry-aligned school that prioritizes depth, integrity, and merit-based opportunity, SLI The Sidney Ledson School offers a compelling alternative worth understanding.

Nurturing the brilliance in every child.

Is SLI an IB World School?

No. SLI The Sidney Ledson School is not an IB World School and does not offer an IB-authorized programme. This page is intended for families researching IB schools in Toronto and explains how SLI already delivers the learning outcomes and educational priorities many families associate with IB education.

Why do parents searching for IB schools consider SLI?

Families often begin their search with “IB school” because they are seeking depth, rigor, global awareness, inquiry-based learning, and confident, independent thinkers. Many discover that SLI already provides these qualities through a strong academic foundation, interdisciplinary learning, and student agency—without the added layers of external program oversight.

Does SLI follow an inquiry-based approach similar to IB?

Yes. Inquiry is embedded throughout SLI’s program across subjects such as math, science, humanities, and applied projects. Students investigate meaningful questions, test ideas, reflect on outcomes, and present their thinking regularly as part of everyday learning.

How does SLI compare to IB Primary Years Programme (PYP)?

SLI already incorporates many elements families value in PYP, including interdisciplinary learning, student voice, global perspectives, research-based projects, and presentation skills. After reviewing the PYP framework in detail, SLI determined that formal authorization would not add meaningful educational value beyond what students already experience.

Will my child be prepared for IB, enriched, or advanced programs later on?

Yes. SLI students develop strong analytical thinking, communication skills, independence, and academic confidence. These foundations prepare students well for a range of advanced secondary programs, including IB, enriched, independent, and selective school pathways.

What ages and grades does SLI serve?

SLI offers programs from Preschool through Grade 6. The curriculum is designed to challenge bright, motivated learners while supporting their social and emotional development.

Is SLI suitable for gifted or high-achieving students?

Yes. SLI is a strong fit for gifted and high-achieving students, as well as for motivated learners who benefit from small class sizes, advanced academics, and an environment that values curiosity, depth, and independent thinking.

Why did SLI choose not to pursue IB authorization?

After careful review, SLI concluded that IB authorization would largely duplicate practices already embedded in the program. Remaining independent allows SLI to preserve curricular flexibility and direct resources toward student bursaries and merit-based opportunity rather than ongoing program fees.

Where is SLI located, and which areas do families come from?

SLI serves families across Toronto and the Greater Toronto Area, including North York, Thornhill, Don Mills, Willowdale, Richmond Hill, Bayview Glen, Leaside, St. Andrew-Windfields, and Scarborough.
