Our Perspective

How we see Sidney Ledson Institute

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.

Message from school leadership

Ms. Rumina Shivji, Principal
B.Arch. & Educational Specialist

The Sidney Ledson Institute is a visible expression of the philosophy embodied in Sidney Ledson's books, "Raising Brighter Children" and "Teach your Child to Read in 10 Minutes a Day."  Our PK - Gr. 7 Program implements this philosophy at the school to raise IQ, provide enriched academics, and promote self-confidence in our students, to not only succeed, but excel through their primary education, and then through their Alumni years at Toronto's most academically elite secondary and post-secondary institutions.
