About SLI The Sidney Ledson School

(Formerly known as Sidney Ledson Institute)

SLI The Sidney Ledson School, established in 1980, has consistently excelled in offering an enriched and innovative education for students from Preschool to Grade 6. Our school is uniquely designed for gifted and high-achieving students who thrive on academic challenges and hands-on learning experiences.

Our rigorous curriculum stands out in multiple areas:

  • STEM Excellence: Our students excel in advanced math, coding, and scientific exploration. With instruction in languages like Python and machine learning, along with engineering-based projects, our computer science program prepares students to think critically and solve real-world problems.
  • Entrepreneurship: SLI fosters creativity and leadership through entrepreneurial challenges that not only teach the fundamentals of business but also develop skills in public speaking, problem-solving, and teamwork.
  • Literary Achievement: Our strong literacy program enables students to engage deeply in both creative writing and journalism. Through national writing contests, our students have the opportunity to become published authors at a young age, earning recognition for their literary skills.
  • Science Fairs: Our annual science fairs challenge students to engage in hypothesis-driven research and present their findings, fostering a spirit of inquiry and scientific reasoning.
  • Arts and Music: In addition to academics, our arts and music programs inspire creative expression and practical application, with opportunities for students to explore both theory and practice in music and visual arts.
  • House League System: Beyond academics, SLI cultivates leadership, teamwork, and a sense of community through our house league system. Students earn points for their houses through both academic achievements and character-building activities, encouraging collaboration, responsibility, and healthy competition.

With small class sizes and a focus on individualized learning, SLI ensures that each student’s strengths are nurtured and celebrated. Our students are regularly recognized on national platforms, and these achievements build early confidence that empowers them for a lifetime of success.

SLI The Sidney Ledson School continues to set the standard for academic excellence, preparing students not only for secondary school but for a lifetime of learning and leadership.
