School Notes
- School Motto: Enter to Learn. Go Forth to Serve.
- School Mascot: Storm
- Every school has its own personality. SLS families say there is a tangible warmth on our campus. The main entrance captures the spirit of our wonderful community with two essential plaques-a Henry James' quotation, set in stone in our Be Kind Plaza, and our motto, inscribed over the main doorway: Enter to Learn, Go Forth to Serve.
- At SLS, exceptional academics and strong community connections are inextricable. Our alumni cite relationships with teachers as the top value of their SLS education, while parents speak of the skills and responsiveness that distinguish our faculty.
- The SLS mission is an exceptional education that inspires a deep love of learning, a strong moral compass, the commitment to serve, and the confidence to lead. Our Leading with Humanity curriculum advances this mission by helping students develop exceptional leadership abilities.
- Many families are attracted to SLS' blend of traditional education and forward-thinking environment. New ideas and concepts in education are embraced and risks taken. Educators and students have the freedom to explore what it means to learn and grow.
- The SLS designLab offers "mastery" (moving forward as you master concepts) engineering courses, a fully-equipped fabrication lab, and school-wide, and design-thinking challenges. We also have blended and online learning options and many project-based learning experiences including a January Term where students step out of traditional class routines to work full-time, in groups, on "real world" problems.
- Students appreciate the chance to try new things and maybe even discover a new passion. We have an extensive visual and performing arts program, and many opportunities for self-expression and exploration.
- SLS has additional signature programs including eighth-grade Declamations-a rite of passage where each student immerses in a semester-long research project and presentation-and our Upper School Scholars Program where seniors may apply to pursue a year-long research initiative, ultimately presenting their findings at our annual Scholars Symposium.
- SLS is a secular (non-religious), private day school serving grades 5-12. Located in New Canaan, Connecticut, our school attracts families from 40 towns throughout Connecticut and New York. A combination of challenging academics and truly exceptional community support distinguishes SLS and encourages our students to go above and beyond their own expectations. We offer an inclusive environment where differences in race, culture, and personal beliefs are embraced as assets that enhance education.
