Pre-K through grade 2: Where Learning Forward Begins

On the sheltering green grounds of Sierra Canyon's Lower Campus, our expert early childhood teachers nurture your child's intellectual and moral development in equal measure, providing an unusually firm foundation for learning and growing.

Cultivating vegetables in our garden (and then eating them) or finding out what money means and practicing ways to use it, your child connects with academic studies in real ways from day one. As they work and play with eager classmates from all walks of life, Sierra Canyon students build academic, emotional, and cultural agility to carry them forward through our Lower, Middle, and Upper Schools.

We invite your child to begin a joyful life of learning with us. To find out more, please explore our early learning curriculum and schedule a tour. 

Grades 3-6: The Next Steps in Learning Forward

As your child takes their next steps through our Lower School, we design every experience to fully engage all wonderful, wondering dimensions, so our students come to understand how they learn best.

On the expansive, leafy grounds of our 17-acre Lower Campus, your child builds curiosity and confidence through active questioning, real-world problem-solving, and thoughtful small-group work, alongside classmates from uncommonly diverse backgrounds. Students can explore California's Missions from multiple perspectives, build and race a solar car, compete on the swim team, play in our rock band, and travel to Olympic National Park with their teachers and classmates.

All the while, our students enhance their innate compassion through our intentional character education program, so they know how learning can benefit others, not just themselves.

Guided and inspired by caring, imaginative faculty members, your child discovers how, what, and why they love to learn. By the end of the transitional grade 6 year, our students have grown into strikingly self-aware, self-directed young thinkers and citizens, ready for the galvanizing challenges of our Middle School.

To find out more, please explore our grade 3-5 curriculum, the transitional grade 6 curriculum and schedule a tour.
