A women-owned private school in Encinitas's Cardiff-by-the-Sea area, Encinitas Country Day School's Manchester Avenue campus serves transitional kindergarten through eighth grade near San Elijo Lagoon. The TK-through-eighth-grade continuum builds from Montessori foundations into project-based middle-school coursework, with wellness referrals connecting school families to area pediatric providers including Natalie D. Muth, MD, MPH, RDN, FAAP. On-campus facilities include a Vernier wireless-equipped science lab, media center with online research access, a dedicated library, and organic gardens adjacent to a conservation area with native coastal-sage habitat. The school's curriculum correlates to California State Standards while layering Montessori hands-on instruction through elementary grades, transitioning to problem-based collaborative projects and nationally-normed spring testing at the middle-school level. Environmental science programming leverages direct access to the San Elijo Ecological Reserve and farm-to-school partnerships with organizations like Coastal Roots Farm that reinforce botany and sustainability lessons. Middle-school electives incorporate Spanish I and II instruction, performing arts through the campus Polestar Performing Arts Academy, and Vernier sensor-based lab experiments spanning chemistry, physics, and environmental monitoring.
