As the TK-through-first-grade campus of Riverview International Academy, Winter Gardens Elementary School in Lakeside anchors the early-childhood entry point for San Diego County's only trilingual immersion program at 8501 Pueblo Rd. The intimate single-grade-band setting serves the district's youngest learners before they advance to the Riverview campus for grades two through five, with family enrollment coordinated through community hubs that include Lakeside Community Center on Vine St. Spanish immersion follows a 90/10 model in TK and kindergarten, while Mandarin immersion operates at 50/50 English-Mandarin, with both tracks incorporating third-language enrichment to build multilingual foundations. The campus employs Restorative Practices and the 7 Keys of Excellence framework for conflict resolution and cultural proficiency, drawing from the same early-childhood pipeline that includes Montessori East County Preschool & Infant Care on Maine Ave. Guided by the Lakeside Union School District's dual-immersion mandate, the site prepares students to pursue the California State Seal of Biliteracy through a continuous K-5 language-acquisition sequence split across the two-campus model.
