Christian Unified Schools South Bay in Chula Vista provides TK-through-eighth-grade private education at 482 L Street, operating as the South Bay campus of the Christian Unified Schools of San Diego system. The curriculum integrates biblical worldview instruction across all subjects, pairing faith-based academics with enrichment disciplines in the same tradition as supplementary programs such as Mathnasium. Physical education, choral music, intramural sports, and instrumental band round out the academic program for approximately 215 enrolled students on the L Street campus. A dedicated TK and kindergarten junior campus launched in August 2025, expanding the school's early-childhood footprint alongside Chula Vista's broader network of early-learning centers such as Children's Choice Academy. The campus maintains a 21-to-1 student-teacher ratio with technology-integrated classrooms, weekly chapel services, and a structured ministry-service requirement embedded across the K–8 academic sequence.
