Full Ranking Detail
childcareinfantkinder
Discovery Isle Preschool — La Costa in San Marcos is a multi-campus, licensed childcare provider serving infants from 6 weeks through Kindergarten, with hours Monday–Friday 7:00 AM–6:00 PM. The center uses the Links to Learning curriculum, a research-based program emphasizing small-group learning and individualized support across core academic and developmental areas, supplemented by enrichment activities including Spanish language exposure, music, art, and hands-on play. Security features include individualized keypad access and private fencing. However, the center's licensing record shows multiple concerns: 1 Type A and 5 Type B citations across inspections, and notably, four complaint investigations recorded between 2024–2025, with two occurring in July 2025 alone—a pattern suggesting elevated recent risk warranting independent due diligence beyond parent reviews.
