Licensed under California Community Care #376700685 with capacity for 137 children, Sacred Heart Academy Preschool runs a whole-child curriculum combining play-based, sensory, and structured activities for students ages two through five at 4895 Saratoga Avenue in OB. Sacred Heart's Core Knowledge framework emphasizes sequential content mastery over the self-directed exploration model used at Adventures in Montessori Ocean Beach down the corridor, positioning the parish campus as the structured-curriculum anchor on the peninsula's early-education stretch. Opened in 2010 as an extension of an academy operating on the same site since 1950, the preschool organizes five classrooms by developmental stage so teachers can target fine-motor, gross-motor, and cognitive benchmarks in small groups. Kindergarten readiness drives the final pre-K year, bridging students toward Ocean Beach Elementary School and other local primaries through phonics, number sense, and social-emotional foundations built across a uniform-dress, portfolio-tracked academic environment. The most advanced classroom layers multi-step project work, early literacy assessments, and structured transition routines that mirror a kindergarten schedule.
