Paul Ecke Central Elementary School in Encinitas's Old Encinitas district serves grades K through 6 within the Encinitas Union School District at 185 Union Street. The campus is one of only two EUSD schools offering a Spanish-English Dual Language Immersion program using a 90/10 model that delivers 90 percent of kindergarten instruction in Spanish before shifting toward 50/50 parity by sixth grade, and its outdoor learning includes a School as a Garden program with field connections to Encinitas Community Park on Santa Fe Drive. Approximately 583 students attend across 26 full-time teaching positions at a 22-to-1 student-teacher ratio, with STEM enrichment, art, and yoga woven into the weekly rotation. Bond Measure Z is funding a full campus reconstruction beginning summer 2026, designed by DLR Group and built by Balfour Beatty, with an estimated completion date of fall 2027. Environmental science and botany curricula extend off-campus through field-study partnerships with San Diego Botanic Garden on Quail Gardens Drive, reinforcing the school's garden-based STEM focus. DLI enrollment operates through an annual lottery process requiring a mandatory orientation meeting, with accepted students committing to the bilingual track from kindergarten through the sixth-grade exit assessment.
