San Dieguito Adult School at 710 Encinitas Boulevard provides adult-education programming under the San Dieguito Union High School District. The school's noncredit English as a Second Language, high-school equivalency, and citizenship courses transitioned in 2016 to the oversight of MiraCosta College San Elijo Campus's Continuing Education division, integrating San Dieguito's legacy curricula into the college's regional credentialing pipeline. GED and high-school-diploma preparation is offered in both English and Spanish, alongside vocational-certificate tracks and enrichment courses for older adults. The Encinitas Boulevard campus sits within SDUHSD's southern service area covering Encinitas, Solana Beach, Rancho Santa Fe, Del Mar, and Carmel Valley — the same geographic corridor that feeds academic-support enrollment at Sylvan Learning of Encinitas on North El Camino Real. The campus is part of the Coastal North County Adult Education Consortium, a state-funded collaboration between SDUHSD, MiraCosta College, Carlsbad Unified, and Oceanside Unified focused on adult basic education, workforce readiness, and immigrant-integration pathways.
