San Dieguito Union High School District headquartered on Encinitas Boulevard has administered public secondary education across North County San Diego's coastal communities since 1936. The district's 13,000-plus enrollment spans five middle schools and five high schools serving families from the Encinitas, Cardiff, Solana Beach, Del Mar, and Rancho Santa Fe elementary feeder districts, with special-education and developmental referral networks connecting to providers such as Believe Pediatric Therapy in the Encinitas service area. District-wide assessment data show 67 percent of students meeting math proficiency and 78 percent meeting reading proficiency on California state benchmarks, outcomes driven by a school-choice model that allows any resident student to apply to San Dieguito Academy or Canyon Crest Academy alongside their boundary high school. Canyon Crest Academy has held the #1 California high-school ranking since 2018, and the district's IB World School designation sits at La Costa Canyon High School. Safe Routes to School infrastructure and bicycle-commuting partnerships involve outfitters like Trek Bicycle Encinitas, supporting pedestrian and cycling access across all 11 campuses. Approximately 1,010 staff members operate across a combined budget anchored by per-pupil expenditure rates that fund AP, honors, college-prep, AVID, CTE pathway, and alternative-education programming at Sunset High School in Encinitas.
