Sharing a campus with Sierra School of San Diego at 6460 Boulder Lake Avenue, Springall Academy K-12 operates as a separate instructional track within the SESI school system in San Carlos, San Diego. The academy carries a K-through-12 designation spanning elementary, middle, and high school grades, and its programming targets students whose behavioral, social, or emotional needs require a structured alternative to traditional public-school placement. Boulder Lake Avenue sits in San Carlos's 92119 ZIP between Navajo Road and the eastern slope of Cowles Mountain, placing the campus within the residential corridor that also houses The Charter School of San Diego — a separate independent-study option for students who learn outside a conventional classroom schedule. SESI's evidence-based model integrates academic instruction with behavioral therapies, life-skills training, and workforce development, and credentialed specialists deliver IEP-aligned coursework in small-group settings. The Springall name dates to the pre-merger era before 2020, when Springall Academy and Sierra Academy operated as distinct schools on the same site, each serving different diagnostic populations. The merger consolidated staffing and expanded cross-disciplinary collaboration between teachers and therapists. San Carlos's proximity to Cowles Mountain and Lake Murray gives the campus access to outdoor learning environments that support physical education and nature-based therapeutic programming. Art Smarts in San Carlos provides community art instruction that complements the structured creative-arts programming available within the SESI curriculum. The school maintains wheelchair-accessible entrances and parking, and the 92119 ZIP anchors a family-oriented residential zone where specialized-education campuses serve students referred from districts across San Diego County.
