Saburo Muraoka Elementary School in Chula Vista's Eastlake area serves grades K through 6 within the Chula Vista Elementary School District, California's largest K-6 district. The campus at 1644 Santa Alexia Ave anchors a TK-through-sixth-grade pipeline in the Otay Ranch community where after-school enrichment providers such as Aqua-Tots Swim School Otay Ranch extend physical-education programming beyond the bell schedule. Dedicated in July 2017 as CVESD's 46th school and the newest campus in San Diego County at the time, Muraoka Elementary honors Saburo Muraoka, a Japanese-American agricultural leader whose family helped shape Chula Vista's farming heritage. With an enrollment of approximately 1,104 students and 44 full-time-equivalent teachers producing a 25:1 student-teacher ratio, the school emphasizes biliteracy leadership as part of a district recognized by the San Diego County Office of Education, a focus that complements supplemental math instruction available through Mathnasium in the surrounding Eastlake corridor. The curriculum integrates collaborative project-based learning with CAASPP proficiency rates of 51 percent in mathematics and 64 percent in English language arts, both above CVESD and statewide averages.
