Sunnyside Elementary School in Bonita serves grades K through 6 as part of the Chula Vista Elementary School District, located on San Miguel Road in the 91902 ZIP code near Sweetwater Road. The campus enrolls 443 students with a 21:1 student-teacher ratio and earned a California Distinguished School Award, a recognition that underscores the same academic rigor families reinforce through supplemental instruction at San Diego Learning Center. CVESD's biliteracy initiative reaches Sunnyside through structured English-learner support and dual-language programming aligned with the district's recognition from the San Diego County Office of Education Biliteracy Symposium. CAASPP proficiency data show 45 percent of students meeting or exceeding standards in mathematics and 50 percent in English language arts, with the LEAD enrichment program supplementing core academics through arts and technology modules. The school's physical-education curriculum connects to Bonita's broader youth-recreation network, including structured swim instruction at Loma Verde Aquatic Center less than two miles away. Facilities include a dedicated STEM lab and a visual and performing arts rotation that feeds into Bonita Vista Middle School's advanced elective tracks within the CVESD-to-SUHSD feeder pattern.
