Summary
Sunnydale Elementary is a 469-student school serving grades K–7 in Lancaster, California, in the Lancaster Elementary District. In 2025–2026, students were proficient at rates of 32% in English language arts (ELA), 19% in math, and 17% in science—better than the nearby-school averages, but below the state in every subject. The most important finding is that these state gaps remain substantial: about 18 points in ELA, 20 in math, and 19 in science.
Compared with nearby schools, the school’s clearest strength is ELA: it ranked third among ten schools with same-year results in both ELA and math, and fifth in science. Its scores were about 14 points above nearby averages in ELA, 5 points above in math, and 3 points above in science. It also outperformed the district by 7 points in ELA and 4 in math, while science was essentially level, about a third of a point lower. Third grade was a particular high point: 46% were proficient in ELA and 34% in math, both the strongest results among the supplied nearby schools with third-grade results. Across all grades, however, the state proficiency gaps show that local comparisons do not tell the whole story.
Results have improved since 2022–2023, rising about 10 points in ELA and 9 points each in math and science, although science scores have fluctuated from year to year. SchoolDigger gives the school a 1-star rating and a 21st-percentile statewide ranking for 2025–2026, up from the 4th percentile in 2021–2022; it ties for the highest standing among nearby schools apart from the virtual academies. The 2024–2025 student-teacher ratio was 21.3, the lowest among nearby schools, and the school reported 88% of students as free/reduced lunch eligible that year, compared with a nearby average of 89%. SchoolDigger’s statewide ranking for how well the school serves African American students was at the 42nd percentile in 2025–2026, versus 21st overall; its ranking for English Language Learner students fell from the 78th percentile in 2018–2019 to the 28th in 2021–2022. These group rankings reflect relative school standing, not individual students’ results.
