Summary
Eastside Elementary serves 423 students in grades K–6 in Lancaster, California. Its 2025–26 proficiency rates were 30% in English language arts (ELA), 26% in math and 30% in science; all three were above the district rates but below state rates. The clearest concern alongside these improving scores is attendance: 35% of students were chronically absent, compared with 18% statewide.
Compared with nearby schools reporting scores, Eastside stands out most in science and math: it had the highest results in both, while its ELA result was second-highest. Its rates were also above the eight-school nearby averages in science (15%), math (16%) and ELA (22%). Compared with the Eastside Union Elementary district, Eastside was ahead by 20 percentage points in science, 9 in math and 6 in ELA. Still, it trailed the state by 6 points in science, 13 in math and 20 in ELA, making ELA its largest state gap. Chronic absenteeism was 2 points below the district rate, but far above the state rate.
Proficiency has risen in all three subjects since 2022–23: by 11 points in ELA, 16 in math and 20 in science. The gaps with state results narrowed in each subject, although the latest science score jumped 19 points from the previous year, a rise to watch over time. SchoolDigger ranked Eastside at the 27th percentile statewide with 1 star in 2025–26, up from the 5th percentile in 2022–23; it ranked ahead of nearby schools with reported results, but its statewide standing remains low. Eastside reported 96% free/reduced lunch eligible in school year 2024–25, the highest rate among nearby schools reporting that measure for the same year; its 23.5:1 student-teacher ratio was middle-of-the-pack locally. SchoolDigger’s subgroup rankings differed notably: English learner students were at the 72nd percentile in 2023–24, versus 19th overall that year, while African American students were at the 1st percentile in 2025–26, versus 27th overall.
