Summary
Arlanza Elementary serves 431 students in grades K–5 in Riverside, California, as part of Alvord Unified. In 2025–2026, 24% of students were proficient in ELA, 15% in math and 8% in science. The most important concern is that proficiency remains low across all three subjects, with science the lowest.
Arlanza trails both the state and district in all three subjects: its ELA proficiency was 25 points below the state and 15 below the district; math was 24 and 11 points lower; and science was 28 and 19 points lower. Compared with six nearby Alvord K–5 schools, Arlanza was third-lowest in ELA and lowest in math and science. Those schools averaged 30% in ELA, 22% in math and 22% in science, putting Arlanza 6, 7 and 14 points below those averages, respectively. Fourth-grade ELA was a particular local weakness at 17%, the lowest among nearby schools’ fourth-grade results; Arlanza’s math proficiency was 10% in grade 4 and 8% in grade 5, also below every nearby school’s result at those grades.
There are encouraging signs in attendance and recent test changes: chronic absenteeism fell from 36% in 2021–2022 to 11% in 2025–2026, 7 points below both the state and district rates. From 2024–2025 to 2025–2026, ELA rose 8 points and math 5, while science fell 4; over the longer period, the state gaps narrowed slightly in ELA but widened in math and science. SchoolDigger ranked Arlanza in the 7th percentile statewide and gave it 0 stars in 2025–2026, the lowest standing among nearby schools with rank data. Its student–teacher ratio was 23.2 in 2024–2025, near the nearby average of 22.9; 97% of students were free/reduced lunch eligible that year, the highest figure among nearby schools. SchoolDigger’s statewide rankings show stronger relative standing for Homeless Students, at the 48th percentile versus 7th overall in 2025–2026, and for English Language Learner Students, at the 32nd percentile versus 14th overall in 2023–2024.
