Summary

Allen Avenue Elementary serves 467 students in grades K–5 in San Dimas, within the Bonita Unified area. The central finding is that the school’s proficiency rates were above California’s in all three reported subjects in 2025–2026, but below district rates in each.

Compared with eight nearby K–5 schools, Allen ranked fifth of nine in English language arts (ELA), seventh in math, and fifth in science. Its math result—62%, versus a nearby-school average of 68%—is its weakest nearby comparison, even though math is its strongest subject relative to the state: 62% versus 38%, a 23-point advantage. ELA was 63%, compared with 49% statewide and 73% in the district; science was 50%, compared with 36% statewide and 60% in the district. Fourth grade stands out as a concern: Allen ranked eighth of nine nearby schools in both fourth-grade ELA and math.

Results have moved in different directions over time: from 2022–2023 to 2025–2026, ELA rose from 60% to 63% and science from 40% to 50%, while math dipped from 64% to 62%. Chronic absenteeism also fell substantially, from 34% in 2021–2022 to 8% in 2025–2026, below district and state rates. SchoolDigger ranks Allen 1,053rd of 5,804 California schools, at the 82nd percentile with four stars—up seven percentile points from the prior year. Its 21.8:1 student-teacher ratio in 2024–2025 was the second-lowest among 11 nearby schools. Allen reported 37% free/reduced lunch eligible in 2024–2025. SchoolDigger’s statewide percentile for Low Socio Economic Status Students, a measure of how well the school serves that group, rose from 67 to 94 between 2024–2025 and 2025–2026; the school’s overall percentile rose from 75 to 82.

Open Quote Terrible principal and office staff. They are always rude and unwelcoming to parents and students. This is definitely the worst elementary school in the district. Debbie Grenier should be fired. The students deserve a caring, empathetic principal. Close Quote
