Summary

Allen (Decima M.) Elementary is a San Bruno K–5 school serving 396 students in the San Bruno Park Elementary District. Its results are mixed: math is above the state average, while ELA and science are below it. The clearest academic concern is science, where Allen’s proficiency is 12 percentage points below the nearby-school average.

Compared with the 10 nearby K–5 schools, Allen is below their average in all three subjects: 46% in ELA versus 51%, 44% in math versus 51%, and 32% in science versus 43%. It scores higher than four nearby schools and lower than six in each subject; science is its largest local gap. Math is nevertheless a relative strength: it is 6 points above the state average and 2 points below the district. ELA is 3 points below the state and 4 below the district; science is 4 below the state and 6 below the district. Fifth grade stands out as a concern: ELA proficiency is 40%, 10 points below third and fourth grade, and math is 37%, 11 points below the district. Chronic absenteeism is also high at 27%, compared with 20% in the district and 18% statewide; only Belle Air Elementary is higher among nearby schools.

Results have improved since 2022–2023, rising 5 points in ELA, 12 in math, and 13 in science, although ELA and science dipped in the latest year. SchoolDigger places Allen at the 58th percentile statewide for 2025–2026 (rank 2,435 of 5,804; 3 stars), down from the 62nd percentile the year before. The 2024–2025 student–teacher ratio was 23.2:1, close to the nearby-school average of 23.6:1. Allen reported 65% free/reduced lunch eligible in 2024–2025, the second-highest share among the 11 schools. One notable SchoolDigger subgroup result is its 41st-percentile ranking for Low Socio Economic Status Students in 2025–2026, compared with 58 overall; the subgroup ranking had been 68 the year before.
