Summary

Henry Dalton Elementary serves 333 students in kindergarten through fifth grade in Azusa, in the Azusa Unified area. Its clearest academic concern is fourth grade: just 15% of students were proficient in both ELA and math in 2025–26, compared with averages of 34% in ELA and 32% in math at six other nearby Azusa Unified schools.

Across all grades, ELA is the school’s weakest subject relative to the state, district and nearby schools: 29% were proficient, versus 49% statewide, 33% in the district and 40% at nine other nearby schools. Math is a relative strength compared with the district, with 33% proficient versus 25%, but it was below the state’s 38% and nearby schools’ 36%. Science is another local bright spot: 25% were proficient, above the district’s 21% and the nearby average of 23%, though below the state’s 36%. Among the seven Azusa Unified schools in the comparison, the school had the second-highest science result.

Over four years, math improved from 26% proficiency in 2022–23 to 33% in 2025–26, while ELA slipped from 32% to 29%; science rose from 21% to 25%, with substantial year-to-year variation. Attendance remains a concern: chronic absenteeism was 28% in 2025–26, the highest among the nearby schools supplied, despite falling 17 points since 2021–22; recent results have hovered at 26%, 28% and 28%. SchoolDigger places the school at the 33rd percentile and gives it two stars, below the 42nd-percentile average of the other nine schools. Its 2024–25 student-teacher ratio was 21.4, below those schools’ 23.0 average. The school reported that 77.2% of students were free/reduced lunch eligible in 2024–25. One notable subgroup result: SchoolDigger ranked the school’s effectiveness for English Language Learner Students at the 69th percentile in 2023–24, compared with its overall 49th percentile that year.
