Summary

Los Altos Elementary is a 391-student K–5 school in Hacienda Heights, part of the Hacienda la Puente Unified district. Its 2025–26 results put math closer to state and district averages than the other subjects, but its most important finding is that it scored below state, district, and nearby K–5 averages in ELA, math, and science.

Math is the school’s strongest subject relative to the state and district, while ELA is its weakest in local comparisons. Los Altos had 43% proficiency in ELA, 37% in math, and 30% in science; the state results were 49%, 38%, and 36%, respectively, and district results were 51%, 40%, and 35%. That leaves Los Altos 6 points below the state in ELA, 1 point below in math, and 6 points below in science. Across eight nearby K–5 schools, averages were 56% in ELA, 50% in math, and 40% in science, putting Los Altos 13, 13, and 10 points lower. Third-grade math is a relative bright spot: 48% proficiency was 2 points above the state, while fourth- and fifth-grade math were below the state by 9 and 8 points.

Results have weakened compared with earlier years, especially in math: from 2022–23 to 2025–26, ELA fell 2 points and math 7, while science was essentially flat. In the latest year, ELA and math each dropped 9 points, even as science rose 7. SchoolDigger rates Los Altos at the 48th statewide percentile with 2 stars for 2025–26, down 18 percentile points from 2021–22. Its 21.7 student-teacher ratio in 2024–25 tied for the lowest among nearby K–5 schools, but has not coincided with stronger test results. In 2024–25, 67% of students were free/reduced lunch eligible, above the nearby-school average of 56%; this is context, not an explanation for scores. Chronic absenteeism improved from 36% in 2021–22 to 17% in 2025–26, below the state and district. SchoolDigger’s measure also gives English Language Learner students an 84th-percentile ranking for 2023–24, compared with the school’s 58th-percentile overall ranking that year, a notable relative strength.
