Summary

Isaac R. Montanez Elementary is a K–5 school in Brentwood, California, serving 444 students in Brentwood Union. Its 2025–2026 results were above both the state and district in English language arts (ELA), math and science. Most notably, it had the highest all-grades math proficiency among the 10 nearby schools, at 56%.

The school’s strongest nearby comparison is math: 56% of students were proficient, compared with 41% across the nearby schools, 44% in the district and 38% statewide. ELA proficiency was 58%, second among nearby schools and above the district’s 56% and the state’s 49%. Science was 43%, also second nearby and higher than the district’s 40% and the state’s 36%, though its advantage over those benchmarks was smaller. Math results vary by grade: grades 3 and 4 were the highest among nearby schools, at 69% and 59%, while grade 5 was 40%, third among nearby schools and much lower than Montanez’s grades 3 and 4.

Results have shifted in different directions: from 2024–2025 to 2025–2026, ELA rose by 1 percentage point, while math fell by 4 points and science by 5; the school still exceeded state results in every subject, but its math and science leads narrowed.

Its 24.6 student-teacher ratio was around the middle of the local range. The school reported that 33% of students were free/reduced lunch eligible in 2024–2025.
