Summary

Glassbrook Elementary is a K–6 school in Hayward, California, serving 455 students in Hayward Unified. Its 2025–26 proficiency results were low across English language arts (ELA), math, and science. The clearest concern is that Glassbrook had the lowest ELA and math proficiency among the ten nearby schools, with results also well below district and state levels.

Compared with its benchmarks, science was Glassbrook’s closest subject, while math was its lowest-scoring subject and ELA had the largest gap to the state. In 2025–26, 14% of students were proficient in ELA, compared with 34% districtwide, 49% statewide, and a 38% average among nearby schools. Math proficiency was 6%, versus 22% for the district, 38% for the state, and a nearby average of 28%. Science was 8%, compared with 23% districtwide, 36% statewide, and 24% at nearby schools. Glassbrook’s science result was above Park Elementary’s 5%, but below the other nine nearby schools. Its ELA and math results were also the lowest in the nearby group.

Scores have risen since 2022–23: ELA increased by 2 percentage points, math by 2 points, and science by 1 point. However, state results rose faster, so Glassbrook’s gap to the state widened in all three subjects, especially science. SchoolDigger ranked Glassbrook 5,737th of 5,804 California schools in 2025–26, at the 1st percentile with 0 stars; it remained at the 1st percentile in each of the prior three years. As context, its 2024–25 student-teacher ratio was 24.5, the third-highest among the supplied nearby schools. That year, 83% of students were free/reduced lunch eligible, the highest rate in the nearby group, whose average was 73%; these measures describe context, not a cause of test results.
