Summary

Cottonwood Creek is a K–8 school in Dublin, California, serving 1,023 students in an area with nearby schools in Dublin, Pleasanton and Livermore. Its 2025–2026 proficiency rates are above state and district levels in English language arts (ELA), math and science, but results have declined from earlier years. The central takeaway is that Cottonwood Creek remains a high-performing school, while its recent declines—especially in science—are worth watching.

Compared with 10 nearby schools, Cottonwood Creek ranks third in ELA, fourth in math and sixth in science. Its proficiency rates are 84% in ELA, 84% in math and 69% in science, compared with nearby-school averages of 76%, 76% and 64%. It also exceeds Dublin Unified by 6 points in ELA, 10 in math and 9 in science, and the state by 35, 45 and 33 points, respectively. Math has the largest lead over the district and state; ELA has the biggest advantage over nearby schools. Fifth-grade science is a notable weak spot: 63%, about 2 points below the district’s 65%, while seventh-grade ELA and math stand out at 92% and 91%.

All three subjects have fallen since 2022–2023: ELA is down 6 points, math 3 and science 3, including a 7-point science drop in the latest year. Even so, SchoolDigger rates the school at the 97th percentile with 5 stars in 2025–2026, down from the 100th percentile in 2022–2023 and 2023–2024. One notable subgroup result is SchoolDigger’s 76th-percentile ranking for how well the school serves Asian Students, compared with its overall 97th percentile; that subgroup ranking fell 14 points since 2023–2024. Context measures include a 22.9 student-teacher ratio in 2024–2025, below the nearby-school average of 24.5, and 7% chronic absenteeism in 2025–2026, compared with 12% districtwide and 18% statewide. The school reported 13% free/reduced lunch eligible in 2024–2025; these figures provide context, not an explanation for achievement.
