Summary

Stone Bridge is a K-8 elementary school serving 278 students in Napa, California, operating within the small, independent Stone Bridge District.

The school's statewide ranking has declined significantly in recent years, dropping from the 76th percentile in 2019 to the 38th percentile for the 2024-2025 school year, earning it a 2-star rating. This downward trend stands in contrast to the more stable performance of some nearby schools like Pueblo Vista Elementary and Vichy Elementary. A notable concern is a large gender performance gap, with female students ranking in the 59th percentile while male students rank in the 17th percentile. The school also shows inconsistent results across grade levels, with some grades performing well above state averages and others falling far below.

Stone Bridge operates with fewer financial resources than neighboring schools, spending $11,212 per student compared to the $15,000-$17,000 spent by schools in the larger Napa Valley Unified district, and it has a higher student-teacher ratio. Despite serving a student population with a lower percentage qualifying for free or reduced-price lunch than most area schools, its academic performance lags behind several nearby schools that have greater socioeconomic challenges but also receive more funding. However, Stone Bridge does manage chronic absenteeism effectively, with rates well below the state average.
