Summary

Altamont Elementary is a well-regarded K-8 school serving 616 students in the high-performing Lammersville Joint Unified district in Mountain House, where it consistently earns strong academic ratings and significantly outperforms California state averages.

Within its exceptional district, Altamont is a solid, middle-tier performer; it trails top schools like Julius Cordes Elementary and Hansen Elementary but performs similarly to peers like Bethany Elementary and ahead of others like Lammersville Elementary. All schools in Lammersville far outpace those in neighboring districts, such as Tracy Joint Unified, highlighting the strength of the district overall. Interestingly, Altamont's chronic absenteeism rate, while lower than the state average, is higher than the district's top schools, representing a key area where improvement could help close performance gaps.

The school shows notable strengths in supporting English Learner and Hispanic students, and it uses its resources efficiently, spending moderately compared to district peers. However, its statewide ranking has slightly declined in recent years, and performance varies by grade level, with third-grade English scores being a relative weakness. For families, Altamont offers a reliably strong education in a community dense with high-quality schools, with specific opportunities to grow by improving attendance and ensuring consistent excellence across all grades.
