Summary

Summer Lake Elementary is a public K-5 school serving about 595 students in Oakley, part of the Oakley Union Elementary district, which ranks below average statewide.

Academically, Summer Lake's test scores in English, Math, and Science are below the California average, but it performs better than the district average and outperforms some local schools like Laurel Elementary and Oakley Elementary. However, it trails behind higher-performing schools in neighboring districts, such as Isaac R. Montanez Elementary in the higher-ranked Brentwood Union district. A significant challenge is chronic absenteeism, with nearly 24% of students missing too much school—a rate higher than most nearby schools and one that likely impacts learning.

The school shows notable strengths in supporting students with special needs and operates with mid-range spending compared to peers, suggesting efficient use of resources. Performance varies considerably by grade level, with 4th grade doing relatively well in English but 5th grade struggling in Science. While the school's overall state ranking has slightly declined, it serves a diverse student body with a moderate level of economic need, similar to some local schools that achieve different academic results, indicating that factors beyond demographics are at play.
