Summary

Timber Point Elementary is a K-5 public school serving 362 students in the community of Discovery Bay, operating within the Byron Union Elementary school district.

The school presents a mixed academic profile, performing solidly in mathematics where it exceeds both district and state averages, but its overall statewide ranking places it in the middle tier. A notable and unusual pattern is its performance with different student groups; the school has shown particular strength in supporting one group of students while another group's performance lags behind, creating an atypical achievement dynamic. Furthermore, chronic student absenteeism has been volatile in recent years, currently sitting higher than the district average. Compared to its sister school, Discovery Bay Elementary, Timber Point serves a student population with less economic need but achieves lower overall test scores and rankings.

When looking at nearby schools in other districts, such as Old River Elementary in the Knightsen Elementary district, Timber Point's performance is lower despite similar size and a more economically advantaged student body. The school's historical performance has also gradually declined from higher percentiles over the past decade. While it spends less per student than many neighboring schools in the Brentwood Union district, its math results are competitive, suggesting efficient resource use in that specific subject area.
