Summary:
Zip code 94518 in Concord, California, contains one public middle school, Oak Grove Middle, serving grades 6-8 within the Mt. Diablo Unified School District.
This school faces significant academic challenges, consistently ranking in the bottom 10% of all California middle schools for the last several years. Proficiency rates in core subjects are dramatically lower than both district and state averages; for example, only about 9% of students are proficient in mathematics, and proficiency in English Language Arts declines sharply from 6th to 8th grade. The school's chronic absenteeism rate of 33.5% is also notably higher than average, which is a serious concern for student engagement and learning.
Parents should be aware that Oak Grove Middle serves a high-need population, with nearly 88% of students eligible for free or reduced-price lunch. While the school operates within a generally higher-performing district, its outcomes are far below district norms across every measured category, indicating it may require targeted support and intervention to improve student success.
