Best Public Schools in Zip Code 94509

This analysis covers 18 public schools in the Antioch, CA area (zip code 94509), serving grades K-12 across traditional, charter, and alternative settings within districts like Antioch Unified and the Contra Costa County Office of Education.

Overall, the area's traditional district schools face significant academic challenges, with most ranking in the bottom 30% statewide and showing proficiency rates in English and math that are well below California averages. Chronic absenteeism is a major concern, averaging 34.6% across all schools, which is much higher than the state average of 19.4%. However, there are standout performers: Antioch Charter Academy and Antioch Charter Academy II consistently rank higher, have exceptionally low chronic absenteeism (2.0% and 3.4%), and post stronger test scores, while Rocketship Delta Prep shows strength in mathematics and science.

Key challenges include a severe mathematics performance gap, particularly in middle and high schools, and high rates of economic disadvantage. Schools needing the most support are Marsh Elementary and Antioch Middle, which rank in the lowest percentiles. The data suggests that successful models exist within the charter schools, which achieve better outcomes despite lower per-student spending, indicating that targeted interventions on attendance and curriculum could benefit the wider district.
