Summary:

The 94521 zip code in Concord, CA, is served by nine public schools spanning grades K-12, including five elementary schools, two middle schools, and two high schools across the Mt. Diablo Unified district and the independent Clayton Valley Charter High District.

Academic performance varies significantly across these schools. Clayton Valley Charter High stands out as the top performer with high test scores, a 95.8% graduation rate, and remarkably low chronic absenteeism. Among elementary schools, Silverwood Elementary ranks highest, while El Dorado Middle faces the greatest challenges with the lowest rankings and test scores in the area. The other Mt. Diablo Unified schools generally cluster in the middle percentiles statewide.

Key differences include a wide range in per-student spending, which does not directly correlate with performance, and a strong link between lower chronic absenteeism and higher achievement. The data shows a notable performance gap between the charter high school and the traditional district schools, with Concord High showing lower proficiency rates and higher absenteeism than Clayton Valley Charter High. This creates a community with diverse educational outcomes where school choice and student attendance patterns appear influential.
