Summary:

The San Lorenzo Unified district serves approximately 7,700 students across 16 schools in the San Lorenzo, Hayward, and San Leandro areas, ranging from elementary through high school, including a continuation school.

Performance varies widely across the district, with Arroyo High standing out as the top performer, achieving a 91.7% graduation rate and test scores well above state averages despite serving a high-need population. Among elementary schools, Bay Elementary leads in academic proficiency. In contrast, several schools, including Hesperian Elementary, Colonial Acres Elementary, and Edendale Middle, are ranked in the bottom 5% of California schools and require significant support.

The district faces challenges with chronic absenteeism, averaging 23%, and middle school performance is a particular concern. Interestingly, higher per-student spending does not guarantee better results, as seen at Royal Sunset (Continuation), which has the highest spending but the lowest outcomes. The success of Arroyo High demonstrates that strong outcomes are achievable within the district's context.
