High Schools in San Lorenzo Unified

Summary:

This analysis covers four public high schools within the San Lorenzo Unified school district for the 2024-2025 year, serving grades 9-12 in the San Lorenzo area of California, with enrollments ranging from just over 100 to nearly 1,500 students.

Among these schools, Arroyo High stands out as the district's highest performer, ranking in the 64th percentile statewide with the strongest graduation rate (91.7%), lowest chronic absenteeism (14.7%), and the best test scores across English, math, and science. In contrast, San Lorenzo High and East Bay Arts High face greater academic challenges, with proficiency rates below state averages. Royal Sunset (Continuation), which serves at-risk students, has severe struggles with a 30% dropout rate, 77% chronic absenteeism, and 0% proficiency in math and science.

The data reveals a notable pattern where higher per-student spending does not correlate with better outcomes; Royal Sunset and East Bay Arts receive the most funding but have the weakest academic results. Chronic absenteeism is a strong predictor of performance, with Arroyo's low rate aligning with its success. While the district trails state averages overall, English Language Arts is a relative strength. Parents should note that Arroyo High demonstrates a consistent record of improvement and effective outcomes within the district.
