Summary:
Zip code 93402 in Los Osos, California, is served by three public schools—two elementary and one middle school—all part of the high-performing San Luis Coastal Unified district, with no high school located within this specific zip.
Among these schools, Monarch Grove Elementary stands out as the top academic performer, particularly in mathematics, achieving significantly higher test scores than both district and state averages. Los Osos Middle also performs very well overall, especially in English, though it shows a notable decline in math scores in the higher grades and has a concerningly high rate of chronic student absenteeism. Baywood Elementary, while still above state averages, has the lowest test scores of the three and its statewide ranking has recently dropped, despite having the best student attendance record.
An interesting finding is that Monarch Grove's academic excellence comes despite it having the lowest per-student spending and highest student-teacher ratio in the area, suggesting factors like teaching quality or school culture are key drivers. All schools serve a economically diverse population, and the district context provides strong support. For parents, the area offers quality options, with Monarch Grove being the strongest elementary choice, while the middle school's math performance and absenteeism are areas to watch.
