Summary

Twin Oaks Elementary is a K-5 public school serving 648 students in the San Marcos Unified district, representing a solid, mid-performing option in the community with a 3-star rating.

The school stands out for its impressive improvement in student attendance, reducing chronic absenteeism from over 36% to just under 11% in three years, a rate now better than the district and state averages. Academically, it performs close to state averages in English and Math, but shows a particular strength in science, outperforming both the district and state. When compared to nearby schools with similar or higher levels of economic need, such as La Mirada Academy and San Marcos Elementary, Twin Oaks achieves significantly stronger academic results. However, it trails behind other district schools with lower poverty rates like Paloma Elementary and Richland Elementary.

An interesting pattern at Twin Oaks is that fifth graders consistently score much higher on state tests than third and fourth graders, which is unusual compared to typical district trends. The school's overall ranking has stabilized in recent years after a period of decline, and it operates with a mid-level budget that is efficiently used to achieve its results. While the school serves all students adequately, performance data indicates varying levels of success across different student groups, suggesting areas for continued focus and growth.
