Summary

Twin Oaks High is a small public high school serving grades 9–12 with about 192 students in the San Marcos Unified district, which is generally high-performing, but this school faces significant challenges.

The school is distinguished by extremely low academic proficiency, with only about 10% of students meeting standards in English and 1% in math, which is far below district and state averages and the lowest among nearby schools, including Foothills High which shares its campus. A major contributing factor is a severe chronic absenteeism rate of 68%, meaning most students miss a large amount of school. Despite these academic struggles, graduation rates have historically been strong, suggesting the school has support systems to help students earn diplomas even if they haven't mastered grade-level standards on state tests.

Twin Oaks High spends significantly more per student than other schools in the district, like San Marcos High or Mission Hills High, which supports its small class sizes, but outcomes remain poor. Its profile—high poverty, low enrollment, and high needs—is more similar to continuation schools such as Major General Raymond Murray High in Vista Unified, indicating it may serve a particularly at-risk population within the comprehensive school system.

Twin Oaks has an amazing staff. If students attend, they will be given full support to earn credits and gain self-confidence. Kids who have not found a comfortable niche in huge local high schools have found a great, supportive school to help them to be successful. Close Quote
