Summary

Castlemont High is a public high school serving 719 students in grades 9-12 within the Oakland Unified district, located in a high-need community where nearly all students qualify for free or reduced-price lunch.

The school faces significant challenges, with academic proficiency in core subjects like English and math below 7%, a graduation rate of 64.3%, and a chronic absenteeism rate of 58.2%, all of which are far below district and state averages. The school's performance is particularly low for vulnerable student groups, including those in special education and students experiencing homelessness. Despite a high per-student spending of $30,723 and a favorable student-teacher ratio of 14-to-1, these resources have not translated into stronger academic outcomes for students.

Comparisons with nearby schools highlight a stark contrast. Other schools serving similar student populations, such as Coliseum College Prep Academy (92.6% graduation) and charter schools like East Bay Innovation Academy and Oakland Unity High, achieve dramatically higher proficiency and graduation rates, often with lower per-student spending. Most notably, LPS Oakland R&D Campus shares a building with Castlemont but reports a chronic absenteeism rate of just 1.7% compared to Castlemont's 58.2%, suggesting school culture and programming are critical factors in student success.
