Summary

Odyssey Charter is a high-performing K-8 school serving 463 students in Altadena, part of the highly-ranked Odyssey Charter District, and stands out for delivering strong academic results for a community with a mix of family incomes.

The school consistently scores well above state averages, with about 80% of students proficient in English and 65% in math, and it achieves this with moderate per-student spending. It serves as a notable middle ground in the area: it significantly outperforms nearby schools in the Pasadena Unified district, like Madison Elementary, while serving a more economically diverse population than the elite, higher-spending schools in the La Canada Unified district, such as La Canada Elementary.

Parents should note a few key points: the school has seen a recent rise in chronic absenteeism, which it is working to address, and there is a noticeable dip in 6th-grade math scores that the school is likely focused on improving. Overall, Odyssey Charter is a strong option that demonstrates a charter school can provide a high-quality education effectively and efficiently within a diverse community.
