Summary

Rocketship Mosaic Elementary is a highly-rated public charter school serving 528 students in grades K-5 in San Jose, consistently ranking in the top quarter of all California elementary schools while serving a community with significant economic need.

The school stands out for its exceptional academic results, particularly in math and English, where it significantly outperforms both the state average and nearby traditional public schools like Jeanne R. Meadows Elementary. It is remarkably effective in supporting English learners and students from low-income families, achieving these strong outcomes with lower per-student spending and a higher student-teacher ratio than surrounding schools in districts like Franklin-McKinley Elementary and Alum Rock Union Elementary. Furthermore, the school has an exceptionally low chronic absenteeism rate, a key factor in its success.

While Rocketship Mosaic excels in many areas, parents should note a significant drop in student performance in 5th grade and notably low science proficiency. Compared to another charter in the network, Rocketship Los Suenos Academy, Mosaic achieves higher test scores and much better attendance. The school's performance within the Rocketship Mosaic Elementary District demonstrates that similar student populations can achieve different outcomes, highlighting the impact of specific school models and practices.
