Summary

Ruth Grimes Elementary is a K-6 public school serving 606 students in Bloomington, CA, and it stands out as a strong performer within the Colton Joint Unified School District despite the district's overall challenges.

The school has made remarkable progress, especially in improving student attendance, cutting chronic absenteeism from over 42% to just 11.7% in three years. Academically, it consistently outperforms its district, with students more than twice as likely to be proficient in math compared to the district average. It shows particular strength in supporting English Language Learners and students from economically disadvantaged backgrounds, achieving results that rank well above state averages for these groups. However, the school has identified a need to improve outcomes for students in special education and to address a growing performance gap between male and female students.

When compared to nearby schools, Ruth Grimes is a top performer within its own district, significantly outranking others like Walter Zimmerman Elementary and Crestmore Elementary. The only nearby school that ranks higher is Samuel W. Simpson Elementary in the Rialto Unified district, though Ruth Grimes maintains a better attendance record. With stable, improving scores and effective use of its resources, Ruth Grimes represents a notable success in serving its community's needs.
