of 2,761 California Middle Schools

Better than 12% of California middle schools

Summary

Ruth O. Harris Middle is a public school serving about 560 students in grades 7 and 8 in Bloomington, California, as part of the Colton Joint Unified School District, but it faces significant academic challenges with proficiency rates in English, math, and science well below state averages.

Despite these academic struggles, the school has a clear strength: it has dramatically improved student attendance, with a chronic absenteeism rate of 14.2% that is notably better than the district and state averages and far lower than nearby schools like Mission Middle (30.2%) and Rialto Middle (30.7%). The school also spends more per student ($23,380) than all comparable schools in the area and has a lower student-teacher ratio, yet these resource advantages have not yet translated into stronger test scores.

When compared to other local middle schools with similar student populations, such as Southridge Technical Middle and William G. Jehue Middle, Ruth O. Harris Middle's academic performance lags behind. The school's ranking has been volatile over the years, and there is an unusual pattern where 8th graders outperform 7th graders in English, but 7th graders do better in math, suggesting potential areas for curriculum review and alignment.
