Summary

Rio Del Oro Elementary is a K-5 public school serving 564 students in the Plumas Lake community, and it stands out as a consistently strong performer within its region.

The school's academic results are a key strength, with students outperforming both the Plumas Lake Elementary district and state averages in English and Math. This is particularly notable when compared to several nearby schools, such as Ella Elementary and Olivehurst Elementary, which often score well below state averages. Rio Del Oro also excels in student attendance, with a chronic absenteeism rate of just 7.3%, which is less than half the state average and contributes significantly to its success. While the school achieves this with moderate per-student spending, a comparable nearby school, Marcum-Illinois Union Elementary, posts higher test scores but also has a significantly wealthier student population and more teachers per student.

There are areas for growth, as science scores are only modestly above average and there is a noticeable dip in 4th-grade English scores. Compared to its closest peer, Cobblestone Elementary in the same district, Rio Del Oro maintains a slight academic edge despite nearly identical resources and student demographics, suggesting differences in school culture or instructional effectiveness. Overall, Rio Del Oro is a stable and efficient school that delivers strong results for its community.
