Summary

Rio Del Mar is a public elementary school serving 499 students in grades K-5 within the Rio Elementary district in Oxnard, CA, which is currently navigating significant changes in its student community.

Academically, the school's overall performance has declined in recent years, but it shows important strengths, particularly in teaching mathematics and in effectively supporting its English Language Learner students, where it excels. However, a major challenge is chronic student absenteeism, which is notably higher than at many neighboring schools like Rio del Sol and Junipero Serra Elementary. Within its own district, Rio Del Mar performs better than several peers, such as Rio Plaza Elementary and Rio Lindo Elementary, especially considering it spends less per student.

When compared to schools in other local districts like Ventura Unified and Oxnard, Rio Del Mar sits in the middle of the pack. Its performance is not as strong as the highest achievers in the area, but it holds its own with efficient use of resources. The school's test scores vary by grade, with third grade being a relative bright spot, suggesting a focus on consistent learning across all grades could be beneficial for future improvement.
