Summary

Rio Valley Charter is a K-12 alternative public school in Lodi, California, serving 714 students with a focus on strong outcomes in graduation and attendance.

The school excels in two critical areas: getting students to graduation and ensuring they are in class. With a graduation rate of 94.8%, it far outpaces the state average and most nearby alternative schools like John F. Cruikshank Junior (37.5%) or one.Charter (32.3%). Even more impressive is its near-perfect attendance record, with a chronic absenteeism rate of 0.0%, which is exceptional compared to rates as high as 65.9% at schools like Walton Development Center. Academically, students perform at or above state averages in English and Science, a notable achievement given that over 65% of students qualify for free or reduced-price lunch.

Rio Valley Charter achieves these results efficiently, spending about $14,782 per student, which is roughly half the cost of many comparable schools in the San Joaquin County Office of Education. While math scores are an area for growth, the school's consistent performance, especially in high school science, and its cost-effective model make it a standout in the Rio Valley Charter District. Its success is shared with other high-performing Lodi charters like Vista Oaks Charter and Valley Robotics Academy, suggesting a supportive regional environment for alternative education.
