Riverside County Office of Education

The four schools in Riverside County Office of Education include two high schools and two alternative schools, serve grades K–12, and enroll 1,481 students across different settings. In 2025–2026, their average proficiency was 11% in English language arts, 4% in math and 4% in science, compared with 49%, 38% and 36% statewide. The most important takeaway is that no school was close to the state average in any of the three subjects.

CBK Charter led the group in all three subjects, with 28% proficient in ELA, 7% in math and 13% in science; even so, it remained 22, 32 and 23 percentage points below the state, respectively. At the other end, Riverside County Community had the lowest ELA and math results, at 3% and 1%, and tied with Riverside County Juvenile Court at 0% in science. Riverside County Special Education was near CBK in math at 6%, but had 4% in both ELA and science.

Recent changes were mixed: CBK gained 4 percentage points in math and 6 in science from 2024–2025 to 2025–2026, while Community fell 3 points in both ELA and math and 5 in science; Juvenile Court improved 5 points in ELA and 2 in math. The overall ELA and math averages were nearly unchanged, while state results rose, widening the average gaps to 38 points in ELA and 34 in math. SchoolDigger ranked CBK in the 23rd percentile with one star and Community in the 5th percentile with zero stars in 2025–2026. CBK also had the highest reported student-teacher ratio, 26.9, while Special Education had the lowest, 8.1. All four reported free/reduced lunch eligible figures for 2024–2025, ranging from 55% at Special Education to 97% at Juvenile Court; these are context, not an explanation of scores. Graduation and attendance figures add another consideration: CBK’s graduation rate was 52%, versus 88% statewide, and Juvenile Court had the group’s lowest chronic absenteeism at 20%, compared with 57% at Community. The schools serve different grade spans and settings, so comparisons are not fully like-for-like.
