Summary:
ZIP code 92867 has two Orange High and Richland Continuation High, both serving grades 9–12 in Orange Unified; enrollment is 1,728 at Orange and 165 at Richland. The clearest overall finding is that Orange leads in all three 2025–26 tested subjects, but both schools’ proficiency rates are below the state’s.
Orange High stands out for stronger test results and completion measures: it leads Richland Continuation High by 26 percentage points in ELA, 9 points in math and 22 points in science. Orange’s proficiency rates are 39% in ELA, 14% in math and 26% in science; Richland’s are 13%, 5% and 4%. Both are below state rates, with Orange trailing by 10 points in ELA, 24 in math and 10 in science, and Richland trailing by 36, 33 and 32 points. Orange’s graduation rate is 98%, versus Richland’s 80%; dropout rates are 2% and 14%, respectively. Attendance is a concern at both: chronic absenteeism is 29% at Orange and 83% at Richland, compared with 18% statewide.
Recent changes are mixed rather than a uniform improvement. From 2024–25 to 2025–26, the two schools’ equal-weight average proficiency rose by 3 percentage points in ELA and 4 in math, narrowing the average gap with the state by 3 points in each; science rose by 2 points, but its average gap widened by 1 point. SchoolDigger’s statewide percentile rankings rose from the 30th to the 35th percentile at Orange and from the 7th to the 11th at Richland, though Orange had been at the 37th percentile in 2024–25. In 2024–25, free/reduced lunch eligible shares were similar—87% at Orange and 88% at Richland—while student–teacher ratios were 20.8 and 11.4. These contextual differences do not explain the schools’ results; Richland’s continuation-school setting and smaller enrollment are worth keeping in mind when comparing its figures.
