Summary:
Zip code 95970 has two schools in Princeton Joint Unified, serving grades K–8 and 9–12 and enrolling 126 students altogether. In the latest year with results for both, 2024–2025, the schools’ simple average proficiency rates were below California’s in all three tested subjects, with the largest gaps in math and science: 14 percentage points below the state in each. The clearest concern across the shared results is that math and science proficiency lagged state rates most.
The schools stand out in different subjects rather than one leading across the board. In 2024–2025, Princeton High had the higher ELA rate, 53% versus 30% at Princeton Elementary, and the higher science rate, 29% versus 9%. Elementary led in math, 30% to 18%. High’s ELA rate was 4 points above the state’s 49%, but its math rate was 20 points below the state’s 37%; Elementary’s strongest relative subject was ELA, while its science rate was 9% compared with 33% statewide. The differences between schools were largest in ELA and science, at 23 and 21 points, respectively.
Elementary’s 2025–2026 results continued that mixed picture: ELA rose to 39% and science to 22%, while math fell to 14%; its gap from the state narrowed by 9 points in ELA and 10 in science, but widened by 17 in math. SchoolDigger’s percentile rank for Elementary rose from 7 to 34, while High’s rose from 12 in 2022–2023 to 52 in 2024–2025. These rankings are separate from subject test results. In 2024–2025, Elementary had 83 students and a 14.8 student–teacher ratio; High had 43 students and an 8.2 ratio. Both schools reported similar free/reduced lunch eligibility that year: 66% at Elementary and 67% at High. Because the schools serve different grade spans and High’s 2025–2026 test results are suppressed, their latest test results cannot be compared directly.
