Summary:
ZIP code 95660 has 12 schools—eight elementary schools, three high schools and one alternative school—in Twin Rivers Unified. Eleven schools have 2025–2026 test results; their average proficiency is 28% in English, 22% in math and 18% in science, compared with state averages of 49%, 38% and 36%. Results also vary widely from school to school. The most important takeaway is that the area averages fall below state averages in all three subjects, but they do not describe every school equally well.
Different schools lead in different subjects: Creative Connections Arts Academy is near the state average in ELA, with 49% proficiency versus 49% statewide, and its 11th-grade ELA result is 61% versus 57% statewide. Sierra View Elementary leads all-grades math at 35%, just ahead of Creative Connections at 34%; its third-grade math result is 57%, versus 47% statewide. Hillsdale Elementary leads science at 39%, above the state’s 36%. At the low end, Pacific Career and Technology High has the lowest all-grades results in each subject—3% in ELA, 6% in math and 3% in science—well below state results by 46, 32 and 33 percentage points, respectively.
Recent trends are mixed: the area average fell by about 2 points in ELA and by less than 1 point in math from 2024–2025 to 2025–2026, while science rose by about 4 points. As a result, the area’s gap with the state widened by about 2 points in ELA and 1 point in math, but narrowed by about 1 point in science. SchoolDigger’s statewide percentile ranking rose for Sierra View, from 36 to 45 between 2023–2024 and 2025–2026, while Warren A. Allison Elementary fell from 46 to 18. All schools list Free/reduced lunch eligible for 2024–2025; among the K–8 schools, the shares range from 87% at Kohler Tk-8 to 94% at F. C. Joyce Tk-8. These figures provide context, not an explanation for school results; school sizes and grade spans also vary, so comparisons are best treated as a starting point.
