Summary:
Zip code 95658 has four elementary schools, all serving kindergarten through grade 8, and their reported all-grades proficiency rates are above California’s in every subject in 2024–2025 and 2025–2026. Across the three schools with 2025–2026 results, the average was 71% in ELA, 62% in math, and 67% in science—about 22, 23, and 31 percentage points above the state, respectively. Science is the area’s strongest subject relative to state results, and the most important current finding is that Newcastle Charter leads in all three subjects.
Newcastle Charter scored 78% in ELA, 66% in math, and 74% in science in 2025–2026, leading the other reporting schools by about 10, 7, and 10 points on average. It was also 29, 28, and 38 points above state results in those subjects. Ophir STEAM Academy was lowest among the three in each subject that year, at 65% in ELA, 57% in math, and 60% in science; its scores trailed Newcastle Charter by 13, 9, and 14 points. Leaders differed in 2024–2025: Newcastle Charter led ELA, Newcastle Elementary led math, and Ophir led science. Harvest Ridge Cooperative Charter had the lowest result in all three subjects that year.
Results rose on average from 2024–2025 to 2025–2026 among the same three schools: 1 point in ELA, 5 in math, and 4 in science, though individual trends differed. Newcastle Charter improved in all three subjects, while Ophir’s ELA and science fell by 7 and 9 points even as math rose by 5. SchoolDigger’s percentile rank rose from 81 to 90 for Newcastle Charter, but fell from 90 to 65 for Ophir; Newcastle Elementary moved from 89 to 81. School context also varies: 2024–2025 free/reduced lunch eligible shares ranged from 12% at Harvest Ridge to 21% at Ophir, while reported student-teacher ratios ranged from 14.0 at Newcastle Elementary to 28.6 at Newcastle Charter. These are observations about school context, not explanations for test results; Harvest Ridge has no 2025–2026 test results in the supplied data.
