Summary:
Newcastle, California, has four schools serving kindergarten through grade 8: Harvest Ridge Cooperative Charter, Newcastle Charter, Ophir STEAM Academy, and Newcastle Elementary. Results are available for all four in 2024–2025, but only three in 2025–2026. The most important finding is that every school was above state results in all three subjects in 2024–2025, and the three with newer results also beat the state in every subject.
Newcastle Charter is the strongest overall in the latest results, leading the three schools with 2025–2026 scores at 78% in English language arts (ELA), 66% in math, and 74% in science. It scored 13 points higher than the lowest school, Ophir STEAM Academy, in ELA, 9 points higher in math, and 14 points higher in science. Ophir was still above the state in every subject. Newcastle Elementary fell between them in all three. In 2024–2025, Harvest Ridge Cooperative Charter had the lowest results in all three subjects, while Ophir had the strongest science result and Newcastle Elementary led in math.
Results improved on average across the three schools with scores in both years: about 1 point in ELA, 5 in math, and 4 in science. Newcastle Charter rose in all three subjects, while Ophir STEAM Academy was mixed, gaining 5 points in math but falling 7 in ELA and 9 in science. Ophir’s all-grades results also hide grade-level differences: its grade 7 math result was 82%, versus 38% statewide, while grade 3 ELA was 41%, versus 44% statewide. SchoolDigger ranked Newcastle Charter at the 90th percentile with 5 stars in 2025–2026; Newcastle Elementary was at the 81st percentile with 4 stars, and Ophir at the 65th percentile with 3 stars. For context, the reported free/reduced lunch eligible shares in 2024–2025 were 12% at Harvest Ridge, 18% at Newcastle Charter, 21% at Ophir, and 13% at Newcastle Elementary; these figures do not form a simple pattern with results.
