Summary

Stanley G. Oswalt Academy is a K–8 school in Walnut, serving 879 students in Rowland Unified, near schools in both Rowland Unified and Walnut Valley Unified. In 2025–2026, its all-grades proficiency was 70% in English Language Arts (ELA), 56% in math, and 57% in science, higher in all three subjects than both its district and California. Its most important distinction is consistently strong achievement across subjects compared with the state and district.

Against the 10 nearby schools in the data, Oswalt ranked second of 11 in ELA, third in science, and fifth in math. Its ELA result was 21 percentage points above the nearby average; science was 24 points higher, and math was 14 points higher. ELA is its strongest local subject, while math is its relative weak spot: several nearby schools scored higher, even though Oswalt still exceeded the state and district in math. In grade 7 math, Oswalt had 40% proficiency, compared with 38% statewide. For grade 8, it substantially outscored the other nearby K–8 school, Telesis Academy of Science & Math, in both ELA (72% versus 41%) and math (56% versus 20%). Nearby schools serve different grade spans, so all-grades comparisons are not perfectly like-for-like.

Over four years, math improved from 51% to 56%, ELA was nearly unchanged at about 70%, and science ended where it started at 57% after dipping in between. Oswalt’s lead over the state narrowed by 3 points in ELA and 6 in science, while its math lead widened by 1 point. SchoolDigger places Oswalt at the 84th statewide percentile with 4 stars, up 7 percentile points since 2021–2022. Its 2024–2025 free/reduced lunch eligible rate was 57%, and its student–teacher ratio was 24.7—near the middle of the nearby group, not unusually low. Chronic absenteeism was 9% in 2025–2026, below the district’s 16% and California’s 18%. SchoolDigger’s group rankings show a notable difference in how well the school serves particular groups: its Asian Students ranking was at the 64th percentile, 20 points below its overall percentile, while its Homeless Students ranking was at the 100th percentile, 16 points above overall.
