Summary
Cornerstone Elementary School is a K–4 school in Wooster, OH, in northeast Ohio, serving 347 students in the Wooster City district. Its 2025–26 school rank is 977th of 1,560 (37th percentile, 2 stars), below the district’s overall 66th-percentile standing. It serves a high-poverty population: 79.54% free/reduced lunch in 2024–25, with a 15.8 student-teacher ratio and chronic absenteeism at 14.2% in 2025–26, above the district’s 13.5%.
Among nearby schools, Cornerstone has the lowest rank percentile: Kean Elementary School is at 89, Melrose Elementary School at 70, Parkview Elementary School at 71, and Orrville Elementary School at 45. Within the same district, Kean, Melrose, and Parkview all post higher 2025–26 proficiency rates in every tested subject/grade shown. Kean’s free/reduced lunch rate is 29.71% versus Cornerstone’s 79.54%, so contexts differ, but Melrose (52.99%) and Parkview (50.38%) have moderate poverty and still outperform Cornerstone. Cornerstone’s student-teacher ratio is lower than most nearby schools, suggesting class size is not the main differentiator; its chronic absenteeism is the highest among the nearby set.
Cornerstone has improved from a low base, moving from 1 star in 2021–22 through 2023–24 to 2 stars in 2024–25 and 2025–26, while chronic absenteeism fell from 20.3% in 2022–23 to 14.2% in 2025–26. Math shows the clearest recovery: Grade 4 math reached 64.7% in 2025–26, only 2.6 points below the state, and Grade 3 math reached 58.2%. ELA is the sharper weakness: Grade 3 ELA fell to 55.7% and Grade 4 ELA to 54.4%, both roughly 7–8 points below the state. Subgroup effectiveness for low-income students is 52nd percentile (3 stars) and special education is 49th percentile (2 stars), both improved from 2023–24. Overall, this high-poverty school is trending upward, but its biggest opportunities are ELA, attendance, and closing the gap with same-district peers.
