Summary

Mary Endres Elementary School serves 431 students in grades 1–5 in Woodstock, where several nearby elementary schools provide useful local comparisons. In 2025–2026, its English Language Arts (ELA) results were above the state level, while math and fifth-grade science were below it. The main takeaway for parents is that ELA is a relative strength, but math remains the clearest academic weakness.

ELA is stronger than math, but the school’s all-grade results are not among the best in the district. In 2025–2026, 64% of students were proficient in ELA—8 percentage points above the state, but 9 below Woodstock CUSD 200 and 2 below the average of five other Woodstock elementary schools. Fifth-grade ELA stands out: 73% were proficient, 18 points above the state and 1 point above the district. Math proficiency was 36%, 4 points below the state, 7 below the district and 2 below the local peer average. Fifth-grade science was close to state and district results at 46%, but slightly below the other Woodstock schools’ 48% average.

Scores have improved overall since 2023–2024: ELA rose 9 points, from 55% to 64%, and math rose 16 points, from 20% to 36%. However, ELA fell 6 points from its 2024–2025 high, and the latest math result remains below state and district levels. SchoolDigger places the school at the 48th percentile with 2 stars for 2025–2026, the lowest percentile among the six ranked Woodstock elementary schools; the others range from the 49th to the 55th percentile. As context, 56% of students were free/reduced lunch eligible in 2024–2025, compared with a 45% average at five other Woodstock schools, and the 2024–2025 student-teacher ratio was 17.9:1, higher than the ratios reported by those peers. SchoolDigger’s statewide effectiveness ranking for Female Students fell from the 63rd percentile in 2024–2025 to the 33rd in 2025–2026, a notably weaker relative standing than the school’s overall 48th percentile. Its ranking for Low Socio Economic Status Students also dropped, from the 75th to the 49th percentile.
