CUSD 200 reviews Vision 2026 dashboard and new Illinois proficiency benchmarks; board briefed on achievement, interventions and strategic-plan timeline

WHEATON, Ill. — CUSD 200 staff on Oct. 22 briefed the Board of Education’s Committee of the Whole on changes to Illinois proficiency benchmarks and on three years of district academic data that populate the Vision 2026 dashboard and the Illinois school report card.

District staff framed the presentation around two linked measures: proficiency (the share of students who meet state standards on a single assessment) and growth (gain over time). “This is the fourth year of our strategic plan,” said Melissa, a district assessment staff member, adding that the presentation used the last three years of data to show progress under the district’s Vision 2026 goals.

Melissa explained that ISBE aligned performance levels across assessments and used ACT benchmarks as a ‘‘North Star’’ when setting new proficiency cut scores for grades K–11: "In ELA they landed at the proficiency for grade 11 being at an 18, and the proficiency for math being at a 19, and then they back mapped every grade level from there," she said. Staff warned the board that the state will not publish side‑by‑side results using the old and new cut scores, which complicates direct historical comparisons at the state level.

Using partner analyses, district staff converted the new cut scores to percentiles so the board could interpret what a proficiency percentage means relative to national norms. The district’s 2025 IAR proficiency estimates show variation by grade and subject, but Melissa said the district’s average student performance often…
