District 303 staff propose cohort-based student achievement report, ‘Opportunity Scale’ to tie ACT/IAR data to student pathways

District 303 administrators presented a package of changes to the district’s Student Achievement Report on Monday, Sept. 22, asking the Learning & Teaching Committee for feedback on cohort tracking, deeper disaggregation and a new “Opportunity Scale” that maps ACT score ranges to postsecondary and career pathways. The administration said it plans to return a fuller Student Achievement Report (SAR) to the committee in November for board review.

The proposal centers on three reporting shifts: tracking cohorts over time rather than relying solely on year‑to‑year cross‑sectional comparisons; comparing district cohorts to weighted benchmark and aspirational districts and the state; and adding a color‑coded “Opportunity Scale” that connects ACT score bands with the college and career opportunities historically reached by District 303 graduates. “We are not basing our goals or performance targets on the state,” the presenter said, “but we’re planning on using some state performance levels to give us clues.”

Administrators said the state has changed unified performance levels for assessments (IAR, ACT and the Illinois science assessment) and that the changes produce a non‑linear “wave” across grade levels — meaning proficiency is not equally difficult from grade to grade. The presenter used national/state visuals to illustrate that the relative difficulty of meeting proficiency can shift between grades and between math and ELA, and said the district will use that wave as a predictive lens when interpreting its own D303 cohort data rather than treating the state benchmarks as district targets.

Why it matters: committee members and administrators said the proposed report is intended to make data more actionable for principals and teachers, not just a one‑night board presentation. Administration described a plan for a district data team that would disaggregate state assessment data for each building, feed it into the building continuous improvement process and…
