Funding

How Illinois funds schools

Illinois distributes most state K-12 aid through Evidence-Based Funding (EBF) (2017): the state sets each district’s research-based Adequacy Target, compares its local resources to that target, and sorts districts into four tiers, steering most new money to the districts furthest below adequacy, while a Base Funding Minimum ensures no district receives less than the prior year. The law targets at least $350 million in new EBF funding each year.

District-level per-pupil spending and the local/state/federal revenue split for Wilmington CUSD 209U are published in the federal school-finance files — see the full-data links below for the current figures.

Accountability

Report card & state results

Illinois publishes the Illinois Report Card each year, reporting achievement and growth in English language arts and math, graduation, attendance, finances and climate, and assigns each school a summative designation (Exemplary, Commendable, Targeted or Comprehensive Support).
