In a maneuver some state lawmakers call a "booby trap," the spending plan approved last week says Illinois can't appropriate money for schools unless a new funding formula also wins approval. It ties K-12 dollars to something known as the "evidence-based model."
Both political parties endorse this model, which is based on each district's demographics. The Democrats' version has passed the House and the Senate; they haven't sent it to Gov. Bruce Rauner, however, because he has promised to veto it.
