Illinois Rep. Mussman’s school funding adjustment bill passes House and Senate

Passed bill authored by State Rep. Michelle Mussman aims to end certain school funding adjustments, define public day school requirements, and revise teacher bonus distribution following approval in both chambers, according to the Illinois General Assembly.

In the House, 66 Democrats and 33 Republicans voted in favor of the bill.

Meanwhile, in the Senate, 35 Democrats and 19 Republicans voted in favor of the bill.

Mussman introduced the bill in the Illinois House on Feb. 6, 2026 during the 104th session.

The legislation, known as HB5551, was passed on May 28, 2026 during the general assembly session 104.

According to the Illinois General Assembly site, the legislature summarized the bill’s official text as follows: “Amends the School Code. Provides that certain provisions concerning the recomputation and adjustment of a school district claim for general State aid or evidence-based funding shall end with Fiscal Year 2026. Provides that when a child from an orphanage, foster family home, other State agency, children’s home, or State residential unit eligible for special education services is placed in a separate public day school, that school shall meet the programmatic requirements and regulations for separate public day schools. Provides that any funds appropriated for the Illinois Teaching Excellence Program must be used, among other purposes, for indirect costs necessary for Program operation. Provides that an annual retention bonus of up to $4,000 (rather than $4,000) per year for 2 consecutive years shall be awarded to National Board certified teachers employed in hard-to-staff schools and such funds must be disbursed equally on an annual basis among all qualified educators (rather than on a first-come, first-served basis). Makes other changes. Effective immediately.”

The following is our breakdown, based on the actual bill text, and may include interpretation to clarify its provisions.

In essence, this bill ends, after fiscal 2026, the ability to recompute and adjust school district general state aid and evidence-based funding claims based on certain property tax assessment changes, while capping related statewide adjustments at $25 million a year through fiscal 2026. It requires that, beginning with the 2026-27 school year, separate public day schools serving eligible children from orphanages, foster homes, state agencies or residential units meet statutory definitions and program rules. It also allows Illinois Teaching Excellence Program appropriations to cover indirect operating costs and changes National Board teacher retention bonuses in hard-to-staff schools so awards of up to $4,000 a year for two years are distributed equally among all qualified educators. The bill takes effect immediately.

The bill was sponsored by Rep. Diane Blair-Sherlock (Democrat-46th District), Sen. Christopher Belt (Democrat-57th District), and Rep. Katie Stuart (Democrat-112th District), along with four other sponsors.

Bills in Illinois follow a multi-step legislative process, beginning with introduction in either the House or Senate, followed by committee review, floor debates, and votes in both chambers before reaching the governor for approval or veto. The General Assembly operates on a biennial schedule, and while typically thousands of bills are introduced each session, only a fraction successfully pass through the process to become law.
