The bill amends 20 U.S.C. §1411(i) to convert most Part B funding under the Individuals with Disabilities Education Act from discretionary grants to a schedule of mandatory appropriations tied to a national per‑pupil spending benchmark and actual counts of children with disabilities. It establishes year-by-year dollar floors and percentage targets that rise from FY2026 levels through FY2035, when funding reaches 40% of the product of the national average per‑pupil expenditure and the number of eligible children (and remains at that level thereafter).
That change shifts material responsibility for special education financing toward the federal government and creates predictable, escalating outlays. The bill also explicitly appropriates the listed amounts (not merely authorizes them) and requires that the new spending comply with cut‑as‑you‑go (PAYGO) budget rules, which forces Congress to identify offsets or revenue to cover the increase in mandatory spending.
At a Glance
What It Does
The bill replaces the current discretionary funding approach for most of IDEA Part B with mandatory annual appropriations that are either a fixed dollar floor or a percentage of a formula amount (the number of children with disabilities times the national average per‑pupil expenditure), whichever is greater. The percentages and dollar floors increase in scheduled steps through FY2035, when the statutory floor equals 40% of the formula product for FY2035 and each subsequent year.
Who It Affects
State education agencies and local education agencies that receive Part B grants; the Department of Education, which must distribute larger mandatory grants; federal budget and appropriations processes because these become mandatory outlays; and ultimately students with disabilities and their families through expanded federal funding.
Why It Matters
The bill converts a longstanding, unmet federal target for special education support into binding mandatory appropriations, creating multi‑billion dollar new federal obligations. That alters the fiscal relationship between federal and state governments and imposes practical distribution, administrative, and budgetary consequences for agencies and Congress.

What This Bill Actually Does
This bill rewrites the funding mechanics for Part B of IDEA. Instead of relying on annual discretionary appropriations that have historically fallen short of federal targets, it spells out mandatory appropriations in statute for a series of fiscal years.
For each year the statute gives both a fixed dollar amount and a percentage of a formula product, then instructs that the greater of those two figures will apply. The schedule steps up gradually from FY2026 through FY2035, where the statute locks in a permanent floor equal to 40% of the computed formula product for FY2035 and beyond.
The formula product the bill uses to define the pool of funds is the number of children with disabilities who received special education in the last completed school year (with ages 3–5 included only for states eligible under section 619, and ages 6–21 included nationwide) multiplied by the national average per‑pupil expenditure in public elementary and secondary schools. That ties federal Part B funding directly to two measurable inputs: an annual count of served children and a national per‑pupil spending benchmark.Practically, the statute both authorizes and appropriates the listed sums for each year — the text uses language that makes those amounts available on specified obligation dates (generally July 1 of the fiscal year) and remain available through the following September 30.
By making funding mandatory and explicitly appropriated in statute, the bill reduces the annual discretion of Congress over these grants but also creates recurring mandatory outlays that must be paid for under current budget rules.The bill also contains a short offsets clause requiring the increases to be handled consistent with cut‑as‑you‑go (PAYGO) rules. In operational terms that means the Congressional Budget Office and the Budget Committees will treat the added mandatory spending as requiring offsets or revenue to avoid adding to PAYGO scorecards, and the Department of Education must adapt its grant distribution systems to the new mandatory schedule and enlarged grant amounts.
The Five Things You Need to Know
The statute sets a step‑up schedule of explicit dollar amounts and percentage floors for FY2026–FY2034 and makes FY2035 the first year in which the floor is 40% of the formula product, with that 40% level continuing each subsequent year.
For the formula, the bill multiplies the count of children with disabilities (based on the last school year that concluded before the fiscal year) by the United States average per‑pupil expenditure; ages 3–5 are included only for states eligible under section 619.
The text both authorizes and 'hereby appropriates' the listed amounts for each year and states the funds become available for obligation on July 1 of the fiscal year and remain available through September 30 of the following year.
Section 2 excludes section 619 from the mandatory funding changes — the amendment applies to Part B other than section 619 (the preschool grants provision) — even though the formula's child count includes preschool ages only for eligible states.
Section 3 requires that the new appropriations be handled consistent with cut‑as‑you‑go (PAYGO) requirements, meaning the increases must be offset under current budget enforcement rules.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Names the measure the 'IDEA Full Funding Act.' This is a conventional short‑title clause with no operational effect beyond citation convenience.
Mandatory funding schedule and appropriations language
Replaces the existing discretionary authorization language with a multi‑year schedule that lists, for each fiscal year, a fixed dollar amount and a percentage of a separately computed product, and directs that the greater amount applies. The text uses the phrase 'there are hereby appropriated' for each listed figure, which in practice moves these sums into mandatory statutory appropriations rather than mere authorizations. For practitioners, that changes how grants are budgeted and obligates the federal government to deliver those sums unless later amended by Congress.
Formula for determining the benchmark amount
Defines the 'amount determined under paragraph (2)' as the product of (A) the total number of children with disabilities who received services during the last completed school year (with preschool ages included only for states eligible under section 619) and (B) the national average per‑pupil expenditure in public elementary and secondary schools. The choice of a national per‑pupil average as the multiplier standardizes the benchmark across states but decouples the federal calculation from state‑level cost differences.
When funds become available for obligation and duration
For each fiscal year the statute specifies that the appropriated amount 'shall become available for obligation' on July 1 of the fiscal year and 'shall remain available through September 30' of the following fiscal year (with the initial years following the same pattern). That timing aligns federal availability with the school calendar in a predictable way, but it also prescribes the administrative schedule for states and the Department of Education to obligate and spend the funds.
Offsets and PAYGO treatment
Directs that the newly appropriated amounts 'shall be expended consistent with cut‑as‑you‑go requirements.' This is a procedural instruction that flags the increased mandatory spending for PAYGO enforcement and implies Congress must identify offsets or other statutory adjustments to avoid adding to PAYGO obligations; it does not itself specify which programs or revenues will be cut or raised.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Children with disabilities and their families — the statute guarantees a rising federal funding floor tied to the number of served children and a national spending benchmark, which should expand available federal dollars for special education services.
- State education agencies in low‑capacity or high‑need states — predictable, mandatory federal funds reduce reliance on variable discretionary appropriations and can relieve some state and local fiscal pressure, especially in districts with higher special education costs.
- Local education agencies (school districts) with high special education populations — larger federal grant inflows can offset local spending and potentially expand services, staffing, or program quality for eligible students.
- Special education service providers and contractors — increased and stable federal funding can support sustainable demand for related services, assessments, and therapies contracted by districts.
Who Bears the Cost
- The federal budget (Treasury) — converting these sums into mandatory appropriations creates large, permanent outlays that increase federal fiscal exposure unless offsets are enacted.
- Other federal programs or mandatory spending categories — because the bill invokes PAYGO, Congress will need to identify cuts or revenue increases, which could reduce funding elsewhere or require new revenue sources.
- Congressional appropriations and budget offices — implementing and scoring the mandatory schedule increases administrative burden on the CBO, Budget Committees, and appropriations staff, who must calculate offsets and incorporate the new mandatory baseline.
- The Department of Education — the agency must scale grant distribution systems, monitoring, and compliance oversight to handle larger, formula‑driven mandatory grants, which may require upfront administrative resources.
Key Issues
The Core Tension
The central dilemma is between guaranteeing significantly greater, predictable federal support for special education (advancing equity and program stability) and the fiscal and distributional consequences of locking in large mandatory outlays (which require offsets that will reduce resources elsewhere or raise revenue), all while using a national per‑pupil benchmark that may not reflect local cost realities.
The bill ties federal Part B funding to a single national per‑pupil average rather than state‑ or district‑level costs. That choice simplifies the calculation but raises questions about geographic cost variance: a dollar tied to the national average may under‑compensate high‑cost states or overcompensate low‑cost ones, and it does not directly account for the 'excess costs' framework that often underpins special education funding discussions.
The statute provides both fixed dollar floors and percentage floors (whichever is greater) for multiple years; those dual floors create complexity in forecasting federal outlays because appropriated dollar amounts could diverge materially from the percentage of the formula product in different years.
Mandating appropriations and invoking PAYGO shifts the political and fiscal tradeoffs to Congress: the statute ensures larger federal contributions for special education but forces offsets under current budget rules. The bill does not specify offset sources, leaving open whether Congress will cut other programs, tap mandatory entitlement savings, or raise revenue.
Operationally, the Department of Education will need to reconcile the statutory obligation language with existing grant regulations and state allocation formulas, and states will need to map the new federal inflows to existing maintenance‑of‑effort requirements and local budgeting practices. Finally, excluding section 619 from the substantive change while still counting preschool children in the formula for eligible states creates a hybrid that could generate implementation questions about eligibility, pass‑throughs, and preschool grant administration.
