Illinois Special Education Under Strain
What the CPS Cost Surge and ISBE’s AI Warning Mean for Families
Two recent developments in Illinois special education tell a connected story. Chicago Public Schools is spending nearly twice what it did in 2019 on special education, driven by a surge in students who need services. At the same time, the Illinois State Board of Education has issued a pointed warning about a rise in complaints, mediation requests, and due process filings that appear to be AI-generated — and often incomplete. Together, these two trends show a system under real pressure, with families caught in the middle.
CPS’s Special Education Numbers Are Striking
As of this spring, nearly 83,000 CPS students qualify for either an IEP or a 504 plan — 26% of total enrollment, up from 20% in 2019. The number of CPS students with autism has doubled since 2019 alone.
The financial picture tracks the enrollment picture. CPS spent $1.8 billion on special education in 2026, almost double what it spent in 2019, even as the district’s overall enrollment dropped by 45,000 students. Much of that spending has gone toward staff: CPS added roughly 9,000 employees over the past seven years, primarily teachers, aides, social workers, psychologists, and therapists needed to meet legally binding IEP obligations.
At the school level, the shift can be dramatic. At one West Side elementary school, the share of students with disabilities tripled over eight years, and the special education staff grew from five people to thirty-six. Principals in lower-income neighborhoods report that filling vacancies for special education teachers and aides remains the persistent bottleneck.
Why the Numbers Are Climbing
Experts point to several converging factors rather than one single cause. Pediatricians and parents are more attuned to early developmental signs, leading to earlier autism diagnoses, particularly in preschool, kindergarten, and the early elementary grades. Some of what looks like a genuine increase is also better identification of disabilities that, in past decades, went undiagnosed or unaddressed. Research increasingly supports getting kids identified and served earlier, though doing so is expensive.
Underneath all of this is a persistent funding shortfall. Illinois’ state funding formula leaves roughly two-thirds of school districts below the state’s own adequacy target, a gap experts say will take at least another decade to close at current funding rates. Federal funding is even further behind: it covers only about 10.5% of the average per-student cost of special education, far short of the 40% Congress promised when the original law was passed in 1975. CPS leadership has publicly pressed Governor Pritzker for a special legislative session on school funding, so far without success.
ISBE’s Warning About AI-Generated Filings
Separately, ISBE has flagged a concerning pattern in its own dispute resolution process. The agency states that it has “observed a significant increase in complaints, mediation requests, and due process requests that appear to be AI generated.” According to ISBE, these submissions “often fail to include facts to support a potential violation of special education requirements or provision of a free appropriate public education (FAPE).”
ISBE isn’t telling parents to avoid AI tools altogether, but the agency is clear that AI shouldn’t be the sole resource for drafting a legal filing. Its guidance warns that AI “is not a reliable tool for ensuring legal accuracy or determining whether your complaint or due process request meets necessary requirements,” and that incomplete or unclear filings may be deemed insufficient — triggering a resubmission and delaying the process for a family that may already be waiting on services. ISBE also flags a privacy concern: information entered into an AI tool may not remain confidential.
What This Means for Families
These two trends point in the same direction: the system serving Illinois students with disabilities is stretched, and the margin for error in navigating it is shrinking. A few practical takeaways follow from that.
Rising need is outpacing available capacity. With CPS enrollment in special education growing faster than staffing and funding can comfortably absorb, families may encounter longer waits, staffing turnover, or services that don’t fully match what the IEP calls for. Documenting specific gaps — what the IEP requires versus what’s actually being delivered — matters more than ever if a dispute becomes necessary.
AI can help you understand your rights, but it isn’t a substitute for legal guidance on a filing. Procedural safeguards notices and IEP paperwork are dense, and using an AI tool to get oriented is reasonable. But turning that understanding into a state complaint or due process request that will actually hold up requires attention to specific factual and procedural requirements that generic AI tools aren’t equipped to verify.
Local advocacy and early resolution still matter. ISBE’s own guidance points families first toward direct communication with school staff and IEP teams, and toward voluntary tools like state-sponsored mediation and IEP facilitation, before escalating to a formal complaint or hearing. Given the added burden a poorly drafted filing can create, getting it right the first time — with professional input if needed — is worth the extra step.
Bottom Line
Illinois families are navigating a system that is serving more students with more complex needs than it did even a few years ago, without a matching increase in state and federal funding. If your child’s IEP isn’t being followed, or you’re considering a formal complaint or due process request, it’s worth talking to an attorney before filing — both to make sure the filing is complete and to understand what options, including informal resolution, might resolve the issue faster.
