Related Services in Illinois IEPs: Speech Therapy, OT, and What the School Must Provide

Related services are the support services that make it possible for a child with disabilities to benefit from their special education program. Without them, even the best IEP goals fail. In Illinois, related services are legally required when the IEP team determines they're necessary — and "we don't have a therapist available right now" is never a legal reason to leave them out of the IEP.

What Counts as a Related Service Under Illinois Law

Federal IDEA and 23 Illinois Administrative Code Part 226 define related services broadly. The key criterion is function: the service must be necessary for the child to benefit from special education. Common related services include:

Speech-Language Pathology (Speech Therapy) — Identification and diagnosis of speech and language impairments; services to improve articulation, language comprehension, pragmatic communication, and fluency. One of the most frequently prescribed related services in Illinois IEPs, and one of the most frequently missed due to staffing shortages.

Occupational Therapy (OT) — Improves a student's ability to perform tasks required in the educational environment: handwriting, fine motor skills, sensory processing, organizational skills, and self-care skills like managing materials. OT in a school IEP is specifically educational OT, not medical OT — the goal is enabling the student to access their education.

Physical Therapy (PT) — Motor development, functional mobility, and access to school facilities.

Social Work Services — Individual or group counseling, family consultation, and crisis intervention that supports the student's social-emotional functioning in school.

Psychological Services — Psychological evaluation, consultation, and counseling services.

Transportation — If a student's disability requires specialized transportation to and from school or between schools, this is a related service the district must provide.

Assistive Technology — Devices and services that help a student access the curriculum, from text-to-speech software to communication devices.

Counseling Services — Rehabilitation counseling and parent counseling and training to help families support the child's IEP goals at home.

The Service Has to Be in the IEP — and Delivered

The IEP must specify the type of related service, its frequency, duration, location, and starting date. Vague IEP language like "speech therapy as needed" is insufficient and unenforceable. The IEP should say something like: "Direct speech-language therapy, 30 minutes twice per week, in a small group setting of no more than 3 students."

Once the IEP is signed, the district is legally obligated to implement it as written. A 2018 survey of Illinois special education staffing found that 50% of special education teachers and 42% of paraprofessionals were unavailable or insufficiently staffed — and the related service provider shortage has only worsened since. In CPS specifically, missed speech and OT minutes due to vacant positions were documented at scale.

The district's staffing problems are the district's problem to solve. Under IDEA and Part 226, the district cannot reduce or eliminate IEP-mandated services because they can't find a provider. They must find a solution — a contracted provider, a co-op provider, a telehealth provider — or pay compensatory services for what was missed.

How to Fight When Related Services Are Being Denied or Reduced

When services aren't in the IEP at all: If your child's IEP doesn't include speech therapy or OT and you believe they need it, request an evaluation. You can ask for a speech-language evaluation or OT evaluation specifically, in writing, at any time. The district must evaluate within 60 school days of your written consent.

When proposed service minutes are too low: If the IEP team proposes 30 minutes of speech weekly and you believe your child needs 60, you can disagree and withhold your signature. Request data from the evaluator about how the recommended minutes were determined. If the evaluator cannot cite research-based criteria or show how the minutes align with the severity of the deficit, that's a gap you can press on.

When services are being missed: Document every missed session. Email the case manager weekly: "Please confirm whether [child's name] received their scheduled speech therapy sessions this week." Save every response. After three or more consecutive missed sessions, put the principal and special education director on written notice citing your right to compensatory education for missed IEP services.

When services are cut at an IEP meeting: If the district proposes reducing speech from 60 minutes to 30 minutes and you disagree, you have the right to decline the proposed IEP. Request Prior Written Notice explaining the reasons for the reduction, the data they relied on, and any alternatives they considered. Prior Written Notice is a legal document — if the district's reasoning doesn't hold up, it becomes evidence.

The CPS Staffing Problem and What to Do About It

In Chicago Public Schools, speech therapist and OT vacancies are chronic and well-documented. Parents in CPS frequently discover their child hasn't received services for months because the school's position is vacant.

If you're a CPS parent and your child's related services are not being delivered, escalate past the school level to the ODLSS (Office of Diverse Learner Supports and Services). Document everything in writing — a verbal complaint to the school is not sufficient. The ODLSS escalation path, CPS contact hierarchy, and the specific letter language that gets results are covered in detail in the Illinois IEP & 504 Advocacy Playbook at /us/illinois/advocacy/.

The Difference Between Educational and Medical Services

One common district objection to OT and speech therapy is that the services are "medical" and therefore not the school's responsibility. This framing is legally incorrect. Under IDEA, related services must be provided by the school unless they require a physician — meaning school OT and school speech therapy are educational services, not medical ones, and the district pays for them.

Where this distinction matters: if the district tries to say your child's ABA therapy, feeding therapy, or intensive behavioral support is "medical" and therefore excluded, that requires careful analysis. ABA and behavior intervention services occupy a legal gray zone — whether the school must provide them depends on how the IEP team determines they relate to educational benefit. This is one of the harder fights, and it often requires an attorney for the due process stage.

The simpler cases — speech, OT, social work, counseling — are clearly educational related services. If your district is denying or cutting these, the path is clear: document, request Prior Written Notice, and escalate.
