More than half of special education teachers now use AI to help write IEPs, which means the language describing your child increasingly starts as machine output before a human edits it. A peer-reviewed study published in the Disability and Health Journal gives everyone on both sides of that table a reason to read the first draft closely.

Researchers from Special Olympics International and Oregon State University tested whether leading chat models describe people differently once a disability is mentioned. They do, and the difference runs the same direction across every model tested. Special Olympics announced the findings on June 16, and Disability Scoop brought the study to the disability community's attention this week.

What the Researchers Changed, and What They Kept the Same

The design is the part worth understanding, because it is what makes the finding hard to write off as a few unlucky outputs.

Karly Coffey, Gloria Krahn, John Hanley, and Jacob Neely built ten prompt stems describing ordinary situations: crossing a street, going to a store, playing a sport, working at a job. They asked GPT-4-Turbo to generate short stories from those stems, then repeated the process through four more models: OpenAI's GPT-4o, Meta's Llama-3-3-70B-Instruct, Anthropic's Claude-3-5-Sonnet, and Mistral-Large-2411.

Half the prompts included a descriptor for intellectual disability. The other half specified no diagnosis at all. Everything else stayed identical. That produced roughly 25,000 generated stories, which a separate instance of GPT-4-Turbo then read and coded against bias themes already documented in disability research.

The Five Patterns That Showed Up

The team grouped the differences into five categories, all of them familiar to anyone who has sat through a placement meeting.

Characters with intellectual disabilities were written as younger than comparable characters, even when the prompt gave no age. They were written as more dependent, relying on other people for help and for decisions. They were framed paternalistically, as needing supervision and extra care; Special Olympics reports that paternalistic tones appeared over 100 times more frequently in the disability story set. They were cast as inspirational for completing routine tasks, and the stories carried a negative or hesitant tone about including them at all.

"What our research shows is that bias doesn't have to be hateful to be harmful," said Nathan Cook, chief information and technology officer at Special Olympics. "It can be subtle, systematic, and scaled globally."

Why This Reaches Your Child's Paperwork

More than one in ten American workers now use a large language model to do their job, according to figures cited with the study. The people writing evaluation summaries, drafting goals, screening job applications, and answering benefit questions are inside that group.

A model that quietly ages a person down, removes their decision-making, and adds a supervisor is producing exactly the language that weakens an IEP. Present levels written that way describe a child who needs monitoring rather than one who needs instruction. Goals written that way set a ceiling. Transition plans written that way skip self-determination and land on supported everything.

None of this requires anyone to hold a prejudiced view. The draft arrives already tilted, and editing a draft is a weaker act than writing one.

How to Read an AI-Assisted Draft

Ask, first, whether any part of the document was generated with an AI tool. Districts are not required to volunteer that, and asking is reasonable.

Then read the draft against the five patterns. Check the stated age and grade language against your child's actual age. Check who makes decisions in every sentence that describes a routine. Check whether accomplishments are described as achievements or as inspiration. Check whether the words "supervision," "assistance," and "support" appear where "instruction" and "practice" belong.

Where the language flattens your child into a category, replace it with the specifics you have: what they did last Tuesday, how long they sustained it, what prompt level they needed. Documenting a disability without oversharing is the same skill applied in the other direction, and the full IEP advocacy walkthrough covers how to get a revision on the record rather than in conversation.

Special Olympics is asking AI developers to acknowledge the bias, invest in mitigation research, and bring people with intellectual disabilities into design work directly, which is a multi-year project at best. The document with your child's name on it is due at the next meeting, and every Parent Training and Information Center offers free help reviewing the draft before you sign it.
