Kimber Wilkerson, a professor of special education at the University of Wisconsin-Madison, said 504 Plans tend to be less formal than an IEP. They usually represent a collaboration between parents and school leaders to figure out what the student needs to be successful at school. For a student with ADHD, that might be extra time to take tests. For a student with Type 1 diabetes, it could be access to snacks during the day.
In reality, Wilkerson said, many teachers would be willing to extend those kinds of accommodations to students who needed them, even without documentation. But the advantage of a 504 Plan is that families don’t have to re-explain their situation to a new teacher every time the student advances to a new grade, she said. That’s especially important when students reach middle and high school, where they have several teachers throughout the day instead of just one.
