504 Plan

504 plans are formal plans that schools develop to give kids with disabilities the support they need. That plan covers any condition that limits daily activities in a major way. These plans prevent discrimination and they protect the rights of kids with disabilities in school. They’re covered under Section 504 of the Rehabilitation Act which is a civil rights law. 504 plans aren’t part of special education, so they’re different from IEPs. 504 plans and IEPs are covered by different laws and work in different ways. But the end goal is the same: to help students thrive in school.
