Accommodations are changes that remove barriers and provide your child with equal access to learning. Accommodations don’t change what your child is learning. Rather, they change how your child is learning.
The Individualized Education Program, often called the IEP, is a legal document under United States law that is developed for each public school child in the U.S. who needs special education. It is created through a team of the child's parent and district personnel who are knowledgeable about the child's needs.
Modifications are changes to what your child is taught or expected to do in school. Modifications aren't the same as accommodations, which are changes to how your child learns. Only students with an IEP or a 504 plan can have modifications.
