Parents (and even educators) are often confused about the difference between a 504 plan and an IEP, and when each is appropriate. To choose between them, first the school and parents must find out whether the student has a disability as defined by statute. Then, they must decide what the school’s educational obligations are under each statute. The school must meet its obligations to provide a student with a disability the appropriate educational support. Finally, parents should know that their rights are different under each statute.
