IEP and 504 are two different programs that are established by governments to achieve proper education for the disable people in the society. The IEP, which simply stands for Individualized Educational Plan, is a program designed by the government to help children with disabilities to achieve their educational goal. The real aim of this program is to help children with disabilities to successfully attend the normal elementary and secondary school, and that help should be provided for them when needed.
The body in charge of monitoring this program is the IDEA (that is Individual with Disabilities Education Act). On the other hand, the 504 program, which is established by the government also, focuses on ensuring that disabled people benefit from any government funded programs. In addition, they also ensure the allowance of disabled people in activities such as elementary, secondary, and tertiary education. This program also assists them in acquisition of necessary properties such as home instructions, wheelchair ramps, tape recorder for notes, and etc.
