What Is the Primary Purpose of an Individualized Education Program

What is the primary purpose of an Individualized Education Program (IEP) ?

A) To place the special needs child in a special class or school in order not to impede either the teacher's established lesson plan or the progress of children who do not require individual attention.
B) To place the special needs child in whatever special class or school is most appropriate for that child's level of functioning.
C) To combine regular classes and special classes in a way that would enable special needs children to participate in regular school activities-both academic and non-academic-and interact with their non-special education classmates.
D) To greatly reduce the need for special schools and classes by structuring an individualized instruction plan that would work entirely in a regular classroom setting.
