Yes. The IEP must include all special education services, related services, and supplementary aids and services your child needs, and the school will provide. The IEP is a written commitment for the delivery of services to meet a student's educational needs.
The law requires these services to be based on peer-reviewed research "to the extent practicable."
Services in the IEP may include:
Special education services: specially designed instruction designed to meet your child's unique needs.
Related Services: services your child needs to benefit from special education (i.e., speech language therapy, occupation therapy, physical therapy, nursing services).
Supplementary aids and services: services and supports your child receives in general education classes and other settings so your child can be educated with children who are not disabled.
The IEP must include the projected date to begin services, and the frequency, location and duration of services. The model IEP form published by the U.S. Department of Education (2006) provides the format to record required information in the IEP.
