After age three, the process of education children with special needs changes a bit. Instead of an Individualized Family Service Plan (IFSP), children start using an Individualized Education Program (IEP). This program is designed to set goals for the child so that everyone can work together to meet them.
In addition to the new type of plan, this is usually the point that the local school district manages the child's education. You will probably have a new set of people to work with, and a new location to get acquainted with.
I remember how terrified I was to start this process. I was very worried that my son wouldn't get the services he needed. I did a lot of research, and unfortunately, it confirmed my fears. But when Tyler began his services there, he did very well.
There are a lot of good resources for parents at this point in the process. Some of the resources are for families who have had a very difficult time getting good services for their children. My advice is to go in with an open mind, and try to find the good in the situation. If problems arise, then seek the solution.
I am going to share the FamilyConnect.org resource again for this age group. I think their site is fantastic, and they can give much more in-depth and specific information than I have here.
