I have an 8 year old autistic angel, who is in a special needs class during the day. He has a fantastic teacher and aides, very helpful but he now gets ABA therapy and WOW that has really made a difference. It took awhile to get funded but oh so worthwhile. He is becoming a little conversational when you try to chat with him ( and he is in the mood).

If your child does not already have an IEP, which they may not because she is so high-functioning, you need to request an IEP Team Meeting to put together a new IEP with this diagnosis added. Every LEA has an affiliated Intermediate Unit which has an Autism Support Team. Get them involved. Seek out the professional advice of a Licensed Psychologist to add to the IEP, including a Behavior Support Plan. How old is your daughter?

Here is another link to hopefully provide you with the information you need to determine whether your child is entitled to an IEP under IDEA or a 504 Plan http://www.education.nh.gov/instruction/school_...

Not all students who have disabilities require specialized instruction. For students with disabilities who do require specialized instruction, the Individuals with Disabilities Education Act (IDEA) controls the procedural requirements, and an IEP is developed. The IDEA process is more involved than that of Section 504 of the Rehabilitation Act and requires documentation of measurable growth. For students with disabilities who do not require specialized instruction but need the assurance that they will receive equal access to public education and services, a document is created to outline their specific accessibility requirements. Students with 504 Plans do not require specialized instruction, but, like the IEP, a 504 Plan should be updated annually to ensure that the student is receiving the most effective accommodations for his/her specific circumstances.

I was in your shoes when my son was diagnosed with Asperger's Syndrome. I was like thanks for the diagnosis now what? Well, I did my own research on the net, called my insurance company to find a therapist and a psychologist, and went on from there. Your insurance company should be able to find a therapist and psychologist in your plan. Sometimes the child needs meds and sometimes they do not.
My son, for example, has and underlying diagnosis of ADHD, so he primarily takes medication so he can calm down, this is because he cannot calm himself on his own. He has calmed more with age as well.
If you are one of those parents who are strongly against medicated your child, that is fine too, just find some type of therapy to help him/her out! You can also Google autism therapist in your home town. Sometimes occupational therapy will help more than any other therapy, which is widely used for autistic kids! I hope this helps you out!
