The advocate and/or attorney will handle it. I am glad she reached out to you. Knowledge is powerful and we need to be armed with it. I wish you and the other parent the best. Keep fighting for our special ones. They have no one else.

I've done this since my son was in Kindergarten. He is now entering 3rd grade. All I had to do was provide the school written notice of when he would be leaving and acknowledge that he may not meet academic goals because of the early departure. My was pulled about 40 minutes before the end of the school day twice a week. He arrived about 10 minutes late 1 day a week. It was vital that our son do this as these were the only appointments I could get with his therapists. He does OT, Speech and Vision therapy. I also had no desire take him after school even if I could. He had already spent a full day a school. He is still just a kid and after school appointments just make for too long a day.

Your IEP drives your assessments and your assessments drives your goals. If your goals are to have ABA and your assessment says he needs it let the district provide it on campus. Also check on district transportation. And one one aides. It's the Childs right.
Where are you located?

The school district should give all therapies at school thus the IEP. The Lanterman Act speech ape ot aba also check out your insurance

Just wanted to write an update to this post. I had asked the mom to consider talking directly to the director of special ed for the school district and she did. Happy to say he called the principal and told her all ASD kids are to be allowed to leave whenever necessary for therapies etc. Thank you all for your responses.
