In this situation, she has already completed 1 full year of half day kindergarten with ABA therapy in the afternoons. She continues to do exceedingly well in ABA Therapy at the clinic. What she gets and learns at the clinic, FAR EXCEEDS the majority of what she gets from school. If we take her out of the clinic and send her to school for a full day, the amount of ABA therapy she will get every day will be cut in half or more. Not to mention the credentials of the 2 possible ABA therapists available at the school have not received any praise from any of the parents of children who have received ABA therapy from them. In every case, the parents had to seek additional ABA therapy outside of the school environment. So our motivation for using the School ABA Therapists in lieu of clinic she currently attends is not choice in her best interests.
I have never heard of a kindergarten readiness assessment, so I'm guessing that was not done in between preK and kindergarten. As for an IMO, I don't know what that is.
The school she attends is NEVER going to just "Offer" an extended school year for any special needs child. Like a 1:1, there will have to be a lot of documentation accumulated and used to argue for it.
As for the documentation I am using to ask for a 1:1, it comes from her teacher's assessments, the OT's evaluations, and other documentation collected by the school during the past year. Not to mention, our consistent ask for this since the end of her preK class (April 2022).
