Good post, Star.
I can't really add much to that.
We are an ABA family. We have been 'doing' ABA in various forms and settings (home programme, 2 different schools) for 8 years now. It is the only way dd1 learns (and yes, we have tested this - the years she spent in non-ABA settings and environments were hellish to say the least, and she still has issues which stem from those times. There are no issues which have been created in the same way from her time doing ABA, with different consultants and tutors - couldn't begin to say how many. Oh hang on, there is one issue she has, with an ex tutor. It runs quite deep, and we haven't been able to get to the bottom of it. I expect a personality clash, as I cannot see how anything is supposed to have happened, but I keep listening when dd1 talks about the tutor concerned. School,were very proactive when they realised the extent of the issue).
The only time I have ever seen dd1 'robotic' or 'trained' (more than any child is 'trained' ie toilet training and general - realistic - expectations) is when she was in a TEACCH setting. She was virtually catatonic she was closing down so much, and despite not ever having a silent moment during her out of school hours, she was practically mute when there. The school did nothing to alleviate her stress, just expected her to fit in (this was a highly respected ASD setting), and actually ended up telling us that they were pretty sure dd1 would never learn anything in a school setting. Dd1 was 5 at the time. A whole life written off, just like that (if the LA had had their way, dd1 would have continued at that school, then their follow-on setting. No bloody way. She never returned after the meeting when we were told that).
In contrast, under ABA, dd1 has flourished, and moved so far from the scared, confused, blank faced child she was at that school. She can read and write, manage basic money, and is beginning to master living skills such as making her own lunch. More importantly, she has been taught how to play, and relax enough to enjoy herself. She is now confident enough to talk to other people, despite her severe language disorder. She has a range of playskills, and participates in sports and clubs. She recently competed in a competition for one of her sports, and got through to the national finals.
Most of her school day is taken up with learning the 'funner' aspects of life. She has academic targets, sure, because she is capable of them, but her IEP also includes (about half of it, I'd say) targets on playing (on her own or with peers - her choice), and sports (chosen by her) as well as various SALT groups and OT etc.
She is far better served, at her ABA school, than dd2 (also on the spectrum) whose needs are mostly overlooked and sidelined at her mainstream school. There are teachers at dd2's school who I mentally recoil from the thought of leaving her with (not through physical safety fears, but due to general,ignorance about ASD, and what will be said, out of ifs orange, to dd2) but none at dd1's school, as they all are more than happy to put the child first (more than can be said for dd2's school).
