I just wanted to give you my input, as an autistic person who has heard a lot about ABA, and some of the long-term effects of ABA.
Your goals should not be to render a child to be indistinguishable from his/her peers. This is impossible, as there is no set mold for human beings.
You also should not be aiming to make a child automatically obedient, as this may damage the long-term ability to make decisions for his/her self and be able to avoid potentially abusive situations.
You goal should be to help people in the community, the family and the child to understand the strengths and weaknesses of the child, and help the child to develop skills to overcome disabilities and develop life skills in order to become as independent as possible. The goal is like being a parent, to raise a child to, ultimately, not need you anymore.
The difference is that there are various degrees of independence, and some have different potentials, but what really matters is being able to live freely, interacting as one wishes, and living happily.
this is my opinion as an autistic.
