Since you are already doing ABA and would continue to do so (at least 10hrs/week), I would consider PRT to augment other skills areas that ABA doesn't do a good job focusing on - and what is important about PRT is really the parent training, so the therapy techniques can be continued during off time which is more important long-term. I am assuming you can do 20 hrs ABA once PRT is over. We did a bit of pivotal response ourselves which was effective, and then switched over to Verbal Behavior/ABA. Our son was highly verbal and VB/ABA worked better for us due to hyperactivity/escape behavior. Now that he is calmer with longer attention span, I believe other therapies such as Floortime, RDI, and PRT are more effective. We still do maintenance ABA to focus on specific weaknesses e.g. fine motor skills.

I wouldn't let your insurance ABA services go, while you still can do both , ABA therapies is going to be one if your primary therapies for a long time, we do get it trough our health insurance 20 hours, and they will provide it as long as we need it , so I wouldn't loose that great benefit, good luck!!!
