Just ask the therapist - something like... Hey, I've noticed that you seem to only be at my home for 9 1/2 hours, but we had agreed that you would be here for 10 everyday. Is there something that I'm missing? It's really important to me that my child maximize early intervention hours because I know they payoff in the long run". You're very fortunate to be getting these services - I don't believe most people are able to get ABA at no/low cost. But, I'm sure that someone somewhere is paying for them, so you should have the same expectations as you would if you were paying the $100/hr out of pocket - make sure to hold them accountable.

If you've already confronted her, then she knows. If she's continued to not care, get someone new. Also let the company know why you'd like to get rid of her, get her lazy but in trouble.

I would find a new facility that provides ABA therapy. This sounds like it's on going and they don't seem to care about the importance of a child recurring as much ABA as possible. I think you would have better luck going to a privately owned facility.

A privately owned company sounds good to me :)

she is doing better but I think I will call agency this week. Thank you so much for the feedback, I greatly appreciate it.
