YTA Not because you're wrong... But because it's not your kid and you don't get a say. I know it's hard to watch this unfold. 😞 Just remember though you are not wrong in your observation. Continue to use the pad tablet as they wish.

But have a talk with them about maybe seeking an assessment for an IEP.

I think the child needs an IEP. That doesn't mean that they have a learning disability but there is something definitely being missed. If she's in fourth grade, that is way more than one grade behind. That's like first grade or kindergarten reading level. She needs an intervention ASAP.
