Let her know that stuttering is perfectly ok and doesn’t make her less of a person. I also suggest not interrupting her if she’s having a bit of trouble, and especially not to say “take a deep breath” or “just spit it out already!” If my mom hadn’t said those things I might not be as self conscious as I am now. And school therapy sucked for me. I don’t know where you guys are from or how she’s receiving therapy but don’t do it through school. I did it when I was in elementary school, and some of high school. They typically only meet once a month if that and that’s not enough time to get any kind of real assistance. Since she’s saying it’s not helping, I’d suggest visiting someone else. But keep in mind, there’s no cure for stuttering so I’d steer her towards embracing it,which leads back to my first paragraph. For presentations and other extremely difficult tasks I used to practice speaking in front of my stuffed animals. It’s a little weird but I wasn’t so nervous around them and that usually helped when it was time to do the real thing. Key word usually. I kinda rambled a bit but my main point is to tell her that it’s ok to stutter. Don’t apologize or anything for it. That’s a habit I’m trying to break after almost 10 years (been stuttering my whole life, started apologizing for it around 14) and it’s not easy bc I’m still not comfortable with my stuttering. But I believe your daughter will have a better chance because she has you, someone who cares and wants to help. Good luck op. Hope this helps.
