The noise and disruption is just an inconvenience. What really matters is, is she learning at her own preferred pace and being intellectually challenged. If not, you need to consider alternatives.
I disagree with the first part of this. Noise and disruption is more than just "an inconvenience" for some of us. Even if the material is at the perfect level for the learner, it can be nigh well impossible to focus on it if your neighbor is chattering, some kid in the back is yelling, or the teacher frequently stops to reprimand someone.
As an adult, I wouldn't tolerate noise and disruption in my classes, so why should a child be asked to get used to it?
