Hi,
I'm sorry to hear you're going through this. I can't imagine this rising to the level of discrimination as she does have a disability that does in fact not allow her to keep up with the rest of the class. As a private institution, they are likely in their right to suggest she go elsewhere.
That being said, to answer your question specifically, you will likely simply need an "advocate." An advocate is an attorney that will simply be an ally for you and your daughter and help you attempt to get what you need. You will very unlikely find an attorney to take this case contingent (meaning you don't pay unless the attorney gets you something) or pro bono (meaning, for free or for charity) which means you may end up having to pay an advocate to fight on your behalf. Specifically what you need is an attorney in a "general practice", often found in store fronts or by word of mouth from community members, etc.
Of course nothing I said should stop you from trying to get an attorney to take your cases contingent or pro bono.
Best of luck to you and your daughter!
