9th grade math teacher, I don't know how to help my student

So I have a student with dyscalculia and I don't really know how to help. No one has educated me on the topic, not at university and not at school. What can I do to help her? I have been reading this subreddit and the only thing I got clear is that she should always be able to use a calculator and that tests should be shorter. But aside from that, everybody seems helpless and says there is nothing anyone can do. So what can I do to make it easier for her?
