I've never heard of testing done that way. It sounds to me as though she is relying more on clinical observation than on standardized tests. I'd prefer someone who used both.

I think you would be reasonable to ask what her game plan is, and on what her diagnosis will be based.

Yes, our insurance covers all diagnostic testing of this kind; but they surely wouldn't cover an open-ended process like the one your psych is using.
