I don't have expertise in this but, just a thought since you are contemplating the test. How was your child after the test? Did she give any reactions?
The reason I bring this up is when DS had IQ testing done, the school psychologists did not prepare him for the test and he was upset after it. MY DS does not usually have any test anxiety and was already familiar with the tester. This makes me think if someone was in a similar situation they may get untrue results. But this may not be your situation.
