That's really frustrating. Try different test when he turns 6, you may also try an achievement test, that's usually a language school can understand.
I believe the psychologist can substitute one subtest and perhaps she could have used something which doesn't require fine motor skills. It was an IQ test, not OT test after all. She could have also pushed him a little bit to give her answers when she thought he knew them. I think that's the most frustrating part, the question he could have answered but didn't.
Her opinions about school, friends and such are completely off. She should at the very least understand that there are situation when testing 5 year old is a good idea.
