Hope all goes well - we were just asked to take in a book for DD to read and then were left to answer general questions. I also took in a few samples of school work and the SNC report.
I guess the Ed Psyche just needs to see the child in as 'natural' a way as possible to be able to see what issues there might be. Our session took a couple of hours - most of which I was out of the room - a newspaper and charged mobile phone is a must! I also took DD drinks and snacks as she was allowed a break.
I prepared my daughter by making it a bit of a day out - just her and me to see someone who could help with her hands (she is dyspraxic) and then we went for a 'forbidden' McDonalds afterwards.
