Oh dear, scarlett, that's a shame. it can be a very difficult time leaving primary and moving to secondary. I'm surprised the new school is making them do tests, seems very strange. Usually these are done in September once they've started for real, and taster days are offered with fun activities, rather than learning to get them acclimatised, so to speak.
Does he know anyone going to the new school? If so, perhaps you can arrange for them to get together over the summer, to reinforce some friendships before the new term starts? My youngest went to his school with one girl from his school and they were put in different forms so it was all very daunting for him, as he didn't really like/know well the girl anyway, and his taster day was cancelled due to swine flu I think
, so come the first day he was absolutely terrified. However, we just kept trying to put a positive slant on the whole thing, and jollying him along, and it didn't take too long to settle down. His school is also very strict on the children, and that was also quite hard for him at the beginning, as he too had been used to a pretty small primary school.
I do like the idea of the tree costume, wish I had thought of that
