I know i've posted a few time on this topic, to people's annoyance, but we had an update from the school yesterday (their appeal response has been sent to us).
It includes result of our DS CAT4 assessment data and his aptitude test results.
In the appeal we are arguing that due to tonsilitis (as diagnosed by a doctor a day) he wasn't fairly/ correctly banded.
His primary school has been us a CAT4 scaled score of 108, his CAT4 assessment was 98. So there is a big variation. I guess our argument here is he was incorrectly banded, and in not being offered a place was disadvantage by this.
On the drama aptitude test, he scored 24/25 - but only 4 children got a drama place, they all got 25/25. But on the other offered aptitude test - dance, sport, music, children with as low as 88% scoring were successful. I guess my argument here is he was unfortunate to not be selected with a 96% score.
