The admissions expert @prh47bridge has posted a thread on new school admissions arrangements.

I thought it would be worth explicitly mentioning one change on this board:
The requirement to give top priority to looked after and previously looked after children has now been extended to include children who were in state care outside England and were adopted from state care. State care in this instance includes being cared for by a religious organisation or some other care provider whose purpose is to benefit society. This change applies to 2022 admissions so existing published admission arrangements must be amended to comply.
