OP said it's an in-year transfer for a Y8 child. So I'm also a bit confused about how telling the EA about the selective test might jeopordise a place - perhaps the OP just needs some reassurance that the current school can't withdraw the place on the basis that the OP is looking at other schools elsewhere?
Oops, yes, just realised I'd missed that bit

Certainly in Essex, the mid-year transfer request form asks whether one has discussed the desired move with the child's current school (although tbh I can't remember whether it explains the relevance of this question).
Anyway, the child stays on roll at the current school until taken off it by the parent or, I assume, via some process when the new school tells the LEA that the child is now on roll there. When one of ours was moving, the Admissions lady at her old school said that when DD didn't turn up there on the notified first day at her new school, she would just ring the new school to check that she had actually turned up there.
