One issue we came up against that I don't think has been mentioned here is the longevity of the waiting list.
DD did not get into the same school as DS, as we were just outside catchment, but we were advised that she was 2nd on the waiting list. Since I knew that one child in that year was actually going to a private school (although the parents decided to keep the place at the primary school open until their child was 5 just in case they didn't like the private school - agghhh! but that's another story), I was crossing my fingers that we might stand a chance at some point during the year that she would be able to transfer to her brother's school, provided nobody else her age moved into the catchment area.
What we didn't know, was that the waiting list only lasted until Christmas. The LA could not explain to us why, other than that it was inconvenient for their office staff to keep it open - although they did not say how.
What we ALSO did not know, was that you can't apply to the same school more than once in one year.
Therefore, if a place became unexpectedly available in January, we would no longer be on the waiting list for that space and would not be allowed to apply for that place until the following school year. However, anybody else no matter how far away they lived, no matter whether they had a sibling or not, WOULD be able to apply provided they had not already done so that school year.
Closing down the waiting list just does not make sense to me. The waiting list was moveable - a catchment area child would have gone straight to the top of the waiting list, so DD would not have denied a 'more local' child a place.
Perhaps MNHQ could suggest a waiting list should last the whole school year? Also, if a child has accepted a private school place, a state school place should not be held open for them on the basis but that they should reapply if they decide to move back to the state system
