We are looking at a considerable financial commitment to move into the catchment area of our local sought-after state primary. Does anyone know how often catchment boundaries are changed, how can change them, and what process such changes go through? The houses we have seen so far are just within catchment and it's easy to fall outside just by ending up on the wrong side of a street. The school is over-subscribed and very few children - if any - get in from outside the catchment area.
