DD is summer born and due to start school Sept 2017 - she will have only just turned 4. We live on the edge of a fairly deprived area in a big city. There are two local primary schools, one that is over subscribed and rated outstanding by ofsted and another that is under subscribed, in a middle of an estate with a bad reputation and rated average by ofsted. We live well within the catchment area for both schools but the better school is tiny and at least 50% of the places go to siblings. WIBU to delay her start to 2018 if she does not get a place at our preferred school to give her a better chance?
