gillybob you did misread my post. I talked about a broad brush guide. I didn't say anything about home visits to any homes. I was saying that I did not actually see a need for any home visits.
The estate that feeds DGC's school is not one where many, if any of the flats, have been sold to private buyers. Most of the families on this particular estate suffer some kind of deprivation, including poverty, disability, unemployment and drug abuse. Children from even the best and most loving family which is struggling to cope with these problems, is probably going to need some extra help and vigilance when they start school.
Those from the owner occupied houses are not 'posh', nor again did I suggest it, that is your gloss, but they come from more affluent homes where their parents can, and, generally, do provide more resources for their children, whether it is going on holidays or outings to leisure and learning facilities or visits to cultural venues like museums, theatres and music. Like it or not, this kind of background gives children a head start when starting school.
One of the joys of DGC's school is how well they cope with this mixed intake, how well the children get on. DGD's invitees to her birthday treat included friends from across the whole of her school's catchment area
