I suggested that some measure of proof that the policy is worth the time it takes—half an hour of travel and visiting time per child is a low estimate if tea and biscuits are offered at every house. For a class of thirty, that's fifteen hours of teacher time minimum. Someone said it uses up the first week of term, preventing children from going to school for that week. That is worthy of careful consideration as much as the 'policy' is.
I don't call preventing a few tears justification when other, less time consuming activities (see below) could probably do the job just as well.
I agree that some children (not many if my experience is anything to go by—some of you may think it isn't) will benefit from a teacher visit, but I very much doubt if most kids actually need it. That many of them will like it is another matter. They'd probably like a communal teaparty at school just as much. That way they'd see some of their classmates before starting school too.
I called the visits pussyfooting because it seems to me it is mithering away at the edges of real problems—classes too large, schools too large, not enough teachers, etc.
In addition (and I'm aware that I'll be slammed by some for this), I don't have a lot of sympathy for the weepy parents. For goodness' sake! they've had four+ years to get used to the idea, to prepare themselves and their children for the inevitable*. I don't believe I'm the only one who went home after the younger children were installed for their first half-day, sat down, put my feet up, and immersed myself in a good book, joyous at just over two hours peace and quiet.
*except for home schoolers, natch.
