Yes, I see your point, nina but I think the cost in teacher time that janea describes is too "expensive". The approach that goldengirl describes seems like a much better and more efficient idea.
There is also the fact that most (?) kids nowadays will have been to a playgroup or nursery already by the time they are old enough to start school so they have some experience of being in the charge of someone like a teacher.
Why do restaurants and takeaways close so early now?

At the end of each school year they also spend a couple of days in the class they will be joining so they can get to know the teacher - and vice versa.
