Yes, they are a great idea. Many moons ago, I was involved with a group in the village where I lived in setting up an after-school club. We even received lottery funding for a new building. Eventually, the club was able to open a breakfast club too, which attracted about a third of the pupils. Some of them had working parents, but not all. The children just liked coming to the club, because they had breakfast and could catch up with their friends before school.The teachers liked it, because punctuality improved and children were in the right frame of mind to get started on schoolwork and parents liked it, because they knew their children were safe and they could get on with their commute. The poorest parents could claim child tax credits for the fees.
