As it stands, this could mean...
Compulsory schooling for all, 8-6
Compulsory before/after school sports/music/drama
Optional wraparound care (which many schools already have or don't have because it's not viable/wanted.) This already exists, it is not news.
It could be...
Run by outside providers (this will not be funded by the government-parents will, no doubt be charged!)
Run by teachers (which would necessitate dismantling the teachers' pay and conditions and would have a huge knock-on on the quality of teachers and teaching in the future. If they want teachers teaching from 8-6 so that parents can work, you can kiss goodbye to school holidays in the future; if Gove has sorted the problem of term-time childcare, Gove won't want working parents using those pesky holidays as an excuse not to get a full time job! Will private schools be following suit..?!
Notice Gove has not offered up any suggestions about how I he intends for this to be implemented. He's just letting the teachers object, so he can comment on now workshy they are later, and a handful of working parents rub their hands together with glee thinking they're about to be hundreds of pounds better off a month without all those childcare costs.
Tell us exactly what you have in mind, Mr G...
