This is also a solution and one which works also for those not born in the country but are moving in when they are older. It does put a drain on the school system though and at least here in Norway the budgets are pretty tight already. And considering we do not pool students like you it also means that the rest of the class has to wait or that you have to leave those that do not speak the language behind the curve. I guess it still comes down to prioritisations of the politicians. A combination of training in daycare and making separate pools in the school would be good.
