I am a governor, so I hear all the behind the scenes issues on this for us.
we are small Victorian building, bursting at the seams. We have one hall, which is quite small. Currently all the packed lunches eat in classrooms and the hot dinners just fit through the hall in staggered sittings. Dinners are cooked on site in a tiny kitchen pod which eats into our tiny playground space.
We had a letter sent home before Easter asking who would take up the new free meals, to get some idea of numbers.
One of our problems is that the kitchen will need to be enlarged, there is no space, and no money (as I understand it) to do this.
The other big problem is that most of our mid day assistants are also TAs. It is clear that we are going to have to change the timetable to stagger lunch hour in order to fit in all the sittings needed for hot meals. This means that the TAs would have to come out of class early/return to class later to be mid day assistants. Therefore the TAs can't do the job, and we need to recruit more midday people. We have had a midday vacancy for 6 months this year, which has just finally been filled. I don't know where the new assistants will come from, and I don't know what that means for those TAs who will loose mid day hours as they can no longer do it.
The hall is also used for PE, so our PE time is reduced. The KS2 classrooms all open off the hall, so the noise and disruption to their learning will also be an issue.
There is some suggestion that if KS1 child has a dinner, then parents are more likely to pay for KS2 child to eat, so our increase in numbers could be more than just KS1.
Current dinners cost £2:18, it goes up by about 5-10p every year. The dinners are OK, but not brilliant, my year 6 ds says the portions are too small for year 6. They don't like the cheap fish fingers or sausages for example. I really don't get why a mediocre school dinner is better than a packed lunch. Our packed lunches are pretty healthy.
The other massive issue for our school is the knock-on effect on pupil premium. if you no longer have to register as FSM to get a free dinner, then most people won't register. For a single class entry school in our area, in September, £66,000 of our budget will be pupil premium. £1,300 per child (in Sept) The school is working really hard to get parents to register as loosing this money would be a major issue. I know of one school which has a free prize draw for every child registered for pupil premium, the first prize, paid for by the school is a family holiday for 4. ( and it is a decent holiday too). The school has sent out a letter detailing this.
