Is Universal Free School Breakfast Policy Half-Baked?

One of the unforeseen consequences of offering free breakfasts to all primary school children is that a lot more children will be arriving at school much earlier.

Without substantial supervision this is going to have negative consequences on pupil behaviour,

which will impact on learning throughout the day.

I don't see employing one teaching assistant as a solution.

Did any of the studies into universal breakfasts look into this potential negative effect?

The policy could be saving money on food but then costing a huge amount in supervision costs.

As a policy it seems a bit half-baked.
