CauliflowerSqueeze - bit of a weird post!
I queried why the school policy had been changed as the previous policy had served all the hundreds of other children at my dcs' school just fine till now, without, apparently mass chaos. 
And, indeed, hundreds of thousands of other dcs at schools round the country previously.
I would probably have been a lot more neutral about the change in policy had the school simply done what many teachers/parents here say their schools do, eg mrz, namely provide whatever stationery they want the dcs to use, themselves. Or just ask dcs to bring in a plain pen.
But no, parents at my dcs' school have been given an exhaustive list of 30 different items. All of which must be bought by the start of term and confirm precisely to specifications, eg "Solid clear protractor - not the protractor with a gap and not coloured " - yes, that specific. I have no idea what that even means, but if my dc brings the wrong one, they will be punished, so I have no choice but to spend my Christmas sourcing all of this extra stuff.
So no, I'm not thrilled. If the school wants it, they should provide it. Feel sorry for anyone with multiple dcs - that could be 90 items to source and pay for by Jan.
