Growstuff as you will know this is for Free schools opening in 2021-2022, Michaela Community School opened in 2014. The last data that I saw said the school had 30% of it's pupils eligible for PP, the school isn't free to spend it as the head likes though. There has to be a statement of how the money is being spent to support those pupils who are eligible. It's one of the first things that an OFSTED inspection looks at. Interestingly, many schools spend it on TAs, having taken part in a number of Ofsted inspections I know that is seen as being a bit lazy and not necessarily the best use of the money. Interestingly the school is seen as doing very well by lower and higher ability pupils both in terms of progress and attainment. fwiw, PP does not equate with lower ability (but I'm sure you know that).
I'm Sure It's a Repeat of the Summer of 1976
