Our DS is at the local primary in tiny village - 2 class intake, reception to Y2.
We are in a rural, low-income area and there are a % of traveller kids and families with generations of "home education" as a lifestyle choice (i.e. a strategy to get UC without working - no educating going on).
The school used to allow any child who wasn't enrolled elsewhere in the county to join the roll if there was space - so that if e.g. a traveller child was in the area for 3 months, they could come to school if they wanted. Same for the "home ed" kids, if they had a chance to access the school, they could take it. Uniform was optional to allow even more flex.
It's a really great school from what I've seen - child-centred, plays a role in the community, very broadly aiming for the best access to education for every child.
At the last Ofsted they got a lot of outstanding, a couple of goods, and then "inadequate" for attendance (due to the flexi kids places). The inspector also noted that the flexibility on uniform was bad for the children.
Overall the school was rated "inadequate".
So now the school has changed its policies, no longer gives out those flexible places and uniform is required. The end result is some children are now totally excluded from any contact with a mainstream school, when they could previously access it. Which I believe is a bad outcome when viewed from the perspective of 'what's best for the kids'.
We also know of a child with SN who was off-rolled after the parents were dragged into the 7th meeting about his excessive absences - the stress of the school meetings was negatively impacting him and it was easier to take him out of school. Again, this wouldn't have happened pre-Ofsted scolding the school over attendance.
