At our local school, PP is high. They have extra money and they struggle to spend it.
They want PP children to be in school at least 92% of the time, which is the same as the non PP.
However, they are not actually dealing with the issues.... PP families are more likely to be single parent households, have children with SEN, have less educated parents, live in worse areas, worse housing, have more children, less access to transport, have mental health issues, more likely to have SEN themselves, often they also put no value in education... All of these issues work against them in getting their children to school.
You can throw thousands of pounds at these children, but if they are not in school and are not supported to learn, it is just wasted money.
