Schools in UK send police to homes of absent pupils

1) the police do it
2) dedicated 'truant officers' do it
3) social services do it
4) noone does it
Of the 3 that actually achieves anything, I suspect the police doing it is likely to be the least power-trippy, dedicated truant officers would just be too expensive, and social services are also run thread-bare by the tories to the point where they'd not really have time for it either.
If they're deliberately missing from class then chances are high that they wouldn't be productive in the class either.
I would say that option 4 would achieve the most, because it avoids the harm that the first 3 create.
Sending the police, instead of someone to help the students and parents, is not the right approach, as the article points out
England != UK
So I guess this is about problem kids and/or parents who can't get their shit together.
Apologies for not giving a more detailed answer, its late at night.
The rules are normally around consecutive days of absence.
But also because wealthy parents don't take their children out of school to go travelling. There is a reason that boarding is popular.
