This story about "unexplained" school moves has been doing the rounds: schoolsweek.co.uk/epi-one-in-12-secondary-pupils-removed-from-school-roll-in-unexplained-exits/
In our area, and presumably elsewhere, schools work together on a Managed Moves system. If a student is in danger of permanent exclusion their school suggests this as an alternative option to their families. It means students have the opportunity for a fresh start in a new school, and doesn't have permanent exclusion on their record.
Each individual school takes in approximately as many MM students as it loses - there is a panel of local heads administering this, to ensure no school is advantaged or disadvantaged relative to others. The Local Authority is also heavily involved.
So these moves are not "unexplained" at all.
Of course there are some students who end up making several moves and don't settle anywhere. They may ultimately end up in alternative provision. But there are many others that settle well after one move.
Why was this sort of scheme not mentioned in the report?
