How long is reasonable for a child to miss school when visiting a parent in another country ? Child (junior school age) of a friend is currently staying with parent in the UK. Child normally lives in another European country - child is staying in the UK until October currently (arrived in April) and friend has no plans to register him at a school. Is friend allowed to do this (as in keep him out of education for 6 months?) 
Friend works f/t so won't be homeschooling
