DS has August birthday and has been educated at foreign curriculum school for past 6 years, outside UK. He will be 13 next August, so entering Year 9 Sept 2014 and possibly returning to UK (boarding) school. Should we hold him back a year? He is socially aware, bright and academically should be fine. BUT returning to British curriculum and young - maybe we should take the opportunity. Lots of articles relating to Reception delayed starts but can't find much on this age group. Any thoughts appreciated?
