nurturing co-ed boarding schools for a year 7

Marlborough isn’t easy to get into.

Yes I know- DS just got waitlisted . Reason I mentioned it is that it's very popular with expat parents because of the full boarding structure and I think OP intends to continue to live overseas.

What are the boarding preps that are genuine full boarding in years 7&8? Not my area of expertise as my DC are at day school but would be helpful for the OP.

Marlborough isn’t easy to get into. Far more fashionable than the others. Why not go to a boarding prep and then co Ed senior school? You would have a lot more choice of senior school.

Hello- one oddity that you may not be aware of is that a lot of the coed secondary boarding schools only start in Year 9. There are some prep schools (Year 8 and below) that offer boarding but they're less common. and increasingly its "Flexi boarding" where children stay a couple of nights a week. The girls's only schools do often start in Year 7 but that doesn't help in this situation. There are a few coed boarding schools that start in Year 7 - Sevenoaks and Charterhouse off the top of my head- hopefully others will be along to advise further. My experience limited to South West - Bryanston might be an option although I can't comment on how many stay at weekends. Canford or Marlborough are others that aren't super academic but rigorous enough (in my opinion, anyway) and offer a good all round experience. If he's very sporty, Millfield might be an option.

The other thing to consider is that if you're sending him from overseas you want a school with a pretty big international contingent or that is a genuine "full boarding" school. You don't want a school that empties out at weekends, as many of them do, although I do have friends whose children board at a school like that and they enjoy the quiet Sunday to catch up with homework and recharge, so possibly depends on the child- but at least choose one that has Saturday school and pm matches so that it is just Sunday that things are quiet.

Also, not quite sure how to put this, but I'm coming from the perspective of having lived in HK for some years. If you are also from that part of the world, your assessment of "not the strongest academically" might be quite different to how they'd be assessed in the UK- i.e some of my HK friends consider 120-125 in UK standardised testing like ISEB "not very academic" whereas in UK that would be considered pretty strong and give you a lot of options.
