British School of Riyadh Vs London day schools

I can imagine how difficult this decision is if your current school is rated by ofsted as outstanding in the UK. If not I would not worry very much. Nevertheless as they are still young, you could try the British School in Riyadh- maybe make an enquiry first if any positions are still available for September 2021.  If they have places you can go there for a year and if you are not happy you can return with the kids to the UK or let eg. the older one finish their GCSE's there and then send him/her to a very good private college in the UK where they gear students for A's for A levels in 18 months. Just some thoughts.

Having lived in the middle East for 32 years I was more than happy as both children had the best education and went to universities. The A level results they had at Dubai College were second to none and both did well.  In Riyadh, the British International school of Riyadh has  an excellent reputation with equally outstanding A level results. I would highly recommend you get in touch with the school where you can meet with informed staff and address your concerns. I really hope this helps- I know you will not be disappointed.
