My dss started at a different school for year 12 and has been struggling making new friends at the school.
My two teens are in the same school and my ds in the same year as him. Dss choose this school and it is probably the best school in our area results wise.
The trouble is the school my dss came from is very inner city and a very different environment when it comes to the strictness and social mix. It was a faith school and was very relaxed about things such as being late.
This new school is very different it is more suburban and more strict. But it also has a very distinctive community and has great ethos.
My ds who is established at the school has said he sees dss on the outside of a group but not speaking to anyone in the group for a long period of time.
This was the opposite at the other school where dss had many friends and a solid group of friends he is still in touch with.
