Apologies as it's related to things years ago and times are different. I'm thinking about it as going through diagnostic procedures for ASD now as an adult.
I remember being so happy in my first two years of school with lots of friends in my class, we all sat at a big table as you do as small kids. Invited to lots of parties and playdates with others. Then when we moved to next level, all friends were kept together and I was put in other class with none of my friends. The friendships all fizzled out.
What I'm wondering is if parents thought I was weird and didn't want their kids to be friends with me? So asked school to do this?
Or maybe if I do have ASD (don't know for sure yet) maybe those kids were maturing far faster than me and so didn't like me anymore and complained to parents about me?
My old reports say I wasn't good at mixing with others. Primary school was never the same for me after that, I never made nice solid friendships in school after (although had on-off friendships, ended up the butt of the joke a lot) and was on my own a lot. Painful process of learning to mask and try hard to be normal, so was better at high school. Have good friends from high school still today.
If a child was acting odd, would that be a reason to move them from a group of normal friends, as a teacher? Like I say though, those kids might well have started to dislike me anyway.
