Surely it must do?
I've never really discussed schooling before with DH as DC is still so young. But I did recently and mentioned that if he showed promise or wanting to take the 11+, we would support him in any way possible.
He looked at me as if I had two heads and said "What's an 11+?
"
He really didn't know it was a thing and had never heard of it. I was shocked and mentioned it to SIL and her friend who also have 0 idea what it is!
I'm not from around here and I grew up in Essex. It was quite a big thing in that county, or at least the area I was in. You either went to a non Christian school which was absolutely terrible, went to a Christian school who were actually half decent or you did the 11+ if you were really bright. It was encouraged and supported.
Does it not even exist in some places then? I will look further into it but DH and close relatives/friends seem to be as clueless as him... maybe it isn't a thing in that part of the county
