I believe it is the same exam and there is the possibility of sharing scores
However as RM says I doubt there are more than the odd one or two opting to share scores as geographically they aren't anywhere near each other. I don't think I've come across anyone on the forum who has.
You have probably not been looking hard enough, Tinkers

.
The score will vary according to the cohort it is made up of. So for example, if everyone who registers for CCHS also registers for Woodford and nobody else does, and none of those Woodford registrants register elsewhere either, the standardised scores for each will be the same.
If the two cohorts aren't exactly the same girls, it's unlikely to be a blanket difference between scores, because each raw score which differs from the core joint set will be a different amount away from the mean.
Anyway, do you want to live in / near Slough, in / near Chelmsford, or within the common catchment area for the Redbridge grammar schools? I know which one I'd vote for, but some people actually like Slough. And Ilford and it's environs. Chacun a son gout, as the French say with more accents on.
