This comment fascinates me. I am a long time Mumsnet user (name changed), making my first post as an OP.
I was a relatively bright child, straight As up to 3rd year of senior school (in old money), when things started to go wrong.
I got tired of being bullied for being smart and driven, lost my confidence to in being different and dumbed down/rebelled to fit in, resulting in leaving school with 4 O levels - way below my potential.
My mum sent me to a local comprehensive (West Midlands) because it used to be a 'grammar'. Such was the due diligence 30 plus years ago
. Couple of years after I left, each entry year was closed to allow the school to run out before the school closed, premises bought...at least there was a reason behind the teachers (most, not all) being completely disengaged with us.
Anyway, that's my background, and I know this is not reflective of most schools today. With so many making choices where they can, by religion; location; intelligence; cost etc allowing), I am really interested in people's opinions on how children can definitely achieve their full potential in any given secondary environment, and therefore considering alternatives to their local state schools is not necessary...
