The things you learn. Today, I discovered via the weekly school email that an organisation called London Challenge monitors the achievement and attainment of all schools in London. "To celebrate the 2006 GCSE results of many London schools, they worked with Transport for London to rename all the tube stations with the "successful" [their terminology] schools".
I can’t see very much additional information about how "London Challenge" selected the schools or how it chose where to put them on the map at the relevant page of the Department of Education and Skills website, but I can let you have a PDF of the actual underground map, which is attached to this post. My daughters’ school is on it, replacing Clapham North at the southern end of the Northern (aka misery) line, nine in from the end. (Nonsuch High School for Girls.)
