This is a story on the BBC's website based on a report by the Headmasters' and Headmistresses' Conference.
This comment in particular is very interesting:
"Heads will say our most able pupils who don't use the buzz words don't get the top grades - but they produce the most novel and insightful answers. The markers can't accommodate the originality of their answers.
"And the most depressing thing for a teacher with a high calibre of pupil is to coach the most able pupils on dumbing down their answers to get an A*," he said.
I think this has always been the case to a certain extent but the situation now, if it is true, represents the culmination of years of what I've always called 'the cult of mediocrity'.
It's not just schools where this is the case. The workplace is rife with it as well.
