"Wouldn't it be wonderful if 'Learning Difficulties' became 'Learning Differences'."

You're way out of date, Lizzie. The phrase used in education these days is 'special educational needs' (SEO) and it refers to children who are 'gifted and talented' as well as those who have different needs. It is the obligation of every state school (not however, private schools) to provide whatever extra resources these children need. Most of them do this. I don't, however, expect you to accept this as it contradicts your biased and old-fashioned view of what happens in schools these days. But then, when did you ever let the facts get in the way of your prejudices?
