According to the 1960s pop hit, it was the year 2525 when we all started to notice dramatic changes to the world we live in.

That, according to one projection put forward at the conference organised by the Westminster Education Forum, is the date by which humans will be removed from the marking of the exam system and artificial intelligence will take over. The projection is extreme, but the system is already on course for computers to have a far bigger role in the marking of the system. It throws up some interesting dilemmas.
