'So it's how do you square that circle? How do you remain true to the original creation and concept and yet at the same time not offend people in the 21st century? This ranking measures the quality and breadth of the schools’ postgraduate programmes. It is based on their performance in the four main rankings published by the FT each year: MBA, Executive MBA, Masters in Management and Executive Education. Only schools that take part in all four rankings are eligible for a full score.
