The FT executive education ranking measures performance on a relative, rather than an absolute, basis. The top business school in a single category is awarded a maximum of 100 points and the rest a proportion of this. The first nine criteria use data collected from the customer survey. The intended further use criterion measure whether customers intend to use the school more often, less often, or with the same regularity in future. The statistic used was a weighted average of their responses.
Preparation reflects the customers' rating of the preparation of participants by the school.
This, together with the next six criteria, is based on a five-point rating. For the teaching criteria, customers were asked to rate the schools according to the quality of teaching received. Diversity in the classroom measures both the level and diversity of participants from other continents. In particular, European schools were asked to classify all European students as home students, counting only those from Asia, for example, or the US, as international. For the new skills taught criteria, customers were asked to rate the ability of users to put into practice newly-acquired skills on their return to work.
