This article on European universities' Englishisation (since the late 1990s) and rankings explores the link between Denmark’s eight universities' ranking on 7 notorious ranking lists and the degree to which English is employed in them. Some evidence supports a connection, but there are some striking deviations. The results may illuminate whether Englishisation at Northern European universities are best accounted for in terms of unplanned outcomes or reasoned choices. Despite a recent surge in research into Englishisation, it is not yet clear to what extent current organisational changes inevitably entail an orientation towards both rankings and Englishisation or whether a high rank can be attained without the use of English being increased and vice versa. Using as a case study Denmark’s eight universities, this paper examines the relationship between the combined rank on seven well-known ranking lists of each of Denmark’s eight universities and the extent to which English is used in them, drawing on recently compiled government statistics. The findings suggest that while there is some evidence in support of a correlation, in that lower-ranked universities are, on the whole, less likely to use English than higher-ranked ones, there are some notable exceptions. It is suggested that the findings may shed light on whether Englishisation at the universities of Northern Europe is best explained in terms of unintended consequences or rational choices.
