There appears to be a direct as well as an indirect link between the scholastic presence of the English language at any particular university and its respective Times Higher Education-Thomson Reuters 2010 World University Ranking, one of numerous world university rankings. Due to the author's familiarity and to some extent intimate relationship with THE-Reuters World University Rankings, its statistics are exclusively employed to emphasize the intended function of this paper. The claim is made using data sets from THE-Reuters rankings by way of a Korean model in a global tertiary educational context. Effectively, since it is the objective of a growing number of universities worldwide to improve their THE-Reuters World Rankings, it is thus the purpose of this paper to quantitatively depict the growing necessity of English language use in the context of delivering lectures at the tertiary level, so as to make a documented attempt with regard to persuading non-complying universities to offer additional English mediated lectures.
