What Purpose Does Ranking Serve? - 2 Publicity for institutions that are well ranked. For instance, the Vice-Chancellor can make a boast that his/her university is among the top 10 in a programme. The Head of Department can flaunt the information that his/her medical programme is the best in the country Fuel for the advocacy machinery of student and staff unions for improved funding for the system Excuse for employers to deny employment to graduates Supporting evidence for critics that graduates are halfbaked if universities earn low ranking on league tables 16/03/2018 OKEBUKOLA-NUC RANKING WORKSHOP 45
What Purpose Does Ranking Serve? - 3 Indication of the quality of delivery in the university system Stimulus for university administrators to buckle up to avoid the ridicule of being low down in the league table Salmi and Saroyan (2007) report that in some countries authorities restrict scholarships for studies abroad to students admitted to highly ranked institutions; donor agencies and foundations also look at international rankings to inform their decision making 16/03/2018 OKEBUKOLA-NUC RANKING WORKSHOP 46

What the Critics say about Ranking “I imagine that all university heads broadly share my own view of these [league] tables. They are terrific and unquestioned when you score well and better than last time. They are fatally flawed and fundamentally unfair when you move in the opposite direction. ” …Howard Davies, Director, London School of Economics 16/03/2018 OKEBUKOLA-NUC RANKING WORKSHOP 53
Controversy of Ranking • Any ranking is controversial and no ranking is absolutely objective. • University rankings become popular in many countries. Whether we agree or not, ranking systems clearly are here to stay. • The key issue then becomes how to improve ranking systems for the benefits of higher education (IREG). 16/03/2018 54 OKEBUKOLA-NUC RANKING WORKSHOP
