Education agents are organisations and/or individuals who provide a range of services in exchange for a fee from their service users, including overseas higher education institutions and/or students who will study or are studying abroad (Nikula & Kivistö, 2018; Krasocki, 2002). As marketisation of higher education has intensified (Foskett, 2011), education agents have emerged in the international higher education sector, became essential to international student recruitment (BUILA, 2021), and appeared to play a significant role in international students’ decision-making process (University UK, 2017), which is however still under-researched in the literature to date (Feng & Horta, 2021). To better understand the role of education agents in the marketized higher education sector, this research explores Chinese international students’ experiences applying to postgraduate taught programmes in the UK from the students’ perspective. A longitudinal interpretative phenomenological analysis (IPA) approach is used, interviewing ten students at four stages throughout the application process from November 2020 to June 2021. Drawing on this dataset, this paper illustrates some Chinese postgraduate applicants’ thoughts around applications to overseas programmes and reflections on the value of their education agent over this procedure. In parallel, it also reveals that among the gamut of services that education agents provide, evaluating transcripts, selecting potential programmes and producing application documents are most valued by some Chinese postgraduate applicants, in which education agents are regarded as alternative labour, information navigator and insurance strategies. In addition, some important implications of the wide use of education agents for marketisation of international higher education are identified. We argue that marketisation has positioned education as a good that can be sold by universities, bought by international students, and promoted by education agents, which creates fierce positional competition for both agents and international students to gain access to prestigious international education and pushes them to adopt market-driven practices. On the other hand, universities are also in competition with one another, meaning information about their programmes are not always transparent, making individuals uncertain about their role within this market. Especially information associated with international application procedures and admission requirements for programmes overseas is less discussed in related research. We therefore call for close attention of policymakers, universities, researchers and other stakeholders to this particular issue. Where procedures and requirements rely on tacit knowledge, transparency and fairness may be called into question.
