Academic support is an important part of quality education provision in higher education institutions (HEIs). Although many researches discuss about the different approaches and their effectiveness of academic support in retaining students and meeting their diversified needs, there is not so much literature written on the academic support in transnational education (TNE) under the strategic goal of sustainability. Based on an integrated analysis of a Chinese-Finnish TNE program, this paper uses mixed methods with qualitative and quantitative approaches in a case study to analyze what academic support should be provided to students, how and when it should be provided. Findings show that students need academic support in the aspects of employment-related issues and courses learning most. And Fu Dao Yuan is suggested to be the links between students and academic support mechanisms. The paper also proposes a longitudinal model of academic support to achieve Sustainable Development Goals (SDGs), which can be a reference model adopted in other TNE in the Chinese context.
