This paper undertakes a comprehensive review of the existing literature concerning English-medium instruction (EMI) within Higher Education Institutions in Kazakhstan. EMI is a fast growing global phenomenon pushed by the internationalisation of higher education in pursuit of building a competitive, highly qualified human capital. An upward trend is observed in the number of universities incorporating English-medium programs, with 44 universities currently facilitating special EMI groups. In order to explore the research on EMI, scientific literature from featured electronic databases was searched by inserting the relevant key words. Our research discloses that a preponderance of studies examining EMI in Kazakhstan focuses on graduate programs, leaving undergraduate-level EMI relatively unexplored. Moreover, the provision of quality assurance for EMI, an essential element that incorporates the needs of all stakeholders, is a considerably under-studied area. The scarcity of knowledge in this area lends urgency and relevance to our research.
