This pioneering volume brings together established and emerging scholars to explore English Medium Instruction (EMI) through a critical lens across post-Soviet regions, including Central Asian republics and countries like Azerbaijan, Georgia, Latvia, Estonia, Ukraine, and Russia.

As English rapidly expands within educational spheres across these nations-driven by globalization, neoliberalism, and Englishization, this volume addresses a significant research gap by moving beyond traditional managerial and administrative approaches to EMI. The contributors examine how EMI intersects with five critical dimensions: ideology, policy, identity, social justice, and the politics of English. Rather than focusing solely on technical aspects like language proficiency and teacher training, the volume interrogates how EMI reshapes linguistic hierarchies, influences teacher and learner identities, and potentially perpetuates linguistic imperialism and Eurocentric paradigms. By situating EMI within local sociolinguistic ecologies and cultural contexts, the authors advocate for more equitable, transformative educational practices that acknowledge multilingual repertoires and indigenous knowledge systems. Bringing together empirical data and theoretical analyses of various critical aspects of EMI, the contributors shed light on the nuances, complexities, challenges, and opportunities that these highly diverse multilingual post-Soviet contexts present.

Offering frameworks for recontextualizing EMI within Global South epistemologies, this book will be an essential reading for researchers, educators and policymakers engaged with language policy, internationalization, multilingual education, and decoloniality.
