Higher education is increasingly positioned within a global market, compelling institutions to prioritize service quality as a critical component of their competitive strategy and long-term sustainability. This report synthesizes a body of academic literature to provide a comprehensive analysis of service quality in higher education. It begins by examining the foundational service quality models, particularly the SERVQUAL framework, and traces the evolution of more specialized, performance-based measurement scales such as HEdPERF and HEDQUAL, which were developed to address the unique characteristics of the education sector. The report then explores the central causal relationship where perceived service quality influences student satisfaction, which in turn fosters student loyalty. A detailed examination of this nexus reveals that student satisfaction often acts as a critical mediating variable, suggesting that the long-term benefits of quality initiatives are realized by a positive, subjective student experience. Furthermore, the analysis uncovers a significant and context-dependent finding regarding study modes, where perceptions of quality and satisfaction can vary considerably between full-time, evening, and distance learners. The report concludes with strategic recommendations for higher education leaders and identifies key areas for future research to deepen the understanding of service quality in an ever-evolving educational landscape.
