The Free Tertiary Education Scheme (FTES) was implemented in Mauritius in January 2019 to improve accessibility and inclusivity in higher education. This study rigorously assesses the sustainability of FTES under escalating financial pressures on public financing and advocates for a unified tuition scheme to guarantee fair and efficient resource distribution. The methodology entails a thorough examination of tuition and administrative fees of public higher education institutions (HEIs) receiving FTES, classifying programs by qualification levels, topic areas, and delivery methods. Comparative and statistical analyses were conducted to identify differences in fee structures, specifically between full-time and part-time programmes, as well as between STEM and non-STEM disciplines. The results reveal considerable discrepancies in tuition fees, with certain universities imposing significantly higher charges, thereby provoking apprehensions over cost inflation and financial viability. Recommendations entail establishing a uniform tuition and administrative fee framework correlated with qualification levels and program attributes. This chapter recommends the establishment of transparent management charge rules, regular fee assessments based on inflation, and a gradual implementation approach to facilitate a seamless transition and adherence. These initiatives aim to enhance financial sustainability, promote accessibility, and prevent exploitation within the FTES framework. A unified tuition plan will ensure the sustainability of free tertiary education in Mauritius and strengthen the country's dedication to cultivating a knowledge-based economy.
