Towards sustainable tertiary education funding in Trinidad and Tobago: integrating sin taxes, education savings plans and income-contingent loans

Trinidad and Tobago’s Government Assistance for Tuition Expenses (GATE) programme, once a universal free-tuition mechanism, now faces acute fiscal strain amid declining petroleum revenues, tighter budget allocations, and growing affordability pressures for students and families. This paper examines a sequenced three-pillar framework for tertiary education financing that combines earmarked tobacco and prospective cannabis excises, a matched national education savings plan, and income-contingent loans. Using Trinidad and Tobago data wherever possible, and external cases mainly as institutional or benchmark references, the analysis finds that, under full implementation, moderate excises could broadly cover current GATE tuition outlays. Matched saving can materially reduce debt for households with stable saving capacity, but it is not a universal solution for low-income families. Income-contingent loans can protect access if domestic tax-based recovery is strong, though overseas recovery should be treated conservatively. Sensitivity analysis shows that if one pillar is delayed, the model remains workable only through phased implementation and protection of means-tested GATE. The paper’s contribution is to clarify complementarities, sequencing, and transferability for small, resource-dependent states rather than to resolve every pillar-specific debate.
