Tuition Fees (Per Annum)

The annual tuition fees for different categories of government-subsidised graduate programmes are set out here. The substantial tuition subsidy from the Government of Singapore comes in the form of a MOE Subsidy which is administered by the Ministry of Education (MOE) and is offered to all admitted students up to the maximum course duration. Students need not apply for the MOE Subsidy if they are eligible. International Students reading a government-subsidised programme can apply for the Service Obligation Scheme to pay reduced, subsidised tuition fees. Most government-subsidised programmes are deemed feasible by the University to offer the Service Obligation Scheme except for programmes listed here

Mandatory Miscellaneous Fees

Miscellaneous fees are typically levied on items that are either not covered or partially covered by tuition fee and grant/subsidy. All students, whether registered on a full-time or part-time basis, are charged the mandatory miscellaneous fees. These are due at the same time as the tuition fees. These fees fall into the following general categories – registration, student activity, health service and insurance, and academic-related – and contribute towards defraying the associated costs. Annual miscellaneous fees payable are set out in here
