Equivalent Full-time Student Unit. Each unit has a weight or load assigned to it in specific courses, expressed as a proportion of the total full-time course requirement in a year. All enrolled students have an EFFSU value calculated on the units in which they are enrolled in each semester. The EFTSU calculation determines the HECS liability of a student. The weights of the full-time course requirements in a year normally add up to one EFTSU.
