Qualification structure

A total of 1280 weighting points comprising: 520 core weighting points listed below; plus 760 general elective weighting points from the general elective units listed below. Choose a total of 760 weighting points elective units from the list below, of which between 0 and 220 weighting points can be taken from Group A; and between 0 and 540 weighting points must be taken from Group B; and between 220 and 760 weighting points must be taken from Group C, or all 760 weighting points can be taken from Group C. Up to 220 weighting points of the general elective units Group A, may be selected, with appropriate contextualisation, from any relevant nationally endorsed Training Package or accredited course, provided selected units contribute to the vocational outcome of the qualification. If weighting points are not listed for an imported unit in any other UEE qualification, default weighting will be 10 points. There are units of competency within this qualification that contain pre-requisites. Units of competency that have a pre-requisite requirement are identified by this symbol *. Refer directly to the units of competency to identify pre-requisite requirements to ensure all are complied with. A list of all pre-requisites is also provided in the UEE Pre-requisite Companion Volume. Where imported units are selected, care must be taken to ensure all pre-requisite units specified are complied with.
