The key drivers of employer investment in workforce training include improving the quality of a product or service, the adoption of new technology, and to meet legislative, regulatory or licensing requirements. Various types of training -- accredited, unaccredited, informal -- are accessed by employers to fulfil their training needs. This report focusses on employer's use of unaccredited training. As unaccredited training sits outside the mandatory reporting requirements of the nationally recognised accredited training system, administrative data relating to its use are not systematically collected in the National VET Provider Collection, therefore the true extent of its uptake in Australia is largely unknown. However, from the 2017 Survey of Employers' Use and Views of the VET System, around half of employers in Australia are looking outside the nationally accredited vocational education and training (VET) system to provide their employees with training to meet their skill needs. This study takes a closer look at employers' use of unaccredited training, explores why they use it, why they choose unaccredited training over accredited training, and whether it meets their skill needs.
