Australia's economic recovery from the COVID-19 pandemic depends on the ability of employers to fill the skills shortages resulting from lower migration and upturns in economic prosperity associated with ongoing technological change. The national vocational education and training (VET) system is best placed to support employers to meet these skill needs. However, data from the Survey of Employers' Use and Views of the VET System show that, prior to the onset of the pandemic, employers' engagement with the VET system had trended downward over the previous 14 years up until 2019. This research examined the factors in the current VET environment that influence employers' decisions when choosing training options, in particular, nationally recognised training. The research is based on interviews with a range of peak stakeholder bodies in late 2020 and early 2021 and of employers between March and June 2021. The research was supported by a review of the most relevant national and international literature. According to the peak bodies and employers interviewed, the development of more skill sets is linked to the need to reduce the number of existing training packages. Also acknowledged is the reality that many employers have a limited understanding of nationally recognised training, underlining the requirement for improved messaging as a starting point for better engagement.
