Increasing education and training is considered one means by which to reduce the extent of social exclusion and as such has been a key focus in recent public policies. This study investigates the impact of education and training on the extent of social exclusion using a measure of multidimensional social exclusion. A simulation of the effect of the COAG target relating to halving the proportion of 20-64 year olds without at least a certificate III qualification between 2009 and 2020 on the measure of multi-dimensional social exclusion is also undertaken. The study finds a clear dichotomy in the extent of social exclusion experienced between those with low levels of education (early school leavers or those with a certificate II qualification at the most) and the rest.
