This occasional paper is the seventh in a series on the National Quality Framework (NQF). It explores the quality of children's education and care services based on the socio-economic status of the area in which they are situated. The Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Advantage and Disadvantage (IRSAD) is used by the Australian Bureau of Statistics (ABS) to classify services by the level of relative socio-economic advantage and disadvantage of their local area. This paper uses SEIFA as a proxy measure to identify services that are more or less likely to educate and care for children from disadvantaged backgrounds. This paper begins by highlighting contemporary research about the association between socio-economic status and developmental outcomes, and the impact of high quality education and care on children from more disadvantaged backgrounds. It then outlines the quality and availability of education and care in low socio-economic status areas, analysing service quality ratings and reassessment results. The paper also examines differences across service and provider management types, and remoteness classifications. The detailed analysis suggests that there are differences in the overall quality ratings of education and care services located in high and low socio-economic status areas. Services in relatively disadvantaged areas are slightly more likely to be rated Working Towards NQS and notably less likely to be rated Exceeding NQS than those in relatively advantaged areas.
