The recent growth in privately administered secondary education in many developed countries has been a widely observed phenomenon. The Australian private secondary school sector has grown faster than those in any other "OECD" nation, even though the average tuition fees charged by these schools have increased at double the nation's overall rate of inflation. In this paper, we employ a panel data set to estimate a set of hedonic price indices for private secondary schools that cater to different segments of the population in order to determine if and how changes in their characteristics influence the changes in fees.
