Why is there a graduate earnings premium for students from independent schools?

We examine the determinants of occupational earnings of UK 1993 graduates and focus on the influence of the type of school the graduate attended prior to university entrance. For data reasons, we restrict attention to graduates who attended school in England. We estimate that, on average, a male (female) graduate who attended an Independent school receives an earnings premium of 3.1 per cent (3.4 per cent) over and above the earnings of a graduate who attended an LEA school, ceteris paribus. We also find considerable variation across different Independent schools in the size of the graduate earnings premium, especially for males, and show that in the case of males the premium increases with the level of school fees, but is not statistically related to measures of school–level average academic performance
