We investigate the extent to which graduate returns vary according to the class of degree achieved by UK university students, and examine changes over time in estimated degree class premia. Using a variety of complementary datasets for individuals born in the UK around 1970 and aged between 30 and 40, we estimate an hourly wage premium for a ‘good’ (relative to a ‘lower’) class of degree of 7% to 9%, implying a wide spread around the average graduate premium. We also estimate the premium for a good relative to a lower degree for different cohorts (those born between the mid-1960s and early 1980s), and find evidence that the premium for a good degree has risen over time as the proportions of cohorts participating in higher education have increased.
