In UK higher education, ethnic differences in academic attainment are ubiquitous and have persisted for many years. They are only partly explained by ethnic differences in entry qualifications. They vary from one institution to another and from one subject area to another. This suggests that they result in part from teaching and assessment practices in different institutions and subjects. We do not really know whether ethnic differences in attainment are reflected in variations in the student experience. We do not know what factors are responsible for the ethnic differences in attainment that remain when differences in entry qualifications have been taken into account. Finally, we do not know what aspects of teaching and assessment practices are responsible for variations in the attainment gap.
