We assess whether ethnic minority pupils are subject to low teacher expectations. We exploit the English testing system of “quasi-blind” externally marked tests and “non-blind” internal assessment to compare differences in these assessment methods between White and ethnic minority pupils. We find evidence that some ethnic groups are systematically “under-assessed” relative to their White peers, while some are “over-assessed”. We propose a stereotype model in which a teacher’s local experience of an ethnic group affects assessment of current pupils; this is supported by the data.
