This paper investigates degree classification outcomes for students with SQA Higher qualifications at an elite Scottish university. Students are characterised according to a new indicator based on their secondary school's academic performance relative to the national (Scottish) average. The results show that our school context indicator provides valuable information for interpreting school qualifications with respect to a student's potential to benefit from their university studies. If school context is ignored, raw school grades alone may be an incomplete measure of academic ability and the probability of success at university.
