Summary The paper proposes a model to describe marks as awarded to students who select and sit for examinations in a subset of the courses offered. For each subject a linear transformation of the raw marks is sought so as to place all marks on a common scale. In this guise, the set‐up reduces to a simple linear model with multiplicative interaction term, totally lacking in balance as would result from experimental design practice. A variety of methods of estimating the linear transformation parameters is described.
