The public exams system in England has long been concerned with comparability between subjects. Published research on this issue dates back to at least 1928 (for example, Crofts and Caradog Jones), and has at times proved to be highly controversial (for example, Fitz-Gibbon and Vincent, 1994, vs. Goldstein and Cresswell, 1996).

Studies have often built on one another, and the debate has developed significantly over time. This paper puts this discussion into its historical context.
