How the calculation works
Raw English and Maths scores are converted to standardised subject scores using the 2025 paper data. The report applies an age adjustment factor to both subjects, calculated from “days younger” than 01/09/2014, before the two subjects are combined into the overall standardised score. The standardised scale has an average of 100 and a standard deviation of 15 across 5,113 candidates.
