Equity with equality? Contextualising everyone can widen participation in medical school admissions

Widening participation outcomes in admissions to UK medical schools have not changed 2007-2018, partly due to inequity in selection. This study models the effects of changing selection, using a novel method of contextualising applicants, on widening participation. We studied 1084 English school leaver applicants to a single medical school over two years, using data from their public exams taken 2 years pre-application (GCSE) and recent admissions test (UCAT). Widening participation was defined by postcode. We modelled two shortlists for a pre-determined number of 500; one ranked on UCAT total score, and the other on a metric that contextualised applicants' GCSE grades against their schools' average GCSE performance. There was a significant difference in the postcode-defined widening participation characteristics of the two shortlists; 46% by contextualisation and 32.2% by UCAT (Chisquare p < 0.00001). As widening participation covers 42% of postcodes, the "contextualise everyone" method achieves equity. Conventionally, contextual admissions identify individuals belonging to under-represented groups and gives them preferential treatment. Changing the rules for everyone, by using a relative attainment instead of simple absolute attainment metric, benefits from treating applicants equally; and could promote equity through widening participation.
