This study compares higher education outcomes among students who enter universities in the United Kingdom (UK) with either an International Baccalaureate (IB) Diploma Programme qualification or an A level qualification. Using data sourced from the UK Higher Education Statistics Agency (HESA) and the IB examination data system, the sample included all first-year students enrolled for a full-time first degree at a UK higher education institution (HEI) from the academic years 2013–14 to 2018–19. Although there was an increase in IB students attending a UK HEI between 2013–14 and 2018–19, overall, there were many more A level than IB students at UK institutions. The majority of IB students studying at UK HEIs had a domicile outside of the UK while A level students were much more likely to be UK-domiciled. To control for differences in background characteristics and academic preparation of IB and A level students, matched samples were created, allowing for fair comparisons on higher education outcomes in the UK. Results showed that IB diploma students were significantly more likely to attend a top 20 HEI, to graduate with honours and to engage in further study upon graduation.
