This article explores the extent to which students of different ethnicities, (dis)abilities, sexes, POLAR groups, and academic abilities undertake Year in Industry (YINI) placements and realise post-placement academic improvements, in comparison with non-YINI students. The benefits of work placements on student employability and graduate prospects are well-documented but less is known about which student groups gain access to placements. The study analyses secondary data relating to the sex, ethnicity, disability, POLAR group, grades, and degree classifications of 31,159 undergraduates graduating from a UK Russell Group university between 2016 and 2023, representing the largest study of its kind to date. The study found that students completing YINI programmes are significantly more likely to achieve first class (70.1% YINI, 28.5% non-YINI) and good degrees (97.7% YINI, 83.6% non-YINI). Importantly, the study found that YINI completion narrows awarding gaps found in the non-YINI population in relation to sex, disability, ethnicity, and POLAR group. The potential gains are greatest for male students, students with disabilities, Asian, Black and mixed ethnicity students, and students from low POLAR groups. However, access to placements is not proportionately distributed. Female students, students with disabilities, students from all ethnic minority groups and those of unknown ethnicity, and students from low POLAR groups are under-represented within the YINI population, suggesting placement access gaps in relation to sex, disability, ethnicity, and POLAR group. The paper concludes with strategies to encourage YINI participation amongst diverse student groups and calls for further research into lived experiences of YINI and non-YINI students.
