A systematic review of qualitative primary data (2010-2021) was undertaken to understand how inequality is experienced by undergraduate students from disadvantaged socio-economic backgrounds transitioning to the UK labour market. A ten-step protocol for qualitative synthesis was adapted to guide the study, whilst the PRISMA flow diagram was used to report the search. Data was extracted from 14 papers with thematic synthesis used to analyse the results inductively. This review illustrates multiple barriers faced by disadvantaged socio-economic students in a competitive graduate labour market and the severe impact this may have on student career development. Disadvantaged students often apply more effort than advantaged counterparts in seeking work and internship opportunities and live more precariously, as they lack finance to buffer them. In contrast, advantaged socio-economic status students can act quickly to build their employability profiles from the beginning of their degree studies, with the strategic application of social, cultural and economic capital. The qualitative papers in this review complement previous quantitative research, illustrating that despite participation rates in high education increasing for disadvantaged students, their career outcomes have not generally improved relative to their more advantaged peers. The review includes recommendations for stakeholders including government, universities, careers services and employers.
