BACKGROUND: International medical graduates (IMGs) currently account for 41% of the UK medical workforce. IMGs in training posts face challenges in progression including a significant 'award gap' (previously differential attainment) in postgraduate training compared to UK medical graduates. General practice (GP) is disproportionately impacted by these issues as over 50% of GP trainees are IMGs. Previous studies focusing on educational interventions to reduce the award gap have failed to improve training outcomes. AIM: To identify literature addressing the factors underlying the award gap. DESIGN & SETTING: The scoping review will follow the process outlined in the Joanna Briggs Institute (JBI) guidance. Input was sought from a specialist librarian, patient and public contributors, stakeholders with lived experience of working as an IMG and experts in the research field. Studies eligible for inclusion will be those reporting educational outcomes (concept) for IMGs (participants) undertaking UK GP training (context). METHOD: Searches will be conducted in Medline, EMBASE, SCOPUS and PsycINFO for articles reporting educational outcomes for IMGs in UK GP training. A two-step screening process will be employed to identify eligible articles. Analysis will involve basic descriptive statistics reporting the number and type of evidence sources. Reporting of the data will be in line with the PRISMA-ScR checklist and will include visual representations of findings including graphs and figures developed with stakeholders and PPI group members. CONCLUSION: By exploring the literature which reports the factors underlying the award gap in GP training we will identify areas for further research.
