Introduction United Kingdom medical graduates can apply for speciality training after completing a two-year internship (Foundation Training). Post-foundation training application requirements vary depending on speciality but fundamentally require key skills such as teaching, research, and leadership. We investigated whether medical student demographics impact their familiarity with post-graduate training pathways and application process. Methods This was a cross-sectional study using a Bristol Online Survey. All UK medical students were invited to answer a range of questions on their demographics and perceived familiarity with Post-Foundation Training Pathways (PFTPs) and Post-Foundation Application Process (PFAP). The data was collected between March 2022 and April 2022 and exported for further analysis. Statistical analysis was conducted in Stata v.17.1 using Chi-square tests. Results 850 students from 31 medical schools took part. Male students were found to be more familiar with PFTPs and PFAP compared to female students (p<0.001). Similarly, students from Black, Asian, Mixed Ethnic (BAME) backgrounds expressed significantly lower familiarity (p<0.001) with PFAP compared to their white counterparts. Younger participants reported lower familiarity with PFAP (p<0.001). Students from a medical background expressed a significantly higher familiarity with PFTPs and PFAP (p<0.001). Conclusion The impact of gender, ethnicity, age group and medical background on medical students’ self-reported familiarity with PFTP and PFAP are significant. Further studies are required to evaluate the impact of demographics on tested knowledge of PFTPs and PFAP and whether this impacts success rate at post-foundation applications.
