This study aimed to monitor which undergraduate students collected formative feedback on their degree essays and to quantify any correlations between gender or summative mark achieved and whether formative feedback was sought. We carried out a study at the University of Aberdeen Medical School, involving a total of 360 Year 3 students, comprising all 177 students in the 2004 cohort and 183 in 2005. Data on gender and summative mark were routinely collected during the degree assessment processes in March 2004 and 2005. Students signed on receipt of their feedback. Less than half the students (46%) collected their formative feedback: 47% in 2004, and 45% in 2005. Overall, females were significantly more likely than males to seek formative feedback (P = 0.004). Higher achievers were significantly more likely than lower achievers to seek their feedback (P = 0.020). Our findings indicate that these medical students, particularly males and poor students, may not use assessment feedback as a learning experience. Female and better students are keener to seek out formative feedback that might be expected to help them continue to do well. We need to explore further why so many students do not access formative feedback, and develop strategies for addressing this issue effectively.
