Since the introduction of Modernising Medical Careers in 2005, the electronic portfolio (ePortfolio) and workplace based assessments (WPBAs) have become integral, yet anecdotally controversial, components of postgraduate medical training. In this multi-centre, survey-based study, we looked at core medical trainees and trainers in the Northwest London region and their opinions of the ePortfolio and WPBAs. Our results demonstrate mixed feelings regarding these tools, with 60% of trainees stating that their training had not benefi ted from the use of an ePortfolio. 53% of trainers felt that feedback sessions with their trainees were useful; however 70% of them cited diffi culties in fi tting the required number of assessments within their clinical schedule. Overall, if implemented correctly, the ePortfolio and WPBAs are potentially powerful tools in the education and development of trainee doctors. However, improvements in mentoring and feedback may be needed to experience the full benefi ts of this system.
