Objective: To describe and evaluate an innovative approach for developing leadership skills in a cohort of medical students through an extracurricular programme. Methods: The study was conducted at King Abdulaziz University, Jeddah, Saudi Arabia, from April to June of the academic year 2014-15, and comprised medical students from all batches. Mixed-method design was used to evaluate the leadership development programme. Pre- and post-tests were conducted to assess students` learning and their satisfaction was evaluated at the end of the programme. Focus groups were conducted to assess the programme`s impact on participants` behaviour. Data analysis was done using SPSS 16. Results: Of the 55 participants, 45(82%) responded to the evaluation survey. Of them, 29(65%) reported intended changes in their leadership practices immediately after the programme, with 8(28%) of them reporting more than one change. The mean students` satisfaction with the overall performance of the speakers and programme organisation was high at 4.12±0.91 and 4.54±0.89, respectively. Conclusion: Early experience of the leadership development programme produced positive results. An intense programme analysis is required to fully understand this significant organisational need.
