Junior faculty wishing to achieve successful careers in academic medicine face many challenges. To facilitate faculty in their career development, the authors implemented and evaluated an innovative collaborative, or peer-group, mentoring program at their medical school. Based on Rogerian and adult learning principles, the program incorporated development of skills in key areas for career development, a structured values-based approach to career planning, and instruction in scholarly writing. The 80-hour program has so far been conducted twice over two academic years (1999–2001) with 18 faculty (50% women). Quantitative and qualitative methods were used in the evaluation.
