Many institutions have applied a tutorial system to medical education since Tokyo Women's Medical College started doing so in 1990. Chiba University School of Medicine started a clinical tutorial system in April 1997 and has continued it for 4 years. Our system has employed problem-based learning using cases, with the goal of students' acquiring self-learning and problem-solving skills. This tutorial system has been positively evaluated by both students and instructors and is likely to be useful for clinical medical education.
