LCME Standard 6.3 Self-Directed and Life-Long Learning
The faculty of a medical school ensure that the medical curriculum includes self-directed learning experiences and unscheduled time to allow medical students to develop the skills of lifelong learning. Self-directed learning involves medical students’ self-assessment of learning needs; independent identification, analysis, and synthesis of relevant information; appraisal of the credibility of information sources; and feedback on these skills.
The LCME does not stipulate that schools have to utilize TBL/PBL, nor does it prescribe a certain percentage of lecture/non-lecture. However, TBL and PBL are both tried-and-true methods to satisfy standard 6.3, and schools that have gotten in trouble for being too lecture-heavy have been able to become compliant in part by cutting lecture to less than 50% of contact time. Hence, if you want to attend an accredited medical school, you will likely be attending one that has a -BL in lieu of 40 hours/week of lecture.
