Learning specific behavioral objectives (SBOs) of 39 subjects in medical school have been used to criteria not only for teaching and evaluation of medical students but also for the national medical li censing examination for physician and selection examination for internship since 1993. In order to prepare the information and data for future revision of SBOs of medical school, author compared with the SBOs of 39 basic and clinical science subjects using selected 20 items of SBOs as the key of study. The analyzed results were as follows: 1. The repetitions of a few sort of same SBOs were founded among subjects and even in same subject by difference chapter with the frequency of 2-11 times. 2. Marking the level of SBOs as B was not consistent according with different subjects or even in same subject between difference chapters. 3. Some SBOs were inappropriately listed in less related subjects. For further improvement of learning specific objectives in medical school, it would be necessary to develop the revision task of SBOs for the education committee of each medical school with cooperation of the subject objective committee of The Korean Medical Association and The Korean Society of Medical Education.
