Training of assessors, developing of data recording systems, and data management will be part of this effort. he professionalism values will be integrated into the education system and several committees will be established to focus upon the education and effective implementation of the project. A webpage and faculty development system focused on training professionalism education and assessment of the faculties will be created by faculties from the four CMB medical education center. A research agenda including the assessment of baseline knowledge, attitudes, behaviors and outcome measure will be initiated and an affiliation agreement between medical schools in China will provide collaboration in dissemination.
