The purpose of this study was to identify the professional and personal competencies that entry-level academic health sciences librarians should possess from the perspectives of academic health sciences library directors, library and information sciences (LIS) educators who specialize in educating health sciences librarians, and individuals who serve as both LIS adjunct faculty and practitioners in the field of health sciences librarianship. The first six research questions focused on the identification of professional and personal competencies, and the last two research questions focused on comparing and contrasting the three perspectives on the professional and personal competencies. The eight research questions were addressed through four rounds of the Delphi method. Three panels of experts, initially composed of 13 academic health sciences library directors, 8 LIS educators, and 8 LIS adjunct faculty adjunct faculty/health sciences librarianship practitioners, participated in the study, and most participants were female, white, in the age range of 45-64, had less than 20 years of experience in their respective careers, and were members of the Medical Library Association. The data collected from the rounds of the Delphi method were analyzed using descriptive statistics, including measures of central tendency, and non-parametric statistics, including the Kruskal-Wallis and Mann-Whitney U tests. Two major conclusions that can be drawn from the findings of the study are: (1) personal competencies are as important as professional competencies and (2) the professional and personal competencies developed by the LIS educators who specialize in health sciences librarianship education were preferred over the ones developed by the academic health sciences library directors and LIS adjunct faculty/health sciences librarianship practitioners. Experts in the field of health sciences librarianship have created a comprehensive inventory of both professional (knowledge and skill) competencies and personal (self-concept, trait, and motive) competencies that can be used in professional practice as well as educational planning.
