The purpose of this study is to present a diagnosis of the level of development of the informational and digital competencies that the postgraduate students of the University Center of the North (CUNorte) possess. These two variables of Information Literacy are evaluated through a questionnaire organized in five dimensions: capacity, access, evaluation and use of information; and basic notions in the use of Information and Communication Technologies (ICT). The results show evidence of some of the competencies acquired by students and graduates of postgraduate courses, however there are opportunities to strengthen their disciplinary development and facilitate their research processes. The answers provided by the students and their consecutive analysis highlight the need to complement the diagnosis using other techniques to assess the knowledge and skills that make up the informational and digital competencies whose development is evaluated. Regarding the contribution of the study, considering the factor analysis of the component matrix rotated in the instrument, it is summarized that it is feasible to develop a diploma that provides the necessary tools to enrich the aforementioned competencies.
