By looking closely at the evaluation de digital contents of educational materials, this work examines information competencies within information literacy programs and their impact on the performance of postgraduate students. An initial examination of Social Sciences postgraduate student academic information consumption habits is made, followed by an analysis of the features of digital educational contents required to assess quality of learning and determine the efficiency of learning objects within specific information literacy programs. The paper then presents the impact of the assessment of digital educational contents as a means of demonstrating information literacy and as a tool for acquiring knowledge. The researchers also propose a model with evaluation criteria for assessing use of learning objects and the development of information literacy programs based on the competent use of learning objects.
