Media competencies are a set of skills that every individual should possess in order to be able to consume and produce media and digital and information products in a critical and analytical way. This exploratory and comparative work analyses the level of media competence among 1,676 university students and 524 professors in Brazil, Spain, Portugal and Venezuela. One of the main results shows that the level of knowledge of technology and interaction — which is linked to digital competencies — does not depend solely on age, thus contradicting theories of digital natives and migrants. Our study also found that the general level of media competence is no better than medium to low when considering language, technology, interaction, production and dissemination, ideology and values, and aesthetics. These results point to the need to develop transversal actions for instructing both university professors and students in media competencies to face an ecosystem dominated by fake news and disinformation, as well as public policies directed at improving these skills among citizens at large.
