The informative treatment of educational outcomes reveals fundamental aspects of educational policies. This study examines media representations of international (PISA 2015 and TERCE 2013 for Latin America) and national (ECE 2016 for Peru) assessments constructed by the Peruvian press through informative notes of digital versions of the main printed periodicals. The methodology used was interpretative analysis of the quantified contents obtained from newspaper repositories. The information was extracted and organized in texts or units of significance, which were reproduced as news-values. The results confirm the predominance of media representations of the PISA test over the ECE and the relegation of TERCE. The mediatization and politicization of educational evaluations are expressed through messages about the failure of the national education system that highlight the last positions in the ranking, ignore improvements and generate a sense of social alarm.
