Learning environments are among the many postgraduate educational aspects impacted by the COVID-19 pandemic. During this time, colleges and universities had to implement emergency remote teaching (ERT) to continue and keep their faculty, staff and students safe. From this context, this study's general objective was to analyze postgraduate students' perceptions regarding the learning environments experienced during the ERT from the COVID-19 pandemic. Thus, the research was conducted through a nationwide survey of 734 postgraduate students from different courses. Through descriptive statistics, we identified that, although there are difficulties, there is a general student perception that their spaces used during ERT were adequate to their needs. In addition to students responding relatively well to the restrictions imposed by social distancing, both psychologically and socially, the technological environment was important for good achievement in teaching and learning activities.
