This research seeks to explore academics' perceptions of the importance and degree of implementation of the Standards and Guidelines for Quality Assurance in the European Higher Education Area (ESG) for internal quality assurance. It uses empirical evidence from Portugal, gathered via a questionnaire given to all university academics. Results show academics' perceptions of the importance and implementation of the ESG in their institutions to be quite positive. Nevertheless, academics tend to find the standards more important than effectively implemented. Furthermore, significant differences in perceptions emerge between groups of academics. This study intends to contribute to a better understanding of the implementation of quality management practices in universities, and the influence of the ESG in this process.
