This article analyzes, under several dimensions, whether collaboration contributes to the production of high-quality scientific results. It examines the proportion of scientific quality (measured by impact and relevance) gained by ISI publications considering the presence of a particular form of collaboration. As an application case, this paper offers a micro-level analysis of the academic research groups (ARGs) of a technical university. Results indicate that there are positive and significant benefits in scientific

quality received by ARGs as product of international and inter-sector collaboration, and in a broader sense, from the presence of inter-institutional collaboration.
