In recent years, research has been taking an important role in Peru. There are different sources of funding for research projects, research internships, the publication of scientific articles, scholarships for postgraduate studies, among others. This importance of research has resulted in an interest in being able to measure and compare universities according to their scientific production. One of the main factors to be used to make these comparisons is the number of articles published and indexed in SCOPUS. However, this measure is not entirely fair, since it is not equitable to compare a large university with a small university since large universities have more human resources to publish scientific articles. Seeing this reality, in the present work, we present a comparison of scientific production in Peruvian universities, taking into account the size of the institutions. Among the results obtained, we can observe a change in the ranking of small universities that invest heavily in research.
