Item Response Theory (IRT) has emerged especially as a solution to gaps and limitations on measurement and assessment presented on the application of then-predominant Classical Test Theory (CTT). Since then, an expressive evolution on its research and adoption have been observed. Although a 2019 publication performed a bibliometric study on the topic, it was restricted to the Web of Science database. Therefore, this research conducted an analog investigation on Scopus, also considered to be one of the top commercial databases, aiming to complement the mapping of the bibliometric landscape and to consolidate the grounds for a future systematic literature review. As a result, 8,872 publications have been retrieved (almost 8 times more than previously found on Web of Science), ranging between 1981 to 2022, with a non-interrupted growth in yearly scientific production since 1992, evolving from 108 to 896 papers in 2021. In terms of citations of the retrieved corpus, it is also observed a steady and progressive increase. It was conducted the analysis of yearly evolution of publications, citation evolution, h-index for the retrieved publications, authorship, co-authorship networks, main publications, most frequent journals, keyword network, authors affiliations among others, with pertinent tables and graphs.
