Inclusive education remains a challenge to be embraced by the national educational system, and this challenge becomes even more pronounced when considering the access and participation of young individuals with intellectual disabilities (ID) in higher education. The present systematic review aims to delve into the scientific literature addressing the theme of the presence of students with ID in Spanish university classrooms. To achieve this, a thorough examination of 34 scientific articles published between 2012 and 2022 was conducted across the databases of Dialnet, RedALyC, SCOPUS, Web of Science, and Google Scholar. Through the analysis of the selected studies, a research trend regarding the inclusion of students with ID in Spanish universities is identified, and the results are summarized. These results indicate a disparity between the increasing response of Spanish universities to students with ID and the limited production of scientific literature on the subject. The review concludes by emphasizing the need to promote high-quality inclusive research processes within the university environment, with a focus on accessibility and equal opportunities for young individuals with ID in higher education.
