The inclusion of students with Intellectual and Developmental Disabilities (IDD) in Higher Education (HE) is a social and educational imperative, ensuring diversity and equity in learning opportunities. Within this context, the Individual Multidisciplinary Studies Program (PIEM) emerges as an innovative model of inclusion, promoting the full inclusion of these students into the regular classes at a public HE institution in Portugal. To understand the effectiveness of the PIEM, this qualitative study, designed as a case study, explored the perspectives of students with IDD and their mentors. Through interviews and document analysis, the research unveiled the benefits and challenges of the program, weaving a rich panorama of its relevance in the academic and personal trajectories of students with IDD.

The research findings highlight the crucial role of PIEM in promoting inclusion, supported by pillars such as:
i) Individualized Support - personalized and focused support, tailored to the specific needs of each student, considering their strengths and challenges;
ii) Effective Mentoring - the involvement of experienced mentors who serve as facilitators in the students' journey, helping them adapt to university life to developing autonomy and self-confidence;
iii) Peer Collaboration - encouragement of interaction and collaborative work between students with and without IDD, promoting mutual respect and the construction of an inclusive university community.

The conclusions of this study offer valuable contributions to the improvement of inclusive practices in HE, with an emphasis on:
i) Training of Qualified Mentors - implementation of comprehensive training programs for mentors, equipping them with the necessary skills and knowledge to effectively support students with IDD;
ii) Adequate Access and Resources - ensuring accessible physical and technological infrastructure, adapted teaching materials, and other resources that facilitate the full participation of students with IDD in academic activities;
iii) Inclusive Culture - fostering a welcoming and receptive university environment that embraces diversity, combats stereotypes, and promotes respect for individual differences.

By shedding light on the experiences and outcomes of PIEM, this study contributes to the construction of a more inclusive and equitable HE, where all students, regardless of their capabilities, should thrive and achieve their academic and personal potential.
