This paper addresses the issue of accessibility to written information in cultural spaces for people with intellectual disabilities (ID). The main goal is to present a process aimed at creating Easy-to-Read (EtR) texts. Two groups of participants with different levels of ID–moderate (N=7) and severe (N=7) –have been actively involved in the process of simplification of written resources within the Natural Science Museum, site in Trieste. We analyze the process that serve to create EtR textual resources functional for people with ID showing different levels of reading and comprehension abilities.By using an Inclusive Research approach, the contribution underlines the importance to include the voice of people with disabilities in the process of transformation of social and cultural spaces.
