Background: Inclusive research with people with intellectual disabilities is growing internationally but with few studies examining its feasibility. Methods: In undertaking a national study exploring what life was like in Ireland for people with intellectual disabilities, a community of practice was developed involving a core group of co-researchers: five people with intellectual disabilities, four university researchers and three service support staff. An additional cadre of 15 co-researchers with intellectual disabilities was recruited to undertake data gathering and analysis with 23 focus groups involving 168 participants. The research experience was documented through oral feedback, progress reports, minutes and a project review. Results and Conclusions: The key learning is documented arising from the setting up of an inclusive advisory group and implementation of each of six research steps. The study demonstrates feasibility and the added value of university co-researchers recruiting and developing skills together with co-researchers with intellectual disabilities. Topics for further research and development are identified.
