People with intellectual disability should access support from mental health services in the same way as the general population, within a framework which is multi-disciplinary and catchment area-based. Team members should have appropriate training and expertise, and teams should be suitably resourced. Recommendations for the mental health of intellectual disability (MHID) model of service follow similar international models. It is imperative that MHID services capture the work they do, and use evidence-based practice. Guidance in this model is provided to work towards service provision which is person-centred, integrated and with a clear governance structure. There are a number of challenges in delivering mental health services for people with intellectual disability. Recruitment is a significant issue, as is the interface between mental health and social care, and intellectual disability and general adult services. Local and national leadership fostering a person-centred approach which ensures that service users are appropriately assessed and treated in a timely manner are key aspects in the provision of these services
