In 2024, HIQA conducted a scoping review to inform standards for assessment of need to understand current systems and developments in the area of assessment of need. This paper describes both the national and international systems for assessment of need, and sets out current best practice and areas for consideration for Ireland from the approaches taken in other countries. The aim of this research is to inform next steps in relation to policy direction for assessment of need. This will inform the need for national standards for this area, so that any standards developed have the maximum benefit for people with disabilities and their families.
