National Ability Supports System (NASS)

The National Ability Supports System (NASS) captures information about disability service use and need to aid the planning, development and organisation of disability services in Ireland.  

How NASS data is collected

Data collection for the NASS is carried out via an online web-based system (NASS LINK).

If your service provides disability funded services, it is very important that you participate in the NASS so that there is a complete overview of the service use and need of persons with disability in Ireland.

To participate in the NASS, please request training on NASS LINK by contacting:
