Since 1991 various disability support service data collections have facilitated the annual collation of nationally comparable data about disability support services provided under the National Disability Agreement (NDA) (most recently known as the Disability Services National Minimum Data Set (DS NMDS) collection). These collections obtained reliable and consistent data with minimal load on the disability services sector. Under the NDA, jurisdictional Disability Administrators were responsible for ensuring 'that DS NMDS information was comparable across all jurisdictions and years'. The DS NMDS collection materials (DAT 4) for the last year which data were collected under the DS NMDS are below.
