We fund NDIS supports that will be, or are likely to be, effective and beneficial for you, having regard to current good practice. This means we consider if there is evidence that the NDIS support is effective and beneficial for someone with similar disability support needs.
For example, we may already have information about whether the support is widely accepted to suit someone with similar disability support needs.
The primary source of evidence we rely on, and give the greatest weight to, is evidence from sources that are reliable and recognised. This includes published and refereed literature, and any consensus of expert opinions.
If there is no evidence to show an NDIS support is reasonable and necessary, we won’t fund the NDIS support.
You can find the types of evidence we need on the NDIS website , and in our guidelines.
