General terms

NDIS Participant Charter-  Steps out information on when you can expect decisions to be made by the NDIA and how long things should take. It is a service guarantee.

NDIS Partners are local community organisations that work with the NDIA to deliver the NDIS. Partners are based in the region in which you live. (Please note that there are key differences for children under 9 years of age and those aged 9-64). 

ARF: Access request form- You must fill this out to apply for the NDIS. Section 2 is for your supporting health professionals to fill out.  

Functional Capacity Assessment (FCA): a functional capacity assessment is usually completed by an Occupational Therapist or other Allied Health professional. It provides information about the impact of a person’s disability on their everyday life. It can strengthen the evidence required when seeking access to the NDIS or when a participant requires additional funding added to their NDIS plan due to a change or decrease in function.  



Categories of funding

Watch a video from NDIS Australia about support budget types. 


Plan management options

Self- managed

Self-management - when a participant manages their NDIS plan. This requires the participant to pay for services and then claim them through the portal. The participant will need to keep track of spending and the receipts.  

Plan- managed 

Plan management - when a 3rd party manages a participant's NDIS plan. Additional funding is included in the plan to cover these costs. The participant can use choice and control around the plan manager that they want.  

NDIS- managed/ Agency managed

NDIA managed - when the Agency works a participant. The participant can only access NDIA registered providers, and claims from the providers are sent directly to the NDIA.  

Review process

Internal review of a decision- previously known as an S100 or review of a reviewable decision. This can be applied when you are unhappy with the NDIA's decision. This must be made within 3 months of the final decision.  

Plan reassessment (Participant or agency initiated), previously known as an S48 review or Change of circumstances – A participant can request a plan reassessment if their current plan does not meet their needs or there have been significant changes in their function and the participant requires increased support. 

Administrative Appeals Tribunal (AAT)- If you are not happy with the outcome of your internal review, you can apply for the AAT, which results in an external review of the outcome.
