It is a Capacity Building support category. According to the NDIS Guide to Support Budgets, Capacity Building funding is designed to help participants build skills and independence, and is distinct from Core Supports, which funds day-to-day assistance.
This is different from Community Participation under Core Supports, which funds a support worker to help you take part in activities right now. Increased Social and Community Participation works towards a goal in your plan: building the specific skills and confidence to take part more independently over time. Progress is usually reviewed against your plan goals, so this support tends to be structured and time-bound, not ongoing in the same way as Core Supports.
If your plan is self-managed or plan-managed, you can choose any provider. If it is NDIA-managed, you need a registered provider like us.
