Introduction / Background
Clear, defensible evidence is the foundation of successful NDIS funding decisions yet the term “robust evidence” is often used without definition. What does “robust” really mean in the context of occupational therapy practice? This presentation explores how OTs can strengthen the quality of their evidence by drawing from multiple sources, ensuring that recommendations for therapy supports, assistive technology, and services are both clinically and contextually sound.

Method / Implementation
Using practical examples, the session will unpack different types of evidence including but not limited to self-reporting, clinical observation, task analysis, standardised assessments, report reviews, incident or progress data and how these interact to form a defensible picture of participant function. Attendees will examine how reliance on a single source, such as self-reporting alone, can limit accuracy and reduce evidentiary strength, and learn strategies for triangulating data to support robust reasoning.

Discussion / Outcomes
Through interactive discussion, participants will reflect on the hallmarks of high-quality evidence, how to balance qualitative and quantitative sources, and how to critically appraise their own assessment processes to ensure they meet NDIS expectations for “reasonable and necessary” justification.

Conclusion
Robust evidence doesn’t come from one measure, it’s built through thoughtful synthesis and clinical reasoning. By diversifying evidence sources and integrating them coherently, OTs can enhance the credibility of their recommendations and contribute to more consistent, transparent decision-making within the NDIS.
