How do we build assessment tools that truly capture the complexity of sensory integration, and how do we use them meaningfully in clinical practice? In this opening session of CLASI's 2026 webinar series, Tricia Grady, Marco Leão, and Zoe Mailloux explore the development and ongoing refinement of assessment tools in Ayres Sensory Integration — with a focus on the Evaluation in Ayres Sensory Integration (EASI). Participants will leave with concrete clinical takeaways on how to interpret assessment profiles and translate findings into informed, evidence-based decisions at the point of care. Whether you're new to these instruments or looking to sharpen your clinical reasoning, this session bridges the science and the everyday realities of practice.
