Students with co-occurring diagnoses often present with complex academic, behavioural, emotional, sensory, and social needs, making it difficult for teachers to know what to prioritize in the classroom. This professional development session will help teachers move beyond a diagnosis-first approach and use a practical, evidence-based framework to identify students’ most immediate needs, including safety, regulation, access to learning, communication, and skill-building. Participants will learn how to interpret behaviour through a needs-based lens, select appropriate classroom supports, and respond in ways that are proactive, compassionate, and focused on helping students participate meaningfully and build independence.
