The CALMER Approach is an evidence-informed practice, focusing on building capable environments and co-designing therapeutic support as an alternative to traditional behaviour management, utilising knowledge translation to put theory into practice. CALMER is relational, co-designed, constructive and living model for building capacity and wholistically understanding human behaviour from the perspective of the relationship between emotions and interactions. It is culturally sensitive, neurodivergent affirming and respectful of diversity. CALMER is inclusive of all ages, genders, cultures and environments. CALMER is for everyone, regardless of disability or ability.
