Recognising Sammy’s need for emotional wellbeing support, we introduced him to the Thrive approach, a programme designed to address social and emotional development. We began Sammy’s support programme by identifying gaps in his emotional development which could then be targeted with interventions. For Sammy and many students like him, a focus on structured SEMH interventions helps them step back from the brink and sets them on the right course. And that has to be the most powerful evidence that a different approach to behaviour can be genuinely transformative.
