The Lee-Evans 3C Bahaviour Leadership Model

Model Overview The Lee-Evans 3C Behaviour Leadership Model for Education was developed by Kerry-Ann Lee-Evans, an educational leader and school middle leader working in the UK and Jamaica. Designed specifically for leadership implementation by Heads of Years and Assistant Principals at the year group level. Behaviour in schools is frequently addressed as a student-level problem through policies, sanctions, or isolated interventions. Such approaches often fail to produce sustained improvement because they overlook the central role of leadership decision-making in shaping behaviour and culture. The Lee-Evans 3C Behavioural Leadership Model reframes behaviour as a leadership outcome rather than a pupil deficit. The model proposes that sustainable behaviour improvement is shaped by three interdependent leadership domains: Choices, Chances, and Changes. Choices refer to the expectations leaders set, the standards they model, and the behaviours they tolerate or ignore. Chances represent the systems and structures that allow for support, inclusion, restoration, and meaningful opportunities for reset. Changes encompass consistency, accountability, and leadership follow-through that embed expectations into everyday practice and culture. The Lee-Evans 3C Behavioural Leadership Model is designed as an adaptable framework rather than a prescriptive programme. Schools apply the model within their own contexts, structures, and priorities, using it to interrogate leadership decisions rather than impose uniform practices. Implementation is intentionally structured over a one-year cycle, allowing leadership teams to introduce, embed, review, and refine practice in a sustainable manner. The model is particularly effective when applied at year-group or phase level, enabling leaders to examine behaviour patterns, consistency, and culture within defined cohorts before scaling across the wider school. Crucially, the model is cyclical rather than linear. Leadership approaches that emphasize choices without chances risk creating punitive cultures; chances without changes lead to inconsistency and chaos; and changes without clear choices result in confusion. Behaviour improves only when all three domains operate together. By making leadership decision-making visible, time-bound, and context-responsive, the Lee-Evans 3C Behavioural Leadership Model provides school leaders with a strategic framework for shaping behaviour, inclusion, and culture across whole-school systems.
