The School Leader Inventory
Education is calling for a new breed of leader
The School Leader Inventory (SLi) is a suite of resources to help you accelerate development, improve performance and maintain the well-being of critical leaders in your school.
The framework and online diagnostic are
FREELY AVAILABLE TO ALL SCHOOLS
It puts you in charge of the pace and implementation of behavioural change by helping to develop a shared vocabulary for leaders and builds internal capacity to support your ongoing professional development, self-evaluation and school improvement agendas.
Train in-house staff as resident facilitators and build your school's internal leadership capacity
Schools that have adopted and used the SLi have seen it drive and accelerate school improvement, develop authenticity in their school self-evaluation and improve external inspection ratings.
Equip your leaders with the behaviours they need

42% of school leaders almost always believe in themselves as a leader but nearly 10% rarely or never do

Only 29% of school leaders are secure in their own self-worth as a leader in almost all situations
The SLi framework identifies the most relevant behaviours for school leaders with a particular focus on how they contribute to authentic, evidence based school self-evaluation and improvement. Sharing the vocabulary and behavioural definitions will help to develop consistent and congruent behaviour in your leaders that will support them as they tackle the current challenges in education.
