Liz Robinson


Liz’s motivation comes from a profound belief that schools can play a transformative role in children’s lives, but also in shaping whole communities. Social justice and wider change underpin her views that school simply must be about the whole child, the whole family and the whole community.

As the head at Surrey Square for many years, Liz used values as a key driver to redefine the purpose of the school and radically reshape the culture and approaches. She is exceptionally proud of how the school continues to develop and innovate.

Liz has deep expertise and a particular interest in capacity development and growing leadership. Her philosophy is based on a client-centred approach, actively empowering others into thoughtful action. She created The Big Leadership Adventure, our flagship programme supporting changemaker leaders in the sector.

Liz co-founded Big Education to be a place where those who believe in more radical change in the sector can come together; to collaborate, share, challenge and encourage one another. Let’s do more, together.

As mum to two young girls, Liz works flexibly to manage her role. She advocates for and seeks to model an authentic, reflective and relational approach to leadership.
