    The founder and sponsor of the Harris Federation, Lord Harris of Peckham, opened our first school in 1990. We have, over the past thirty years, implemented ideas and initiatives that have transformed the opportunities of pupils from working class and disadvantaged backgrounds. Harris academies are widely recognised as a force for social mobility. We are immensely proud of the role that our alumni are now beginning to play in the world and of what we believe our current generation of pupils will go on to achieve.


  • We now have over 50 schools educating more than 40,000 young people across London and Essex, and employ over 5,000 staff across our academies and head office. With the majority of our academies located in areas of high socioeconomic disadvantage, a high-quality education is key to the futures of the pupils we serve.

    As a provider of employment and education, we value the diversity of our staff and students, and all our staff are equally valued and respected. We are committed to providing a fair, equitable and mutually supportive learning and working environment for our students and staff.

    Our work will impact many generations to come, and our staff come from all backgrounds and walks of life, coming together to inspire young minds. We promote an inclusive culture that embraces the valuable and enriching contribution that all of our community make. We continue to be proactive in uplifting and supporting all voices at Harris., Harris has a strong culture of collaboration and best practice, with professional development and career planning at its centre. We invest in our staff with support, coaching, mentoring, and a wide range of top-quality training programmes delivered at every level., Our vision, from the start, has been to provide the structure and services needed for our schools to amount to more than the sum of their parts, and to free-up our teachers and leaders to focus on one thing and one thing only: the outstanding education of all their pupils. Our young people and communities are at the heart of everything we do. Our core mission has always been to close the educational gap between young people from disadvantaged backgrounds and their peers. Our ambition is one where every child in London, no matter their background, has equal access to high quality education, giving them the same opportunities and potential to succeed.

    We know there are many challenges facing our young people and the communities we serve, and that's why we need determined people like you to help us tackle those inequalities. Whilst each of our academies has their own unique cultures and values; as a whole Federation, we have four core values which are central to successfully achieving our vision: Excellence, Collaboration, Support, and Innovation. We are proud of our values because they guide us in how we work allowing us to achieve the best possible outcomes for our young people, communities, and colleagues.
