School 360 is lucky enough to have two Co-headteachers instead of one:

Andrea Silvain and Sarah Seleznyov

Andrea trained as a primary school teacher and has worked in education for 13 years. She was born in Newham and has spent her teaching career working in and around East London. Andrea is an advocate of The Arts and prior to teaching, she worked in Television and Theatre in diverse roles that have provided opportunities that enhance her skills as an educator and leader.
Andrea spent 5 years working at School 21 where she helped build and develop the Middle School as Deputy Head, specialising in wellbeing and embedding school culture.

Andrea’s drive and passion centres around social mobility, equality and the empowerment of young people. She thrives on developing those around her and being authentically engaged within all aspects of the community she serves.

Sarah has worked in London schools for over 25 years. She has been a Deputy Head, a School Improvement Consultant and a School Improvement Partner, across both primary and secondary schools. Before starting at School 360, she led the London South Teaching School Alliance, supporting a network of schools in South London with teacher development and school improvement and worked at The London Centre for Leadership in Learning, UCL Institute of Education, where she designed and led a range of research-informed programmes for school leaders and teacher enquiry projects. She has also worked for the Fischer Family Trust and the National Literacy Trust. She is a specialist maths tutor on the Let’s Think (Cognitive Acceleration) research project from King’s College University.

Sarah is a PhD student at Vrije Universiteit Amsterdam, and a Trustee of the Collaborative Lesson Research UK group. Sarah also sits on the British Curriculum Forum and is a member of the British Educational Research Association Council.

New school, new thinking events

About the events

School 360, Big Education’s newest school is proposing to think creatively about what primary education could and should look like.  Its first intake, in September 2021, will be Reception children, and it wants to ensure its early years approach is as creative and engaging as it can be for children and their families.

Stratford's groundbreaking school

School 21 is a state-funded, non-selective 4-18 school in Stratford, East London with a reputation for high standards, great teaching and an expansive and exciting curriculum

Expansive education

Big Education  is  an organisation that runs and supports schools, designs programmes and toolkits and provides thought leadership, for example Learning from Lockdown.

Giving every child a voice

Voice 21 exists to enable teachers and schools to provide a high quality oracy education so that all young people can find their voice for success.

Big Education’s new primary school has now opened its doors, and it is becoming something very special.

Our aim at Big Education is to develop a more expansive education, one that develops head (academics), heart (growth and well-being) and hand (creativity and problem-solving). To achieve this requires fresh thinking – about the curriculum, teaching and learning and ways of working. This school is already putting these ideas into practice and becoming a beacon of what a Big Education can look like.

The new primary school will not be isolated but part of a cluster of three Big Education schools in the area and already has an array of educational, creative and business partners – a Big Education Community. School 360 is rooted in the community, responsive to the full range of diversity of our local families and children, and provides a curriculum that skilfully weaves together head, heart and hand. We want young people to be taught how to solve problems in creative ways, and make a difference to the world around them. The school offers exciting opportunities and experiences for pupils that draw on the huge expertise and creativity of our partners.

The new primary school is part of a new development created by Vastint. Apartments, social enterprises and creative organisations will be housed alongside this two form entry primary school to form a thriving community – Sugar House Island.

The school is close to the Olympic site – now home to UCL, Sadlers Wells, the V&A and other extraordinary educational and cultural institutions who we already have strong relationships with.

The school will be part of a group of 3 Big Education schools in close proximity: School 21, a 4 to 18 school in the heart of Stratford with a strong reputation for innovation, and a new secondary school and sixth form that will open in 2023 next to Plaistow station.


The Head is about rich knowledge  – and how to apply it to  the world around us. It is about bringing subjects together to gain deeper meaning and it is about wrestling with big ideas and concepts.


The Heart is about well-being and growth. It is about every child having a sense of identity and developing the qualities that will be needed to thrive.


The Hand is about creativity and problem solving and the joy of the creative and performing arts.
