Welcome to the
BJS Federation of Schools

Our Story

Three Schools. One Shared Ambition.

The story of The BJS Federation of Schools is a story of partnership, transformation and the measurable difference that schools can make when they work together.

Today, Bonneville, Jessop and Stockwell Primary Schools form one successful Federation – three distinctive schools, serving their own communities, but united by a shared ambition for every child.

Our journey to becoming The BJS Federation began not with structure, but with a need for support and a belief that, by working together, our schools could be stronger.

The impact of that decision can now be seen in inspection outcomes, pupil achievement, leadership development and the sustained improvement of our schools.

Where Our Story Began

Before The BJS Federation was formed, Jessop and Stockwell Primary Schools operated together as The JS Federation.

At the time, the two schools were at very different points in their journeys.

Stockwell was facing significant challenges. The school had been judged Requires Improvement by Ofsted and was subsequently issued with a Warning Notice by Lambeth Local Authority, requiring significant and rapid improvement.

Jessop was in a different position. It had previously been judged Outstanding, but seven years had passed since that inspection and the school was approaching its next Ofsted inspection.

At this important point in the schools’ development, the JS Federation did not have the executive leadership capacity required to provide strategic leadership across both schools.

Support was needed.

A New Partnership

In 2019, Andrea Parker, Headteacher of Bonneville Primary School, was asked to provide executive leadership to Jessop and Stockwell, creating a new partnership between Bonneville and the existing JS Federation.

The initial purpose was clear: to provide strong executive leadership, increase leadership capacity and secure sustainable improvement.

However, what developed became much more than a temporary leadership arrangement.

Leadership expertise began to be shared across all three schools. Teachers learned from one another. Systems for monitoring standards became more rigorous. Curriculum development became increasingly collaborative and staff were given opportunities to contribute beyond their individual schools.

Most importantly, the partnership began to deliver improved experiences and outcomes for children.

Stronger Together

Over the following two years, the impact of working together became increasingly evident.

Leadership capacity strengthened, pupil outcomes improved and the three schools developed increasingly consistent approaches to curriculum, teaching, assessment, inclusion and school improvement.

Staff benefited from shared professional development and access to expertise across three schools rather than one.

Relationships between the school communities also developed, creating the foundations for something more permanent.

What had begun as a partnership created in response to challenge was becoming a strong and cohesive community of schools.

The experience established a principle that continues to define our Federation:

No school – and no child – should be left behind.

The BJS Federation Is Born

Following the success of the partnership, the decision was taken to establish a permanent Federation across all three schools.

On 1 October 2021, the JS Federation was formally dissolved and Bonneville, Jessop and Stockwell became one hard federation: The BJS Federation of Schools, operating under a single Governing Board and the executive leadership of Andrea Parker.

Federation was never about making three schools the same.

Each school retained its own identity, history and relationship with its community.

Instead, the Federation created the structure through which leadership, expertise and resources could be shared more effectively and all three schools could benefit from collective capacity.

The Impact: From Challenge to Sustained Improvement

The most powerful evidence of the Federation’s impact can be seen in the trajectory of its schools.

Stockwell: Requires Improvement to Strong Outcomes

Stockwell’s journey demonstrates what sustained school improvement can achieve.

The school entered the partnership having been judged Requires Improvement and subject to Local Authority intervention.

Through strengthened leadership, improved teaching, an ambitious curriculum, rigorous assessment and quality assurance, targeted professional development and consistently high expectations, the school changed significantly.

In September 2022, just three years after the partnership began, Ofsted judged Stockwell Good in every area.

The improvement continued.

By 2025, 95% of Stockwell’s Year 6 pupils achieved the expected standard in combined Reading, Writing and Mathematics.

This placed Stockwell among the strongest-performing schools locally and represented a remarkable change in outcomes from the school’s starting point.

Requires Improvement → Good in every area → 95% combined RWM

For us, this is what sustainable school improvement looks like.

Jessop: Sustaining and Strengthening Excellence

At Jessop, the challenge was different.

The Federation needed to ensure that a school with a historic Outstanding judgement continued to evolve, strengthen and provide an exceptional quality of education.

In January 2024, Jessop Primary School was judged Outstanding by Ofsted, recognising the impact of ambitious curriculum design, highly effective teaching, strong leadership and exceptional opportunities for pupils’ personal development.

The school’s 2025 Key Stage 2 outcomes provide further evidence of the strength and impact of its educational provision.

In 2025:

92% of pupils achieved the expected standard in Reading.
85% achieved the expected standard in Writing.
94% achieved the expected standard in Mathematics.
85% achieved the expected standard in combined Reading, Writing and Mathematics, compared with 62% nationally.
21% achieved the higher standard in combined Reading, Writing and Mathematics, compared with approximately 8% nationally.
Pupils achieved an average scaled score of 111 in Reading and 110 in Mathematics, demonstrating attainment well above national averages.

These results demonstrate the strength of Jessop’s curriculum and the effectiveness of teaching in securing high academic standards.

Particularly significant is the school’s success in ensuring that disadvantage does not become a barrier to achievement.

In 2025, 84% of disadvantaged pupils achieved the expected standard in combined Reading, Writing and Mathematics, compared with 85% of non-disadvantaged pupils.

This attainment gap of just one percentage point is particularly noteworthy and reflects the school’s commitment to equity, inclusion and high expectations for every child.

Jessop’s outcomes demonstrate that excellence is not simply about achieving high standards overall, but about ensuring that those standards are accessible to children from all backgrounds.

The school has also sustained particularly strong performance in Reading. In 2025, Jessop achieved the third-highest average Reading scaled score among Lambeth’s non-faith primary schools.

These achievements provide measurable evidence of a school that has not rested on its historic success but has continued to strengthen its educational provision through the Federation.

Jessop’s journey demonstrates that effective federation is not only about improving schools facing significant challenges. It is equally about sustaining excellence, strengthening provision and ensuring that every child has the opportunity to achieve exceptionally well.

Bonneville: Sustained High Performance

Bonneville’s role in the Federation has always been about more than sharing established practice. The school has continued to develop and improve while supporting improvement elsewhere.

In May 2024, Ofsted judged Bonneville Outstanding in every area.

Inspectors recognised the strength of its curriculum, teaching, leadership, behaviour, personal development and Early Years provision.

Pupil outcomes provide further measurable evidence.

In the 2025 Key Stage 2 assessments:

90% of pupils achieved the expected standard in Reading, with 33% at Greater Depth
94% achieved the expected standard in Writing, with 39% at Greater Depth
92% achieved the expected standard in Mathematics, with 53% at Greater Depth
90% achieved the expected standard in combined Reading, Writing and Mathematics, with 33% achieving Greater Depth combined

Bonneville’s combined outcome placed the school 3rd across the borough (excluding faith schools).

This sustained performance is particularly important to our Federation story.

School-to-school support has not required one school to compromise its own standards.

Instead, collaboration has strengthened the collective capacity of all three schools.

Two Outstanding Schools in Four Months

One of the clearest indicators of the strength of our shared approach came in 2024.

January 2024 – Jessop: OUTSTANDING

May 2024 – Bonneville: OUTSTANDING IN EVERY AREA

Two separate Ofsted inspections, undertaken within four months of one another, independently recognised the quality of education being provided within the Federation.

Both inspections highlighted features central to our shared model: ambitious curriculum design, strong teaching, effective leadership, high expectations and extensive opportunities for children’s wider development.

This external validation sits alongside the measurable improvement at Stockwell and strong academic outcomes across our schools.

The Power of Shared Leadership

Our impact is not measured by pupil outcomes alone.

One of the most significant achievements of the Federation has been the development of leadership capacity.

Rather than expertise sitting within individual schools, leaders increasingly work across the Federation.

Subject leaders collaborate on curriculum development. Teachers plan together, observe and learn from colleagues in sister schools. Senior and middle leaders contribute to improvement beyond their own settings, and professional development is designed collectively.

We have also created pathways for staff to progress into leadership.

Colleagues have developed from Teaching Assistants to Teachers, classroom roles into subject leadership, phase leadership, Assistant Headship, Federation-wide leadership and Head of School positions.

This creates something particularly important for long-term school improvement:

succession and sustainability.

We do not simply develop systems.

We develop people who can lead them.

2025

The strength of outcomes across the Federation is reflected not only in overall attainment but also in the performance of key groups of pupils.

The trajectory is clear.

The Federation has enabled us to improve where improvement was needed, sustain excellence where it already existed and build collective capacity across all three schools.

Beyond Academic Outcomes

We are equally proud that our success is not defined solely by test results.

Across our schools, children benefit from a rich programme of sport, music, the arts, trips, residential experiences, leadership opportunities and wider personal development.

Our approach to inclusion ensures that children with additional needs and those facing barriers to achievement remain at the centre of our work.

Our ambition is not simply to produce strong academic outcomes.

It is to develop confident, knowledgeable, resilient and socially responsible young people who are prepared for the next stage of their education and ambitious about their futures.

Rooted in Our Communities

While we share leadership, expertise and ambition, Bonneville, Jessop and Stockwell remain proudly individual schools.

Each has its own history, character and community.

That individuality matters to us.

Our Federation model is not about uniformity. It combines the strength and identity of individual schools with the capacity, expertise and opportunities available through a larger organisation.

Our children belong to their school – and their school belongs to something bigger.

Beyond Our Three Schools

The philosophy that created The BJS Federation continues to shape how we see our responsibility within the wider education system.

Our journey began because leadership expertise was shared to support schools at a critical point in their development.

We continue to believe that strong schools and strong leaders have a responsibility to contribute beyond their own boundaries.

Our leaders contribute to educational development and school improvement across Lambeth and beyond, sharing expertise in leadership, curriculum, inclusion, teaching and racial equity.

Our Executive Headteacher has held significant borough-wide leadership responsibilities, including leading Raising the Game: Achievement of Black Caribbean Pupils, establishing Racial Justice Champions and contributing to wider strategic educational leadership across Lambeth.

The principle remains the same:

When we know something makes a difference for children, we share it.

Our Story Continues

The BJS Federation did not begin as a finished model.

It grew from challenge.
It developed through partnership.
It succeeded through collaboration.
Its impact is demonstrated through outcomes.

From the challenges facing Stockwell and the former JS Federation, through the partnership established in 2019 and the creation of The BJS Federation on 1 October 2021, our journey demonstrates what purposeful collaboration can achieve.

We have seen a school move from Requires Improvement to Good and subsequently achieve 95% combined outcomes.

We have seen two schools independently judged Outstanding within four months of one another.

We have sustained exceptionally strong pupil outcomes while developing leadership capacity across three schools.

We are incredibly proud of how far our schools have travelled.

But our story is not finished.

As we enter our next chapter, our purpose remains unchanged:

to protect what works, continually improve what we do, develop exceptional people and ensure that every child in every one of our schools receives the education they deserve.

No school and no child should be left behind.

Three schools. One Federation. One shared ambition: excellence for every child.
