Breadth and Depth not Breadth vs Depth

James Haughton, CEO of Pestalozzi International, on why education systems need both programmes of breadth and programmes of depth - and how leadership development multiplies impact.

We Need Both

There is an important distinction in education strategy between programmes of breadth and programmes of depth.

Programmes of breadth focus on scale. They aim to reach as many children as possible. Universal primary education campaigns, infrastructure investment and teacher recruitment drives fall into this category. They are indispensable. Without breadth, opportunity remains always the privilege of a few.

Programmes of depth focus on intensity. Pestalozzi invests deeply in smaller cohorts over time, strengthening identity, resilience and leadership capability. We do not replace breadth. We complement it. We ensure that access translates into sustained contribution.

Programmes of breadth widen the doorway. Programmes of depth (like Pestalozzi's) strengthen those who will hold it open for others. A healthy education ecosystem needs both.

If we wait for universal access before investing in leadership development, we risk building a system without enough leaders to sustain and improve it.

Holding the door open for others

Sixty per cent of Pestalozzi alumni enter public service careers, with 6 out of 10 of those becoming educators. It is an outcome we highly value.

In Zambia, the pupil-to-teacher ratio in primary schools often exceeds 40:1, and in some rural districts it is higher still. Teacher shortages, particularly in rural and hard-to-reach areas, remain a persistent constraint on quality education. UNESCO and national education reports consistently highlight the need for more qualified teachers, especially in science and mathematics.

One teacher influences hundreds of children over a career.

If a teacher instructs 40 students per year and teaches for 25 years, they will directly shape at least 1,000 learners. Many teach far more. When that teacher carries resilience, ethical grounding and a belief in every child's potential, the reach multiplies.

This is the depth effect feeding the breadth effect.

Leadership development in childhood becomes national capacity building when graduates return as teachers.

What Pestalozzi Alumni Carry Forward

Pestalozzi alumni who become teachers do not simply deliver the curriculum. They carry forward the structure and values of the Leadership Pathway they experienced.

From Belonging, they carry an understanding of how stability and high expectations change outcomes. They recreate classrooms where children feel safe and capable.

From Growth, they carry resilience and self-belief. They understand that poverty is not just material; it is also psychological. They recognise how trauma and low expectations can quietly limit ambition. As educators, they respond not only with instruction but with encouragement and structured support.

From Active Citizenship, they carry systems awareness. They teach students how institutions function and how to participate responsibly in civic life.

From Leaders in Practice, they carry the lived experience of responsibility. They model agency because they have practised it.

This combination produces teachers who see themselves as shapers of citizens, not merely deliverers of content.

Alumni in Action: The Edulution Effect

One of the clearest illustrations of leadership depth strengthening system breadth is the partnership between Pestalozzi alumni and Edulution, a social enterprise delivering tablet-based mathematics and literacy instruction in underserved schools.

More than 40 Pestalozzi alumni have worked as coaches and leaders within Edulution. Many began as classroom facilitators and progressed to centre leadership, regional coordination and educator training roles. Collectively, they have supported thousands of learners across Zambia and neighbouring countries.

Each alumnus working within Edulution does more than teach mathematics. They model resilience, structure and high expectation. They carry forward the Leadership Pathway they experienced themselves. They understand how to foster a sense of belonging in a classroom. They know that poverty is not only material but psychological, and they recognise how low expectations can quietly limit aspiration. They bring systems awareness, accountability and problem-solving into daily practice.

If each alumnus working through Edulution reaches even 200 learners per year through direct and supported instruction, the cumulative reach across 40 alumni quickly exceeds 10,000. That is the multiplier effect of leadership depth feeding national breadth.

This is what happens when childhood leadership development meets national education needs. Graduates not only succeed personally. They strengthen institutions. They reinforce learning ecosystems. They extend quality education into rural and resource-constrained environments.

Edulution is not an isolated example. It is evidence of how programmes of depth - like Pestalozzi's - can supply systems of breadth with capable, values-driven educators.
