School improvement is built by individuals

We often overestimate the impact of big initiatives and underestimate the power of small improvements repeated over time.

Over my years in schools I have spent many hours participating in teaching teams collaborating on the design of a lesson or unit. What always sat with me wasn't the lesson or plans themselves so much, as the quality of the professional conversation taking place around it.

As they worked, teachers were discussing where students might struggle, debating the most effective examples to use, building on one another's ideas and sharing strategies that had been successful in their own classrooms. There was a genuine sense of curiosity in the room, coupled with a collective commitment to improving outcomes for the students they teach, even though these planning sessions frustratingly always seemed to go over the allotted time. If you've ever sat in one, you'll know exactly what I mean.

It made me reflect on how often we talk about school improvement in terms of major initiatives, strategic plans and system-wide change, when so much of the work that actually improves learning happens in quieter, less visible ways.

Improvement is often built through hundreds of small decisions made every day by teachers and school leaders who are willing to learn from one another, refine their practice and remain focused on what will make the greatest difference for students.

These moments rarely attract much attention, yet they are often where the most meaningful growth occurs.

For school leaders, I think there is an important lesson in this. While formal recognition certainly has its place, some of the most powerful encouragement can come from simply noticing and acknowledging the behaviours that contribute to a strong professional culture. A teacher who risks sharing an idea, asks a thoughtful question, supports a colleague through a tough day or experiments with a new approach is helping to move the work forward, and those contributions deserve to be recognised.

What we notice tends to grow. When leaders consistently acknowledge the small actions that strengthen practice, collaboration and learning, they reinforce the very culture they are trying to build.

Who is someone in your team who quietly made things better this week, and have you told them?
