Extension impact assessment

Understand whether your extension work is making a difference, and how.

We answer questions like

  • Is our extension work actually making a difference?
  • Are we seeing real practice change, and where?
  • What is driving impact, and what is not?
  • Who is benefiting, and under what conditions?
  • How do we demonstrate impact in a way that is credible and practical?

How it works

We provide a clear, evidence-based assessment of extension outcomes and impact. This involves bringing together multiple sources of data and insight to understand what has changed, who is benefiting, and why. We assess the contribution of extension activity to observed outcomes, recognising that behaviour change is influenced by many factors.

Our approach combines quantitative data with qualitative insight to build a well-rounded picture of impact in context. We focus on developing credible, practical impact narratives that reflect real-world complexity, using approaches that are proportionate and feasible.

Why us?

Our strength is in making sense of behaviour change in real-world systems, where outcomes are influenced by multiple factors and cannot be attributed to a single intervention. We focus on producing clear, credible insights that can be used immediately. This includes balanced judgements, practical implications, and communication that works for funders, stakeholders, and delivery teams.
