The Policing Evaluation Toolkit

About this Toolkit

This is a practical Toolkit which brings together evaluation design and implementation strategies that can be used by practitioners and researchers alike to ensure evaluations are designed in such a way that strong statements of causal impact can be made.

Evaluation and evidence-based policing
Evaluation is a key component of an Evidence-Based Policing (EBP) approach in which police officers and staff create, review and use the best available evidence to inform and challenge policies, practices and decisions.  The College provides a range of resources to support people across the service to understand and use evidence-based approaches.

What is evaluation?
Evaluation is a set of methods and tools which enable officers and staff to answer the questions 'Did it work?', 'To what extent did it work?', 'Why and how did it work?' But not all evaluations are the same: the quality of design and execution matters.

Rigorous planning and execution are two of the hallmarks of effective evaluation. In this Toolkit, you'll learn the methods of evaluation and how to apply them in your own context. By using this Toolkit, police forces around the country will be better able to create, share and use evidence of what works, and test out new, evidence-based initiatives with a robust evaluative framework in place.

So how can the evaluation toolkit help me?

  • The Toolkit provides a framework for knowing whether an intervention is effective or not, and for assessing strength of the impact.
  • Effective evaluation can save time, resources and money. By using the Evaluation Toolkit to test new interventions, policies or tactics locally, knowledge of effective practice can be built up and used to inform decision-making.
  • Effective evaluation guides future action; the investment of time and effort in designing and running an evaluation pays off repeatedly in better decisions about the deployment of resources for maximum public benefit.


We're keen to receive feedback from users of the toolkit to help us develop the content and ensure it is as useful as possible. If you have any comments, please get in touch with us via email: research@college.pnn.police.uk
