What the evidence says
This page outlines various interventions within the Crime Reduction Toolkit aimed at improving policing practices through the establishment of standards, training, and the sharing of good practices. The toolkit integrates evidence-based approaches to enhance crime reduction efforts across different policing contexts. Evidence quality and effectiveness of each intervention may vary, with many backed by EMMIE ratings which consider the evidence's strength and implementation outcomes.
How it works
The intervention involves the connection and training of policing entities to promote best practices and comprehensive standards that facilitate crime reduction.
Implementation
Effective implementation requires commitment from policing organizations to engage in training and share experiences regularly.
