This chapter describes tools for researchers to address the tasks of problem definition, measurement, causal processes, and generalization. We begin with an extended example of developing practice-based evidence in community-based youth justice organizations in New York City. Then we expand on the four basic dimensions of research tools and discuss how they might be applied to develop practice-based evidence on an important and evolving intervention in policing.
