Introduction

Over the last several decades, landmark studies have been conducted in the fields of sentencing and corrections that have influenced current practices, and provide insight into contemporary research questions. This body of research includes notable “firsts,” including the use of randomized controlled trials in community corrections settings to reliance on administrative data as a means to understand program effects to organizational studies to assess the role of key actors and the impact of the milieu on different individual-level outcomes. Other contributions included new approaches to services, programs, and/or interventions. These landmark studies are classics in our field, informing our current state of knowledge and setting the stage for future research studies.
