By Sheldon Glueck (Author), Graeme Newman (Introduction)

Sheldon Glueck’s Probation and Criminal Justice (1931), a collection of papers from world wide experts, stands as one of the earliest systematic examinations of probation within the American penal system. Published at a time when probation was still consolidating its place as a regularized judicial practice, the book sought both to describe the institution as it existed and to evaluate its possibilities as a rational and humane alternative to imprisonment. Glueck, already well known as a criminologist and later famed for his longitudinal studies on criminal careers, approached probation with the same empirical rigor and critical balance that defined his scholarship.
The work provides a historical account of probation’s origins, tracing its roots to the nineteenth-century innovations of John Augustus in Boston, and situates its emergence within the broader reform movements of the Progressive Era. By the early 1930s, probation had spread widely across American jurisdictions, yet it lacked the uniformity, resources, and professional standards necessary for consistent success. Glueck’s central argument was therefore twofold: probation held genuine promise as an instrument of rehabilitation and social reintegration, but its potential could only be realized through careful administration, adequately trained personnel, and an honest reckoning with its limitations.
To read Probation and Criminal Justice today is to encounter both a historical document and a surprisingly contemporary critique. The themes Glueck emphasized—the professionalization of probation officers, the dangers of excessive caseloads, the necessity of balancing rehabilitation with accountability—are still at the heart of debates over community supervision. The persistence of these concerns is a testament both to the enduring complexity of probation as a penal tool and to the prescience of Glueck’s analysis.
In this sense, the book is more than a relic of early twentieth-century criminology. It is a reminder that penal reform, however well intentioned, remains fragile unless supported by adequate resources, clear objectives, and sustained public commitment. Probation has advanced since Glueck’s time in terms of reach, sophistication, and legitimacy, yet the paradoxes he identified continue to shape its practice.
For scholars, practitioners, and students of criminal justice, this volume offers not only a window into the early years of probation but also a mirror reflecting ongoing challenges in community-based corrections. Glueck’s careful and critical study thus retains its relevance: a classic text that still speaks to the unfinished project of building a fair, effective, and humane system of criminal justice.

Community supervision, most commonly probation and parole, is a key component of correctional systems in every state and involves more people than are serving prison or jail sentences. At the end of 2020, almost 3.9 million Americans—or 1 in 66 adults—were on probation or parole in the U.S., compared with nearly 1.8 million in jails and state and federal prisons. Community supervision also presents a different set of challenges for policymakers and for the people affected by it than does incarceration. Individuals on probation and parole must earn a living, pay for housing, and care for their families, all while also attending to their own behavioral health needs. And, often, they must manage these responsibilities within the constraints of restrictive supervision rules. Failure to comply with these requirements can mean a return to incarceration, a process that in many states is a leading driver of prison admissions. To address the unique challenges of supervision systems, policymakers and other stakeholders need a greater understanding of policies that effectively support behavior change and manage probation populations. The Pew Charitable Trusts set out to help meet that need by reviewing state statutes affecting probation systems in all 50 states—which collectively supervise roughly four times as many people as do parole systems—and identified the extent to which states have adopted five key policies to help strengthen and shrink those systems. This review can provide a path for states and agencies seeking to improve their systems; offer better returns on public safety investments; and help lawmakers, practitioners, and advocates move their states toward a more evidence-based approach to community supervision. For each policy, Pew’s team established criteria—generally ranging from no adoption to the most efficient approach as demonstrated by research and current practices in the field—and used those to show each state’s existing strategy for addressing critical probation issues. For more information, see the policy descriptions, methodology (Appendix A), and list of state statutes (Appendix B). The five policies are part of a larger, comprehensive menu of supervision reforms that Pew and Arnold Ventures released in 2020, “Policy Reforms Can Strengthen Community Supervision: A Framework to Improve Probation and Parole.” That framework sought to be broad enough to account for the many differences in probation and parole systems throughout the country, such as that they may operate at a local, county, or state level, and, from state to state, can fall under the authority of the executive or judicial branch.5 But regardless of how a system operates, research suggests that these five policies can help states achieve key community supervision reform goals, including cutting the supervision population so that resources can be prioritized for higher-risk individuals, reducing instances of incarceration for technical revocations, and enabling mobility and employment

In March 2020, the Iowa Department of Corrections (IDOC) faced overcrowding and urgent health concerns. To address these issues, IDOC and other criminal justice agencies implemented measures to reduce the prison population and expand community-based corrections (CBC). These efforts included limiting revocations, expanding administrative review processes, releasing low-risk individuals, and increasing the use of telehealth and technology for supervision and programming. As a result, the prison population decreased by 13 percent within 6 months, while the CBC population increased by nearly 17 percent. Despite this increase, the average monthly revocation rate decreased by almost 40 percent between March 2020 and March 2021. In 2021, Iowa state leaders requested support from the U.S. Department of Justice’s Office of Justice Programs’ Bureau of Justice Assistance and The Pew Charitable Trusts to assess the impact of these changes on public safety and CBC operations using a Justice Reinvestment Initiative approach. This brief summarizes the findings from that effort.
