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To read Probation and Criminal Justice today is to encounter both a historical document and a surprisingly contemporary critique.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

Many states have enacted comprehensive justice system reforms to reduce incarceration and community supervision in order to focus funding more on people at higher risk of reoffending and invest in strategies to achieve better outcomes for people and communities. Many policy reforms have been spurred by significant growth in the number of people on community supervision. According to a 2018 Pew Charitable Trusts chartbook, probation and parole populations nationwide grew 239 percent from 1980 to 2016 (Horowitz, Utada, and Fuhrmann 2018). Notably, community supervision populations peaked in 2007 and then fell 11 percent between 2007 and 2016. 1 To date, research on the impact of states’ community supervision policy changes has not kept pace with the rate at which they have been enacted, leaving policymakers and practitioners with a knowledge gap on which reforms have made a difference and why. The Urban Institute and the Crime and Justice Institute (CJI) assessed policies reforming probation sentencing in two states, Louisiana and Georgia, to understand their impact on people who are supervised and on outcomes including revocation and successful completion. Reforming probation sentencing is one way to ensure scarce resources are prioritized for supporting and monitoring people when their risk of failing supervision is highest, not for long periods after this risk has declined. Research has shown that supervision is most effective when it focuses on people who are at higher risk of reoffending and that recidivism rates drop precipitously after the first year of supervision (Alper, Durose, and Markman 2018; Andrews and Bonta 2010). A statutory reduction of the length of probation supervision terms can be a direct way to reduce the number of people under community supervision. When implemented consistently, probation sentencing reform may yield more reliable reductions of the supervised population than reforms that depend heavily on changing supervision practices. And by limiting how long supervision resources can be expended on people at low risk of failure, these reforms can yield significant gains in cost savings and community safety. In contrast to other community supervision reforms (such as earned discharge policies) that require people to incrementally earn time off potentially lengthy sentences at the back ends of their terms, probation sentencing reform establishes upper limits that apply uniformly to entire categories of people at the front ends of their terms. Despite these potential benefits, wholesale reductions of probation sentence lengths are uncommon. States’ strategies for reducing probation sentences have varied: some have shortened all probation sentences for certain offenses by reducing the maximum probation sentences allowed for those offenses, whereas others have simply granted judges the flexibility to impose shorter sentences than the maximums. Meanwhile, some states have used creative strategies to establish a presumption of shorter probation terms without changing sentencing requirements. These strategies blend front-end reductions of sentences with mechanisms similar to earned discharge policies that enable early release, but they also grant courts and supervising agencies discretion to extend those sentences at the back end because of noncompliance with supervision terms. For this reason, any assessment of the impact of probation sentencing reforms must consider the details of how they have been implemented and the extent to which discretion is allowed. Urban and CJI assessed implementation and analyzed outcomes of different approaches in Louisiana and Georgia. In 2017, Louisiana’s Senate Bill 139 eliminated the one-year minimum for all probation sentences and reduced the maximum sentence for felony probation from five to three years for a first, second, or third conviction for a nonviolent, non-capital felony. Approximately 89 percent of new probation starts in 2018–19 were for nonsex, nonviolent offenses. The policy allows judges to extend probation terms up to five years for people who do not comply with supervision conditions. The law affects everyone sentenced to probation as of November 2017. Also passed in 2017, Georgia’s Senate Bill 174 established two mechanisms for reducing probation sentence lengths. First, it requires that a probation sentence for any first-time felony conviction with a straight probation sentence (with no prison time) include a behavioral incentive date (BID) of three years or less, at which point the Georgia Department of Community Supervision (DCS) must file a petition to terminate probation if the person has not been arrested for anything other than a nonserious traffic offense during their probation term, has complied with the conditions of supervision, and has paid all restitution owed. About a third of the felony probation population from July 2017 to December 2020 was eligible for BIDs.2 Second, it makes early termination of probation available to anyone convicted of certain nonviolent felony offenses who has been sentenced to three years or more and who has not previously had their supervision revoked. The law requires DCS to file a petition for early termination for anyone who has completed three years of supervision and has not been arrested for anything other than a non-serious traffic offense, has complied with the conditions of supervision, and has paid all restitution. Courts may accept or reject BID petitions and early termination petitions at ends of their terms, probation sentencing reform establishes upper limits that apply uniformly to entire categories of people at the front ends of their terms.

In 2015, Rhode Island had the country’s second-highest probation population rate, with high probation revocation rates and lengthy probation terms contributing to an increasing prison population. To address these challenges, Rhode Island requested support through the Justice Reinvestment Initiative (JRI). As a result of JRI, Rhode Island amended the superior court’s Rules of Criminal Procedure and Sentencing Benchmarks in 2016, limiting probation periods for nonviolent offenses to 3 years and allowing for early termination of probation for people satisfying specified requirements. Subsequently, 6 JRI bills were passed in 2017. Among other things, these new laws and amendments to the superior court’s Rules of Criminal Procedure and Sentencing Benchmarks created policies that centered on reducing the prison population, launching a diversion program with an alternative to traditional conviction and sentencing, and screening cases for eligibility for early discharge from probation. This brief highlights the results of these measures.

In 2016, Georgia used the Justice Reinvestment Initiative (JRI) to focus on community supervision, as the state had the highest rate of adults on probation in the country. The JRI analysis showed that Georgia’s large probation population was due to widespread use of probation sentences for misdemeanor offenses, as well as lengthy felony probation sentences that were used in lieu of and in addition to prison sentences. Additionally, an estimated 50,000 people in Georgia had been on supervision for more than 2 years, despite the risk of recidivism dropping by half after an individual’s first year on supervision. In 2017, the governor signed Act 226, codifying the JRI policy framework. It featured policies to reduce lengthy probation terms and large probation caseloads, enhance the cost-effectiveness of responses to probation and parole violations, and improve the handling of legal and financial obligations for people on felony probation. This brief explores the effects of this legislation.
