Abstract
Despite their centrality to police legitimacy and operational effectiveness, formal education and training remain under-researched and conceptually inchoate topics. This paper addresses this gap through a scoping review of academic literature published between 2004 and 2023. It systematically maps publication patterns, methodological approaches, disciplinary orientations, and topical and thematic foci to assess the range and character of existing research. The findings reveal key trends and blind spots, particularly regarding the design, delivery, and evaluation of instruction. By contextualizing these patterns within broader transformations in policing, the paper offers a foundation for future inquiry and more evidence-based approaches to officer development.
Introduction
As the most visible agents of the criminal justice system, police play a pivotal role in modern societies. Tasked with crime prevention, law enforcement, and community service, their responsibilities have expanded significantly alongside a rapidly evolving social, legal, and technological landscape. Accompanying conventional tasks like patrolling, responding to calls, filing reports, and conducting investigations, officers are increasingly expected to act as problem-solvers, knowledge workers, and community mediators. This includes managing mental health crises, supporting victims, de-escalating conflict, handling digital and cyber-related crime, and addressing broader social challenges like substance abuse and homelessness (Loftus, 2012; Lum and Koper, 2024; Skogan, 2006). At the same time, they remain responsible for ensuring the safety of themselves, their colleagues, and the public, while fulfilling specialized functions related to public engagement, assisting vulnerable populations, and crime analysis and intelligence gathering. These cross-cutting demands make the acquisition and upgrading of skills, knowledge, and ethical standards essential for effective policing.
To meet these challenges, formal education and training, complemented by informal occupational socialization, represent institutionalized mechanisms through which police develop the competencies, expertise, and values required to execute their professional duties. While they frequently overlap, education seeks to cultivate analytical reasoning, ethical judgment, and critical thinking to broaden intellectual horizons and encourage reflective practice. Training, by contrast, emphasizes technical proficiency, procedural knowledge, and the acquisition of discrete skills for immediate operational use. Together, they constitute the foundation of police professionalization, a process that includes both formal instruction and the broader sociocultural and organizational dynamics through which officers are shaped and acculturated into the norms, expectations, and practices of law enforcement (Chan et al., 2003; Fielding, 2023). 1 Because they serve to enhance institutional performance and instil key occupational values and standards, formal education and training are essential to the ongoing legitimacy of law enforcement. Their significance has become increasingly pronounced amid growing public scrutiny as incidents of police misconduct have sharpened calls for transparency, accountability, and reform, underscoring the pressing need for robust and credible professionalization strategies (Walsh and O’Connor, 2019).
Despite the centrality of education and training to law enforcement’s public image and operational efficacy, research in this area remains comparatively diffuse. Although substantial work exists on police culture, community relations, use of force, and technological adoption, studies of formal instruction, whether delivered in academies, universities, or workplace settings, have yet to form a coherent field of inquiry (Mazerolle et al., 2014; Neyroud, 2011). Reflecting this fragmentation, existing reviews tend to focus on particular elements of the topic, including emerging issues and national reform efforts (Bartkowiak-Théron, 2019), the role of higher education in police professionalization (Paterson, 2011), and the design and effectiveness of recruit training programmes (Belur et al., 2020). While offering valuable insight, these syntheses illuminate only portions of a broader and more varied research landscape. The present study responds by examining the full range of peer-reviewed scholarship on police education and training, clarifying the field’s scope, recurring emphases, and areas where knowledge remains underdeveloped.
To meaningfully assess how education and training shape police development, it is important to situate them within the broader ecology of professionalization. This review draws on ecological systems theory (Bronfenbrenner, 1979), which emphasizes the nested and interdependent relationships between individuals and their social environments, and on occupational socialization research (Van Maanen, 1973), which examines how professional norms and behaviours are learned through organizational experience. Together, these perspectives frame police learning as a dynamic interplay among multiple levels, including individual dispositions, instructional design, institutional norms, and organizational culture. These layers interact to shape how instruction is delivered, internalized, and translated into practice. Although the review does not empirically test this framework, it underscores the importance of integrated conceptual models for capturing the complexity of officer development.
Against this backdrop, the present article offers a comprehensive overview of the research landscape to establish a clearer foundation for subsequent scholarship. It catalogues peer-reviewed studies on police education and training published over the past two decades, with particular attention to contributions from Australia, Canada, the United Kingdom, and the United States. By analysing established and emerging patterns regarding research output, methodologies, disciplinary orientations, and topical and thematic foci, the review clarifies how the field has evolved and where scholarly attention has clustered or remained limited. As this first structured synthesis of this literature, its findings carry important implications for both scholarship and practice, supporting evidence-based decision-making and more successful approaches to helping officers meet the demands of contemporary policing.
Methods
This study employed a scoping review methodology to rigorously map peer-reviewed research on police education and training. Following the framework outlined by Arksey and O’Malley (2005), the review involved five stages: identifying the research question, searching the literature, selecting relevant studies, charting the data, and collating and summarizing results.
Accordingly, the review asked: what is the substantive, thematic, and methodological character of academic work on police education and training? Given the kaleidoscopic nature of existing scholarship (Norman and Fleming, 2022), the absence of field-spanning overviews impedes analytical synthesis, strategic exploration, and evidence-based decision-making. Without a solid foundation, scholars, practitioners, and policymakers face barriers in identifying research gaps and advancing professional development within police services.
To identify relevant sources, a systematic search was conducted using Web of Science, a widely recognized database that indexes leading peer-reviewed journals across the arts, humanities, and natural and social sciences. While platforms like Google Scholar and ProQuest offer broader coverage, Web of Science was selected for its stringent indexing criteria and consistent metadata, which enhance search precision and support transparency and replicability. Relevant papers were identified by searching titles and keywords using iterative combinations of: ‘police’ or ‘law enforcement’ or ‘officer’ and ‘education’ or ‘training’. This occurred in April 2024.
To be included, research needed to meet several criteria.
First, only English-language publications were analyzed due to resource constraints associated with translation.
Second, the review focused on formal policing agents and the institutionalized transmission of knowledge. 2 Accordingly, despite their significance, studies of private security, civilian auxiliaries, support staff, or informal learning processes (e.g., peer feedback, occupational experience) and police culture, understood here as the complex of unofficial norms and tacit rules that shape officers’ identities and orientations (Reiner, 2010), were excluded.
Third, the sample was limited to research from Australia, Canada, the United Kingdom, and the United States. These countries were selected due to their shared liberal-democratic political cultures, common law traditions, and broadly similar policing and post-secondary education systems. Each also contributes substantially to peer-reviewed, English-language scholarship on the topic and has faced parallel debates around police legitimacy, accountability, and professionalization (Bayley, 1990; Waddington, 1999). Broadening the scope to include countries with different legal foundations, governance structures, and less accessible literature would have hindered synthesis.
Fourth, only studies published between January 1, 2004, and December 31, 2023, were included. This timeframe reflects the rapid evolution of policing institutions, technologies, and societal expectations during this period.
Finally, only peer-reviewed journal articles were selected to ensure methodological transparency and alignment with scholarly standards. While this excludes practitioner-oriented texts, curricular materials, and policy reports, their potential value is acknowledged in the discussion. Future reviews might incorporate such sources to develop a more holistic understanding of the research literature.
Using the specified search terms, 2646 publications were initially identified. After screening, 1999 were excluded for not meeting the inclusion criteria: 1121 fell outside the publication years of 2004-2023; 436 were not peer-reviewed articles; and 442 did not pertain to research from Australia, Canada, the United Kingdom, or the United States. The titles, abstracts and, where necessary, full-texts of the remaining 647 publications were then independently reviewed to exclude those unrelated to formal education or training and members of law enforcement. This yielded a final sample of 339 articles (see Figure 1). PRISMA flow diagram of the identification process for sample articles.
To identify established and nascent trends, the research literature was methodically examined. This involved summarizing results concerning publication patterns, disciplinary orientation, methodological approach, and research design. Methodological classifications were initially based on author descriptions, drawn from abstracts, keywords, and methods sections, but were refined through close reading and reviewer judgement to ensure accuracy and consistency. For example, studies were categorized as quasi-experimental if they met relevant criteria (e.g., the use of comparison groups or measurable interventions) even if not explicitly labelled as such by the authors.
An open-coding strategy was used to categorize studies by topical and thematic focus. Publications were reviewed to identify recurring issues, methods, and conceptual orientations. The depth of review varied depending on the information required to apply each code, consistent with scoping review methodology (Levac et al., 2010). This process was inductive and interpretive, allowing categories to emerge from the data without imposing a predefined framework (Saldaña, 2021). Topical focus referred to the surface subject (e.g., procedural justice, mental health training, use of force), while thematic focus captured broader aims, such as evaluating training, documenting instruction, exploring officer perceptions, or theorizing professionalization. Codes were refined through constant comparison and recursive revision to ensure coherence and consistency across cases.
Results
Research output
Between 2004 and 2023, 339 peer-reviewed articles were published, averaging 17 per year. As illustrated in Figure 2, output fluctuated significantly, from a low of 3 articles (2005 and 2008) to a peak of 56 (2021). Overall, publication volume rose substantially, with the annual mean increasing approximately fivefold between 2004 and 2013 (M = 5.6; SD = 1.8) and 2014-2023 (M = 28.3; SD = 18.5). While this review cannot definitively explain this growth, particularly the spike in 2021, possible contributors include heightened focus on police reform, the influence of global protest movements like Black Lives Matter, and shifts in research funding. Further investigation is needed to clarify these dynamics. Articles published per year.
Methodological orientation and research design
Contrary to claims that policing research is overly theoretical or anecdotal (Harris, 2012; Perez and Shtull, 2002), studies on education and training were predominantly empirical. Most employed statistical methods including regression analysis, randomized control trials, and quasi-experimental designs to evaluate training outcomes and program effectiveness.

Despite well-documented challenges to implementing experimental designs in policing, half of the publications (50.4%; n = 171) relied on, among others, randomized control trials, interrupted time series studies, propensity score matching or difference-in-differences analysis. 3 This apparent contradiction reflects a broader shift. Although historically underutilized, experimental and quasi-experimental approaches have gained traction, particularly in appraising instructional interventions.

Research topics
The review also assessed the topical focus of research, recording characteristics of instructional efforts including their type (education vs training), timing (pre-service, field, or in-service), and content (e.g. procedural justice, use of force).
Concerning the broader emphasis of professionalization, most studies (93.2%; n = 316) focused on vocational training, emphasizing the transmission of technical skills and procedural knowledge. A smaller share (5.9%; n = 20) explored formal education aimed at intellectual development and critical reflection. Only 0.9% (n = 3) addressed both. Although education and training can overlap or occur in the same settings (e.g. academies, universities), studies were coded based on the type and purpose of knowledge prioritized, not institutional context. Notably, few studies adopted integrated frameworks that consider how instructional content, delivery, and outcomes interact across organizational and individual levels.
Studies were also coded by career stage. The majority (n = 194; 57.2%) addressed in-service instruction for veteran officers provided via workshops, scenario-based training, online courses, and classroom delivery. Pre-service instruction at academies or universities accounted for 36.6% (n = 124). A smaller number (4.4%; n = 15) examined multiple career stages, while field training for probationary officers was addressed in just 1.8% (n = 6). This career-stage segmentation reflects a broader tendency to treat components of learning in isolation, rather than as part of a cumulative, relational process shaped by overlapping institutional, cultural, and pedagogical forces.
Examining instructional focus revealed an array of topics. While 28.3% of articles (n = 96) addressed education and training in general, most (n = 245; 72.3%) focused on specialized instruction regarding particular skills or practices. Of these, 64.1% (n = 157) emphasized the ‘guardian’ model of policing, centred on community engagement, problem-solving, and citizen protection (Stoughton, 2016), while 35.9% (n = 88) prioritized imparting ‘hard’ skills aligned with operational policing, crime-fighting, and hierarchical models of command-and-control typical of the traditional ‘warrior’ mindset.
Publications on community-oriented policing addressed both longstanding and emerging concerns. Crisis intervention and mental health training were most prevalent (n = 50; 31.8%), reflecting growing reservations that police interactions with individuals in crisis may erode public trust and strain departmental resources (Wood and Watson, 2017). Other leading topics included diversity and procedural justice (n = 31; 19.7%), addiction and overdose intervention (n = 22; 14.0%), officer stress and well-being (n = 23; 14.6%), victim support related to sexual or intimate partner violence (n = 21; 13.4%), and ethics and misconduct (n = 5; 3.2%). Their prevalence underscores a growing recognition of formal education and training as vehicles for de-escalation, cultural literacy, professional integrity, and improved police-community relations (Schlosser et al., 2015). Conversely, research on crime control and enforcement-oriented policing emphasized traditional paramilitary training. Key topics included critical incidents, firearms, and use of force (n = 28; 31.8%); physical fitness (n = 29; 33.0%); and criminal intelligence and related activities (e.g., interrogation, behavioural analysis, and deception detection; n = 17; 19.3%). Each category also contained several topics coded ‘other’ due to limited representation. 5

Thematic foci
Analysis of the literature’s primary foci and conclusions yielded six core themes, reflecting the distribution of scholarly attention and concern. These themes capture the field’s evolving contours and offer a panoramic view of its current theoretical and empirical foundations.
The leading theme, Outcomes and Effects, appeared in 59.3% of publications (n = 201). Studies in this category employed empirical data to assess the results of various police education and training initiatives, focusing on the nature, magnitude, and durability of their impacts. To contextualize these findings, each study’s methodological rigour and capacity to support valid inferences about causal relationships were determined using established criteria including the presence of a comparison or control group, baseline measures, and clearly defined outcomes. 6 Randomized control trials and other counterfactual designs are widely regarded as the gold standard for establishing causality (Lum and Koper, 2024; Sherman et al., 1998). However, studies without these features can still provide meaningful insights, particularly when they use strong measurement strategies or mixed-methods approaches. Based on a coding framework adapted from previous studies, 30.3% (n = 61) of articles were designated methodologically strong as they featured random assignment, quasi-experimental designs, or other high-validity methods. Another 62.7% (n = 126) were classified moderate as, despite lacking fully counterfactual designs, they incorporated multiple methods or repeated measures. The remaining 7.5% (n = 15) were categorized as limited in rigor due to reliance on single-point observational data or the omission of basic safeguards against confounding variables.
Despite their emphasis on outcomes, most studies gave limited attention to the real-world application of instructional knowledge. Defined as measurable changes in officer behaviour or community outcomes, including reduced use-of-force incidents, improved complaint profiles, or shifts in crime patterns, these effects are vital to determining whether education and training prepare officers for the complex and unpredictable nature of frontline policing. Despite their importance, only 24.4% (n = 49) of studies in this category included operational data. The remainder (75.6%; n = 152) relied on indirect proxies, including attitudinal shifts, knowledge gains, or simulated performance outcomes (e.g. surveys, scenario tests, proficiency exams). While valuable, these measures do not necessarily translate into sustained or observable changes in field practice.
Regarding the impact of instruction, most studies (87.1%; n = 175) reported positive outcomes, defined in relation to two broad, often competing, logics of police work: crime control, which emphasizes enforcement, surveillance, and deterrence, and community service, which prioritizes legitimacy, procedural justice, and public trust. Positive outcomes encompassed improvements in both domains, including reduced use of force (Rydberg and Terrill, 2010), enhanced accuracy and efficiency during high-stakes encounters (Anderson and Gustafsburg, 2016), and increased use of noncoercive, problem-solving strategies (Paoline and Terrill 2007). Other gains involved improved officer preparedness and attitudes toward specific challenges, such as interviewing and intelligence-gathering (Price and Roberts, 2011), hostage extraction (Avdija, 2018), harm reduction (Saucier et al., 2016), de-escalation (White et al., 2021), suspicious activity detection (Regens et al., 2017), and health and safety issues like work-related stress (Carleton et al., 2018) and needle-stick injuries (Strike and Watson 2017).
A smaller subset of studies (9.0%; n = 18) identified mixed effects where instruction produced both positive and negative outcomes. For instance, one study found overdose response training enhanced officers’ knowledge of symptoms but simultaneously reinforced stigmatizing views of people who use drugs (Winograd et al., 2020). Only 4.5% (n = 9) reported negative effects, including increases in authoritarian attitudes (Simon, 2023), use of force (Rockwell et al., 2021), and organizational cynicism in the form of diminished job satisfaction (Hallenberg and Cockcroft, 2017) and a strengthened ‘code of silence’ around misconduct (Donner and Maskály, 2023).
The next most prevalent themes were Evaluations (12.7%; n = 43) and Descriptive (12.7%; n = 43). In the first instance, rather than generating new data through interviews, surveys, or experiments, studies classified as Evaluations drew on theoretical insights or analyses of secondary materials (e.g. curricula, policy documents, prior research data) to assess the aims, content, and delivery of police education and training. 7 A central concern of research in this category was identifying the traits officers should possess and the most effective ways to foster them. Many publications critiqued prevailing methods as being outmoded or misaligned with the evolving demands of policing. Key concerns included the underutilization of university education despite evidence of its positive effects on performance, tolerance, and cultural competence (Roberg and Bonn, 2004; Stanko, 2020), insufficient training in problem-solving and procedural justice (Morgan, 2022), the limitations of lecture-based instruction (Cushion, 2022), the absence of public service values in basic training curricula (Cohen, 2021), and inconsistent standards across jurisdictions (Gardiner, 2021).
Rather than evaluating outcomes or efficacy, studies designated as Descriptive offered detailed accounts of the content, delivery, organization, or institutional context of education and training. Topics included efforts to challenge dominant ideologies around race and gender (Huisman et al., 2005), the impact of COVID-19 on police academies (White et al., 2022), the prevalence and framing of human rights training (Engel and Burruss, 2004), and the scope of disability and mental health awareness instruction (Coleman and Cotton, 2014). Other studies described the development and delivery of specialized training programs on topics including CPR (Hirsch et al., 2012) and missing persons search-and-rescue (Ferguson and Gaub, 2023).
The final three themes examined the views, influence, and motivations of police personnel. Officer Perceptions accounted for 10.3% of publications (n = 35). These studies explored how recruits and officers perceived specific training topics (e.g. cybercrime [Cockcroft et al., 2021], equity and diversity [Israel et al., 2017], intimate partner violence [Blaney 2010], mindfulness and mental health [Eddy et al., 2021]), delivery methods (e.g. hands-on, learning [Oliva and Compton 2010], virtual simulations [Comiskey et al., 2021]); and the general value of education and training (Edwards 2019; Wolfe et al., 2022). For instance, one study found focus group participants preferred interactive, applied approaches over traditional lectures and hierarchical formats (Olivia and Compton 2010).
Officer Effects (4.4%; n = 15) focused on how officers’ backgrounds, traits, and predispositions shaped their engagement with training and broader professionalization efforts. This included analyses of how entrenched beliefs (e.g. hyper-masculinity, colour-blind ideologies) can obstruct the internalization of procedural justice and inclusivity principles (Hoang et al., 2023; Rawski and Workman-Stark, 2018), as well as studies examining predictors of training success (e.g., personality traits, cognitive ability, sociodemographic factors [Compton and Chien, 2008; Helfgott et al., 2023; Plybon et al., 2024]). While this literature underscores how individual variation can mediate learning outcomes even within standardized instructional environments, no studies integrated these psychological and demographic variables with organizational or cultural dynamics, limiting their ability to capture the complex, multi-level nature of professional learning.
Finally, Officer Participation, which examined why officers choose to pursue specialized training, comprised just 1.2% of the sample (n = 4). Motivations included professional development goals, prior occupational experience, empathy, educational attainment, and concern for community welfare. Topics addressed included cybercrime (Holt and Bossler, 2012), crisis response (Compton et al., 2017), and procedural justice (Somers and Foster, 2023).

Concluding discussion
By offering a detailed overview of the contours of scholarship on police education and training, this review illuminates key insights, trends, and omissions which can inform future research and assist in the development and implementation of more efficacious professionalization strategies. Most significantly, the findings highlight the need for a more holistic understanding of police professionalization that considers how individual traits, pedagogical strategies, institutional contexts, and organizational cultures jointly influence the impact of professional development. Informed by ecological systems theory and occupational socialization research, this orientation conceives of education and training, not as discrete interventions, but interdependent mechanisms within a broader ecosystem of learning. As the review suggests, the success of instruction depends as much on the content delivered as on how it is received, enacted, and sustained within officers’ professional lifeworlds.
Empirically, the review finds that, while the volume and disciplinary breadth of research has grown markedly over the past two decades, scholarship remains conceptually fragmented and methodologically uneven. Most notably, research continues to privilege training over education, emphasizing procedural skills and operational readiness while giving limited attention to cognitive, ethical, and analytical development. This disparity reflects, and risks reinforcing, a narrow conception of professionalization that values technical proficiency over reflective judgment. A more integrated framework makes clear why this imbalance matters. In neglecting education, instructional efforts may underprepare officers to navigate ambiguity, exercise discretion, and resist the pull of insular occupational cultures, all of which are necessary to serve diverse communities with fairness and accountability (Paoline and Terrill, 2007; Roberg, 1978).
Methodological patterns reveal additional constraints that limit the field’s ability to support evidence-based reform and respond to shifting operational demands. Chief among these is the dominance of quantitative studies. While statistical techniques assist in gauging the effects of instruction, they are incapable of capturing officers’ lived experiences, obstructing understanding of how learning is internalized, resisted, or adapted over time. Accordingly, a greater share of qualitative, longitudinal, and mixed-methods studies is required to pierce the ‘black box’ of police learning and attend to the intersecting effects of cumulative experience, peer influence, and institutional climate (Chan et al., 2003). An ecological perspective clarifies that such omissions are not simply gaps but blind spots that hinder theory development and the design of constructive interventions.
Furthermore, despite the prevalence of experimental and quasi-experimental studies, the literature exhibits a dearth of rigorous research designs and field data, raising concerns about internal validity and the real-world relevance of education and training initiatives. The limited use of counterfactuals or comparison groups complicates efforts to determine whether observed changes in officers’ attitudes, knowledge, and performance result from instruction or external factors, restricting the ability to draw firm conclusions (Neyroud and Weisburd, 2014). Moreover, because most studies examine instructional effects in controlled settings rather than in active-duty contexts, it remains difficult to judge whether learning endures or translates into practice. Such conditions limit the extent to which interventions can be shown to produce lasting improvements in conduct or decision-making. Addressing these gaps requires closer alignment with evidence-based policy principles and greater methodological diversity to strengthen the empirical foundation for curricular and policy reform.
Substantively, the review reveals growing emphasis on education and training modules aligned with consensual, community-serving, and problem-oriented approaches to policing (e.g. procedural justice, de-escalation, mental health awareness). While these emphases reflect broader shifts in public expectations and policy priorities, several emerging domains of police work, including extremism and radicalization, youth justice, human trafficking, cybercrime and digital forensics, and technology-assisted policing (e.g. crime mapping, predictive analytics, social media monitoring), remain underrepresented despite their increasing importance in criminological scholarship and public debate. When viewed through a multi-level model of professionalization, such conditions reveal significant disjuncture between what is demanded of contemporary officers and what is institutionally prioritized or academically examined.
Accompanying these methodological and empirical omissions, the review exposes important conceptual and thematic gaps in how police learning is understood. Despite seeking to pinpoint the effects of instruction on cadets and officers, few studies considered the role of instructors, trainers, or organizational leaders in shaping the integration of formal instruction into the everyday realities of police work. Such neglect is unfortunate as successful professionalization hinges on, not only what is taught, but on whether the broader occupational environment enables or obstructs the application of learning (Tucker, 2015). The character and inclusivity of the learning process itself also received limited attention. Although a handful of studies assessed attitudes towards certain instructional approaches (e.g. lecture-based formats), research did not examine whether officers’ learning preferences are reflected in the design or delivery of educational and training programs. Additionally, despite increased attention to diversity vis-à-vis community relations and support, studies failed to consider whether professionalization efforts accommodate the varied needs and backgrounds of officers. Together, these omissions limit understanding of how professionalization is supported, or undermined, across different roles, ranks, and institutional settings. Accordingly, an integrated framework can help clarify these dynamics, highlighting how misalignments between training content and organizational culture, including the persistence of cynicism, insularity, or entrenched silence around misconduct, can render instruction ineffectual or devoid of operational relevance. 8
Collectively, the review’s findings reinforce the need for treating education and training not as standalone interventions, but as components of a broader ecology of police learning and development. Such an approach reveals how individual dispositions, instructional designs, institutional structures, and cultural logics co-produce the meanings and effects of professionalization. Importantly, doing so can assist in exposing the multiple, interacting factors that shape whether learning persists and influences practice, illuminating both how professionalization occurs across different domains and the conditions that strengthen or blunt its impact. In this sense, the framework, not only clarifies existing research patterns, but also identifies where gaps remain and where efforts to strengthen professional competence are most vulnerable to breakdown.
The review also sets out an agenda for refining how police learning is studied and understood, one that calls for methodological pluralism, comparative inquiry, and greater attention to field dynamics, including how learning is enacted, disrupted, and reconfigured in everyday police work. Ultimately, building a more unified knowledge base on police professionalization requires scholars to connect domains that have too often been treated in isolation. This involves linking pedagogical content with organizational practice, educational theory with occupational culture, and short-term instructional outcomes with long-term institutional change. Doing so can both facilitate more robust academic inquiry and inform policy and curricular reform, enhancing the preparation of officers for the complex and evolving demands of 21st-century policing.
Limitations and future research
As the first extensive review of research concerning police education and training, this study naturally has its limitations. While ensuring sample publications were reliable, sound, and externally validated by established scholars, the focus on peer-reviewed journal articles may exclude other valuable knowledge sources. Future studies could, thus, expand their focus to include other academic work (e.g. edited volumes, book manuscripts, conference proceedings) and grey literature (e.g. government reports, policy briefs, working papers, unpublished reports, theses and dissertations). Additionally, despite providing access to a wide array of high-quality, peer-reviewed sources, Web of Science’s indexing practices underrepresent scholarship in more specialized, applied, and practitioner-oriented outlets. Consequently, the disciplinary distribution reported in the review may reflect the contours of the database as much as the underlying research field. Subsequent studies could address this constraint by incorporating additional databases or conducting targeted searches across relevant journals not indexed in Web of Science. Another limitation is the exclusive focus on English-language publications and research from Australia, Canada, the United Kingdom, and the United States. Expanding the scope to include non-English work and studies from other regions could yield a richer and more comprehensive and diverse set of results. Finally, given the increasingly multilateral nature of crime prevention and control, the focus on formal policing agents could be extended to consider how professionalization occurs under public, private, and plural auspices (Brodeur, 2010). Nonetheless, it is hoped that this review stimulates further research into emerging initiatives and challenges concerning police education and training.
