In the United States, certification and licensure requirements for law enforcement officers vary significantly from state to state.Policing in the United States is highly fragmented, and there are no national minimum standards for licensing police officers in the U.S.
The agency that establishes standards for police officer selection, training, licensure, certification, and suspension/decertification is called the police officer standards and training (POST) commission in 15 states (as of 2004),including California and Arizona. In other states, the certification body goes by a different name, such as the Kentucky Law Enforcement Council, Massachusetts Municipal Training Council, Indiana Law Enforcement Training Board, Maryland Police and Corrections Training Commissions, Alaska Police Standards Council, and the Michigan Commission on Law Enforcement Standards.
Although the Wickersham Commission established by President Herbert Hoover called for the establishment of standards for police officers (including minimal training requirements, selection standards, physical standards, and police training before and during service), state standards for selecting and training police began to be adopted only in the latter half of the 20th century. Early advocates of professionalization and reform of police included August Vollmer of the Berkeley Police Department and O. W. Wilson of the Chicago Police Department.
The California Commission on Peace Officer Standards and Training (the first body to use the acronym "POST") was established in 1959.In the same year, New York enacted the New York Training Act, which established an advisory council to make recommendations on police training to the governor. In addition to California and New York, the states of Montana and Minnesota established their POST commissions in 1959. New Jersey, Oklahoma, and Oregon followed two years later. The 1967 Katzenbach Commission (President's Commission on Law Enforcement and Administration of Justice) and the 1973 National Advisory Commission on Criminal Justice Standards and Goals both encouraged establishment of a POST commission in each state to set minimum standard standards for selection, training, and certification. Between 1959 and 1976, 43 state police officer standards and training bodies were established. At the behest of the International Association of Chiefs of Police, the National Association of State Directors of Law Enforcement Training (NASDLET) was established in 1970; the association changed its name to the International Association of Directors of Law Enforcement Standards and Training (IADLEST) in 1987. The last states to establish commissions were Tennessee, West Virginia, and Hawaii.
Standards for police officers are not uniform; different states have different requirements.However, the International Association of Directors of Law Enforcement Standards and Training (IADLEST), a cooperative association of leaders of various state police certification and licensing programs, has published a recommended set of "model minimum state standards" in 2004. However, there is a substantial variations in standards. More progressive police departments place greater emphasis on accreditation.
A study in the year 2000 found that the minimum number of police training hours varied from 320 to 800.In some states, the minimal training time for officers set by state regulation is shorter than the training time to become a licensed barber, cosmetologist, or manicurist, although many police departments have training requirements in excess of the state minimum.
In some states, the standards and certification body also directly runs the police academy.A Bureau of Justice Statistics (BJS) study found that as of 2013, about 4.5% of U.S. state and local law enforcement training academies were operated by a state POST commission. The 2013 BJS study found that academies run by state POST agencies and colleges/universities were more likely to use a "nonstress" training model (based on "academic achievement, physical training, and a more relaxed and supportive instructor–trainee relationship") as opposed to a "stress" training model (a military-style training regime based on "intensive physical demands and psychological pressure"). This contrasts with academies run by police forces, which more often are based on a stress model. Although state POST commissions run only a small proportion of police academies, POST commission-run academies have larger faculty sizes: an average of 30 full-time instructors and 81 part-time instructors, as of 2006, according to a BJS report.
In some states, police officers are required to undergo continuing education ("in-service training")that is reported to and tracked by the state certifying body. Experts favor in-service training because it offers insights to police officers on newer research and best practices. However, in some states, in-service training requirements are minimal, and is frequently delivered online rather than hands-on. Moreover, in some states where continuing police education is mandatory, funding for training and mechanisms for tracking compliance are lacking. Massachusetts requires police officers to undergo 40 hours of in-service police training each year, one of the nation's highest requirements, but lacks a statewide body overseeing compliance, and a 2019 state auditor report indicated that up to 30 police departments in the state might be out of compliance with the mandate.
Police training curricula vary widely.Many police academies use military- or paramilitary-style training models; Rosa Brooks, an expert on policing training at Georgetown University Law Center, argues that this training model is harmful and contributes to the militarization of police.
Between 2014 and 2017, many state legislatures adopted legislation requiring police officers to receive crisis intervention and deescalation training,which has been demonstrated to reduce police use of force. As of 2017, however, 34 states do not require deescalation training for all police officers, and other states require minimal training in deescalation (for example, 1 hour per year in Georgia). While local departments can train officers in deescalation in the absence of a state mandate, many departments do not do so because of a lack of funding or trained instructors, and because of cultural attitudes among police and police leaders, such as the belief that such training is not necessary or is a criticism of policing itself. As of 2018, 27 states and District of Columbia require police officers to undergo training on interacting with individuals with mental, substance use, or behavioral disorders.
Because there are no federal standards for officer firearms training, standards vary by state.In most states, officers do not receive firearms training sufficient for the proficient handling of guns in real-world scenarios. For police cadets, a total of 40 hours of initial firearms training is required in Georgia, Illinois and Indiana; 52 hours in Utah; 66 hours in Missouri; 80 hours in Florida; and 90 hours in Washington state. After initial graduation from police academy, most officers are qualified in minimal firearms proficiency only once or twice annually, and firearms skills degrade rapidly. Experts attribute these training gaps to a significant number of accidental shootings (unintentional discharges) by police officers. An Associated Press report found that there were 1,422 unintentional discharges by officers at 258 law enforcement agencies of all sizes between 2012 to December 2019, and that these unintentional discharges caused injuries (to officers, suspects and bystanders) 20% of the time and caused death 8% of the time.
Experts, such as police instructors and researchers, similarly identify training of U.S. police officers on the use-of-force techniques as inadequate.A two-year study conducted by the Force Science Institute, a Minnesota-based police research and consulting firm, found that "skills like using a baton or taking down an aggressive offender deteriorate dramatically within two weeks."
Police training in the United States has often been plagued by pseudoscience, junk science, and questionable science, with various common elements of police training being underpinned by misinformation, unsubstantiated claims, assumptions, and anecdotes. —based on the assumption that if a suspect is "any closer than 21 feet, the person could charge before an officer could unholster their gun"—is not scientific, and its creator has said the drill should not be taken literally; nevertheless, the drill is still commonly taught in police training as a science and has been used as an argument to justify police use of force. The American Society of Evidence-Based Policing and other experts proposed evidence-based policing and the creation of an "independent, nonpartisan body providing research and education to police departments" based on rigorous evidence.Many police practices taught in training are not evidence-based or supported by empirical research. For example, the "21-foot Tueller Drill"
Most states require a person to be certified before he or she may be hired as a police officer; as of 2020, four states, including Massachusetts, lacked a statewide police certification system.As of 2009, 23 states with a certification process exempted certain personnel (usually elected sheriffs, and less commonly, police chiefs, state police officers, and reserve police officers) from the certification requirement.
In a minority of states, police certifying bodies also certify other public safety employees, such as correctional officers (23 states), parole officers and probation officers (21 states) and police dispatchers (15 states).
By 1998, 11 states' commissions lacked decertification authority—the power to revoke a license to work as a police officer—largely because of police union opposition. By 2016, six states (Massachusetts, New York, New Jersey, Rhode Island, California and Hawaii) still lacked decertification authority. In a 2009 survey, almost all states reported that they had the authority to revoke an officer's certificate upon conviction of a felony; a smaller number of states reported that they had the authority to revoke an officer's certificate upon conviction of any misdemeanor or for certain misdemeanors. Entities in 36 states reported that they could administratively revoke an officer's certificate for police misconduct; and entities in 31 states reported that they had the authority to temporarily suspend an officer's certificate. States differ dramatically in the number of officers decertified. At least since the late 1990s, Georgia has been the most active state in decertifying "problem" officers. Over the period 2015–2019, Georgia decertified 3,239 officers, Minnesota decertified 21, and Maryland decertified only one.
In some states, the decertification process has drawn scrutiny because a lack of speed and transparency.In some states, a law enforcement agency must report the firing (or the firing for cause) of a police officer to the state certifying commission; in other states, a law enforcement agency only needs to report to the state certifying commission when an officer is arrested or convicted of a crime (or, in some states, a felony); and in some states, there is no notification obligation even under those circumstances. For example, in Maine, "Agencies must tell the state about officers arrested or convicted of a crime, as well as those fired or allowed to resign for misconduct." In Montana, law enforcement agencies are not required to report officer misconduct, but must notify the state commission of a termination of an officer within 10 days. In Indiana, there is "no requirement for agencies to inform the state about officer arrests or noncriminal misconduct allegations."
An Associated Press (AP) investigation in 2020 found that 17 officers were decertified in Iowa from 2018 to June 2020, mostly after being convicted of felonies, domestic violence, or certain other crimes in which removal is mandatory under Iowa law. 1⁄2-year period, only a single Iowa officer had been "decertified for improper police work alone" (an officer who filed false reports and made an arrest without probable cause). Iowa enacted a law in June 2020 to strengthen the decertification process by, among other things, requiring the Iowa Law Enforcement Academy Council to decertify officers who engage in "serious misconduct" (such as fabricating evidence or repeatedly using excessive force) and by requiring police departments to report details of an officer's misconduct to the Iowa Law Enforcement Academy Council within 10 days after the officer resigns or is terminated.Although removal is mandatory is such cases, the AP found that it was routine for a year or more to elapse, following officers' convictions, before the Iowa Law Enforcement Academy Council filed petitions seeking decertification, and that it was common for another year to go by for decertification to become final (after a hearing before an administrative law judge and a vote by the council). During the 2
In 1999, IADLEST, with funding from the U.S. Department of Justice's Bureau of Justice Assistance, established the National Decertification Index (NDI), a database of decertified officers.As of 2005, only 13 states participated in the national decertification database; by 2018, that number rose to 43. NDI has received no federal funding since 2005, and is privately maintained. The database does not contain the reasons for the decertification; a hit on a decertified officer's name will refer the person conducting the query to the specific agency that decertified the officer. Law professor Roger L. Goldman, an expert on police certification, notes that "Since the grounds for decertification vary greatly among U.S. states, the fact of decertification does not mean the officer is automatically ineligible to be an officer in the state to which he or she has moved. For example, in some states, conviction of a felony is the only grounds for decertification; whereas, in other states, the commission of specified misconduct, such as filing a false police report, could trigger decertification." As a result, an officer whose license is suspended in one state for misconduct, or even for conviction of a crime, may be able to find a police job in another state with laxer requirements. In its 1998 report Shielded from Justice: Police Brutality and Accountability in the United States, Human Rights Watch recommended that all states have decertification authority; that federal legislation should be adopted to create a database of state POSTs' records "so that 'problem' or abusive officers are not allowed to obtain law enforcement employment in a neighboring state"; and that decertification procedures "should be reinvigorated and fully funded." A 2015 AP investigation uncovered numerous incidents of police officers who were terminated or resigned from a police agency after being accused of sexual misconduct, were then rehired by a different policy agency, and were subsequently accused again of misconduct.
A detective is an investigator, usually a member of a law enforcement agency. They often collect information to solve crimes by talking to witnesses and informants, collecting physical evidence, or searching records in databases. This leads them to arrest criminals and enable them to be convicted in court. A detective may work for the police or privately.
A police officer, also known as an officer, policeman, or a policewoman is a warranted law employee of a police force. In most countries, "police officer" is a generic term not specifying a particular rank. In some, the use of the rank "officer" is legally reserved for military personnel.
A fire marshal or fire commissioner, in the United States and Canada, is often a member of a state, provincial or territorial government, but may be part of a building department or a separate department altogether. Fire marshals' duties vary but usually include fire code enforcement or investigating fires for origin and cause. Fire marshals may be sworn law-enforcement officers and are often experienced firefighters. In larger cities with substantially developed fire departments the local fire departments are sometimes delegated some of the duties of the fire marshal.
In law enforcement in the United States, a gypsy cop, also known as a wandering police officer, is a police officer who frequently transfers between police departments, having a record of misconduct or unsuitable job performance. The term is slang, referencing the stereotypical nomadic lifestyle of the Romani people, pejoratively "Gypsies".
A police academy is a training school for police recruits. It is also known as a law enforcement academy, college, or university. It involves a variety of background checks. These include examinations, physical requirements, medical requirements, legal training, driving skills, equipment training, and firearm training for law enforcement recruits. The academy prepares recruits for the law enforcement agency they will be assigned to upon graduation.
The West Virginia State Police is a state law enforcement agency in the United States that provides police services to the residents of West Virginia. It is the fourth-oldest state police agency in the US, and was created in the second extraordinary session of the West Virginia Legislature on June 19, 1919, as a result of uprisings surrounding organized labor in the coal and mine industries.
The Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA) is a credentialing authority (accreditation), based in the United States, whose primary mission is to accredit public safety agencies, namely law enforcement agencies, training academies, communications centers, and campus public safety agencies.
Law enforcement in the United States is one of three major components of the criminal justice system of the United States, along with courts and corrections. Although each component operates semi-independently, the three collectively form a chain leading from an investigation of suspected criminal activity to the administration of criminal punishment.
The Columbus Division of Police is the main policing unit for the city of Columbus, Ohio, in the United States. It is the largest police department in the state of Ohio, and among the twenty-five largest in the United States. It is composed of twenty precincts, and the chief of police is Tom Quinlan. Special units of the Columbus Division of Police includes a Helicopter Unit, Canine Unit, Mounted Unit, Community Response Teams, Marine Park Unit, and Special Weapons and Tactics Team (SWAT).
The Kentucky State Police (KSP) is a department of the Kentucky Justice and Public Safety Cabinet, and the official State Police force of the Commonwealth of Kentucky, responsible for statewide law enforcement. The department was founded in 1948 and replaced the Kentucky Highway Patrol. The department's sworn personnel hold the title State Troopers and are addressed as Trooper and its nickname is The Thin Gray Line.
Police accountability involves holding both individual police officers, as well as law enforcement agencies responsible for effectively delivering basic services of crime control and maintaining order, while treating individuals fairly and within the bounds of law. Police are expected to uphold laws, regarding due process, search and seizure, arrests, discrimination, as well as other laws relating to equal employment, sexual harassment, etc. Holding police accountable is important for maintaining the public's "faith in the system". Research has shown that the public prefers independent review of complaints against law enforcement, rather than relying on police departments to conduct internal investigations. There is suggestion that such oversight would improve the public's view on the way in which police officers are held accountable.
A security guard is a person employed by a government or private party to protect the employing party's assets from a variety of hazards by enforcing preventative measures. Security guards do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, looking for signs of crime or other hazards, taking action to minimize damage, and reporting any incidents to their clients and emergency services, as appropriate.
The FBI National Academy is a program of the FBI Academy for active U.S. law enforcement personnel and also for international law enforcement personnel who seek to enhance their credentials in their field and to raise law enforcement standards, knowledge, and also cooperation worldwide. The FBI National Academy is held four times a year, when up to 250 candidates go through a 10-week course.
The Worker Protection Standard is intended to protect employees on farms, forests, nurseries, and greenhouses that are occupationally exposed to agricultural pesticides.
In South Carolina, a State Constable is a law enforcement officer who is either a uniformed or plainclothes law enforcement officer employed by one of the departments of the state government, a retired police officer, or a volunteer reserve police officer. Officers may be variously described as "State Constable", "Special State Constable", "Department of Public Safety (DPS) Special Constable" and "Magistrates' Constable". State Constables are appointed by the Governor of South Carolina, and regulated by the South Carolina Law Enforcement Division.
The history of law enforcement in the United States includes many efforts at police reform. Early efforts at police reform often involved external commissions, such as the Wickersham Commission, that spelled out reforms but left to the police to implement them, often with limited success.
Lexipol LLC is a private company based in California that provides policy manuals, training bulletins, and consulting services to law enforcement agencies, fire departments, and other public safety departments. In 2019, 3500 agencies in 35 U.S. states used Lexipol manuals or subscribed to their services. Lexipol states that it services 8,100 agencies as of March 2020. Lexipol retains copyright over all manuals that they create, even those modified by local agencies, but does not take on the status of policymaker. Critics note that a decision made by Lexipol becomes policy in thousands of agencies and that there is little transparency into how the policy decisions are made.
The Minnesota Board of Peace Officer Standards and Training (POST) is an administrative body of the State of Minnesota, that sets regulations and controls the training and licensing of police officers. The Minnesota legislature replaced the Minnesota Peace Officer Training Board (MPOTB) with POST in 1977. Minnesota was the first U.S. state to introduce an occupational licensing system for law enforcement officers.
