When you hear the term “detective,” you might think of the fast-paced, well-groomed characters from television series. True detective work demands extreme patience, rigorous investigation, and unwavering ethics; it is very different from the glamorous portrayals in the media. The process of solving cases can take months or even years, during which time a lot of time is spent sifting through files, documents, and photos.
On top of that, solving cases may expose investigators to potentially dangerous people and situations. Notwithstanding the difficulties, though, working as a detective can be fulfilling because it offers the intense sense of accomplishment that results from cracking cases and giving victims closure.
Despite the overlap in their areas of expertise, private investigators (PIs) and police detectives are two different professions. Police detectives usually obtain investigative experience through their work in law enforcement and become detectives as a promotion through the agency. This is according to the Bureau of Labor Statistics (BLS 2022).
At work, they might interview witnesses or suspects, look through documents, gather and meticulously record evidence, write reports, watch subjects at work, secure crime scenes, obtain arrest warrants, assist in apprehending offenders, and also testify as experts in court.
In contrast, private investigators, or PIs, are citizens who usually require state licensure. They gain experience in obtaining legal, financial, and personal information about their clients through surveillance and background checks. They also participate in missing person tracking, snooping for hints in documents, and speaking with relevant individuals. Detectives can focus on corporate malpractice, insurance fraud, computer forensics, and other areas.
There are a hoard of professional courses you can do, and your scope is equally varied. Keep reading to learn about the salary detectives draw and the qualifications, training, and personality needed to enter this field. Here is everything you need to know about how to become a detective.
Skills To Become a Detective
Most prosperous detectives are inquisitive, meticulous, and diligent. Perseverance may also be crucial because solving crimes isn’t always a straight line or a quick process. The Bureau of Labor Statistics states that the following abilities are critical for successful detective work:
Communication skills: When speaking with witnesses, victims, and possible offenders, detectives need to pay close attention to what they are saying, ask the right questions, and be aware of nonverbal cues.
Decision-making skills: Detectives need to be able to make decisions quickly and calmly, especially when someone’s life is in danger or when acting quickly can lead to the discovery of information that can help solve a crime.
Curiosity: Skilled investigators possess an innate ability to solve puzzles and can consider potential reasons behind a crime as well as determine the means of commission.
Perseverance: As mentioned earlier, solving a crime can take several months or even years. Crimes go unsolved occasionally, turning into cold cases that may be reopened years later, particularly with the development of forensic technologies like DNA testing.
Resourcefulness: Although detectives always need to be quick on their feet and adhere to protocol, they also need to be able to solve crimes by using their intuition and the resources at hand.
How To Become a Detective?
There are several ways to become a detective or private investigator (PI), but they all involve a consistent mix of classroom learning and real-world investigative experience. If you want to know how to become a detective, then this is one standard way:
Step 1: Complete your four years of high school
At this point, prospective detectives are advised to cultivate critical thinking, deductive reasoning, and inductive reasoning. To obtain practical experience in the field, some students might look for volunteer opportunities. They can do it through their local police departments, community organizations, or federal agencies.
For instance, high school students who are interested can enroll in the FBI’s week-long Future Agents in Training (FAIT) program. Similarly, eligible high school and college students can apply for the Pathways Internship Program offered by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).
Step 2: Complete degree program in criminal justice, criminology, sociology, or related field
Many police academies require at least some college to qualify. Whereas some police academies may be able to accept prospective police detectives directly. Eileen Carlin is a state coordinator for Rasmussen College’s School of Justice Studies and a 20-year law enforcement veteran. According to him, most departments prefer detectives with two- to four-year college degrees.
Step 3: Complete a police academy and gain investigative experience
The next step for someone who wants to work as a police detective is to enroll in a police academy. This is an option that can be more profitable than working as a private investigator (PI).
The qualifications for a police academy differ depending on the department and area, but applicants must be US citizens, be at least eighteen years old, have a driver’s license, have never been convicted of a felony, and have some college experience.
Note that most state as well as federal agencies require a minimum of four years of undergraduate study. Typically lasting six to eight months, police academy programs provide specialized training in the use of firearms, patrol procedures, ethics, self-defense, writing reports, CPR and first aid, physical fitness, and emergency response.
Aspiring detectives can enhance their resumes by pursuing advanced training and responsibilities in investigative units after graduating from the academy. Homicide, surveillance, fraud, cybercrimes, financial crimes, and missing persons are among the different investigation branches.
Step 4: Private investigator’s (PIs) licensure and on-the-job investigative experience
Prior to receiving a license, private investigators frequently need to have investigative experience gained through on-the-job training. Before being issued a license to operate, a prospective PI must first fulfill the eligibility standards of their home state, pass an exam, and finish additional state-mandated requirements. The number of hours required for this type of work varies depending on the state.
After receiving their full license, the PI may choose to focus on specific investigation fields, such as litigation support, insurance claims, cybersecurity, and criminal investigations. An online resource for investigators, Pursuit Magazine (2022), notes that 46 states (as well as certain cities) require a license for private investigators to practice, and it offers a useful table of state-by-state private investigator licensure policies.
Step 5: Police detective exam for professional certification
Both private investigators and police detectives can obtain certifications. For investigators with a focus on criminal defense or negligence, the National Association of Legal Investigators (NALI) offers the Certified Legal Investigator (CLI) credential.
Candidates for the CLI program must pass an exam with a minimum score of 70%, finish a 1,000-word research paper on investigations, and have at least five years of full-time experience (or qualify through appropriate academic coursework). Every three years, CLIs must complete 50 hours of continuing education (CE) to keep their certification.
For investigators who specialize in security, ASIS International offers the Professional Certified Investigator (PCI) certification. Candidates must have five years of investigative experience (two of which must be in case management) and a high school diploma to be eligible. People’s knowledge of case management, investigative techniques and procedures, and case presentation is tested on a 140-question exam.
Step 6: Local credentialing
State-specific requirements may differ for becoming a detective. The procedures to enter the state’s detective division may differ as well. Because most states have distinct standards for becoming police officers.
Generally, some police departments only accept a GED or high school certificate. Others demand a two- or four-year college degree, as well as certain college courses. For instance, you need a high school degree or GED to work in the Los Angeles Police Department Detective Bureau. Here, the first promotion after completing officer training is detective or sergeant.
However, candidates must have completed two years of military service or 60 college credits to be considered for employment with the New York Police Department. Candidates from Dallas, Texas, between 21 and 44, must have a 2.0 GPA and 45 semester credits (college-level).
In contrast, candidates in Miami, Florida, must obtain a GED or a high school diploma and pass the Florida Basic Abilities Test (FBAT), a law enforcement exam. To put it briefly, state requirements for becoming a detective differ greatly. Moreover, it is advised that prospective candidates check their eligibility by contacting their local government offices.

Additionally, because of compliance regulations and technological advancements, ongoing training might be required. Certain departments might also conduct ongoing research, design, and implementation of improvement strategies. This is done to improve the caliber of their investigative methods and procedures.
Some of these specializations or divisions, which are typically headed by lieutenants, captains, or commanders, are listed below:

How Long Does It Take to Become a Detective?
In general, there are many different routes to becoming a police detective. But it can take five to eight years to advance from police officer to detective after earning a high school degree or GED. The BLS (2022) states that to become a detective, a person must complete high school or earn a GED. Most will do so by earning an associate or bachelor’s degree in criminology, criminal justice, sociology, psychology, or a similar discipline.
Moreover, passing physical exams, background checks, and other requirements is necessary for prospective officers to be considered as competitive applicant in a police department. Candidates may occasionally attend a police academy to receive additional training after being hired as police officers. Academies differ in duration depending on the department, city, and state. Basic police training takes place in Portland, or, for 16 weeks, while it takes place in San Jose, CA, for 0 weeks.
In addition, prospective detectives need to work as police officers for at least three years after completing a police academy to be promoted to detective. Officers who want to advance in the police department must pass exams and/or review their service history.
How Much Do Detectives Earn?
It’s crucial to remember that four of the states with the highest salaries in the US also have the highest cost of living. To illustrate the point, the Missouri Economic Research and Information Center (MERIC 2023) discovered that among the top fifteen most expensive states are Alaska, the District of Columbia, Maryland, Hawaii, and Washington. In contrast, Mississippi, Oklahoma, Kansas, Missouri, and Alabama were the five states with the lowest cost of living.
Ultimately, over the next ten years, job growth rates for private investigators and police detectives are anticipated to be comparable. For example, in 2022, the Bureau of Labor Statistics (BLS) predicted that employment for police investigators (BLS) would increase by 3% and for investigators (PIs) by 6% between 2021 and 2031. This growth is almost equal to the average growth predicted for all occupations during that period (5%).
