Detective Careers – Investigator Careers – Detective Job Info
Detective careers and Investigator careers are in high demand and will continue to be for years to come. There is a big variety of investigator jobs in the law enforcement career field, thus creating an increased need for qualified detectives.
Detectives, also known as investigators, are plainclothes law enforcement officers who gather facts and collect evidence for criminal cases. For the most part, detectives are looking to solve specific types of crime, like: robberies, car thefts, fraud and homicides. However, some detectives are assigned to inter-agency task forces to combat crime. They conduct interviews, examine records, observe the activities of suspects, and participate in raids or arrests. Detectives are assigned cases on a rotating basis and work on them until an arrest and conviction is made or until the case is dropped. Investigators in State and Federal levels usually specialize in investigating one type of violation, such as homicide or fraud.
Most common reference to a detective is one on a local level and is associated with a sworn-in police officer who passed the detective exam, thus receiving a promotion. Detectives, or investigators, on a state and federal level are usually known as agents or special agents.
Detective Requirements
Most detectives and investigators must be U.S. citizens (born or naturalized). They usually start as police officers and wait until they are eligible to take the detective exam. After successful completion they may receive the promotion. Police officers usually become eligible for promotion after a probationary period ranging from 6 months to 3 years. However, certain departments, and most state / federal agencies, do require additional “fire power” – see Education and Training below for more info.
Education and Training
Nearly all detectives must successfully complete the educational and training requirements of a police officer first. Some police departments, and nearly all State and Federal investigation agencies, require significant academic and on-the-job experience. If one doesn’t have on-the-job experience on a State or Federal level an education equivalent is accepted – usually a minimum of a Bachelor degree.
Certain police departments may grant one a promotion based on one’s performance on the job. This is usually prevalent in smaller departments, but recently even the smallest law enforcement agencies started to add an educational requirement – some college credits, Associates degree, or a Bachelor degree – which must be completed at the time of promotion or within a predefined time frame (ex. 4 years from time of promotion). Take advantage of the fact that many agencies pay all or part of the tuition for officers to work toward degrees in criminal justice, police science, administration of justice, public administration, criminology, and others.
Depending on where one works, additional training may be required with the position of Detective or Criminal Investigator. Majority of new investigators gain the most training through performing the actual work and by collaborating with seasoned detectives.
Detective Salary
According to the Bureau of Labor Statistics, in May 2006, median annual earnings of detectives and criminal investigators were $58,260. The middle 50 percent earned between $43,920 and $76,350. The lowest 10 percent earned less than $34,480, and the highest 10 percent earned more than $92,590. Median annual earnings were $69,510 in Federal Government, $49,370 in State government, and $52,520 in local government.
The salary information will be updated here with a new release of salary statistics by the Bureau of Labor Statistics, so don’t worry about years of difference – it’s just a formality. Salaries for the current year are not that far off, but for the most accurate information call or visit the agency in question. Many police departments and county / state / federal agencies offer salary, benefit, and hiring info right on their website.
Career Opportunities
Detectives and Investigators have many career opportunities that can be obtained through tenure, training, and education. Investigation of murder, fraud, robberies, car-thefts, terrorism threats, drug trafficking, human trafficking, and other types of crime is contingent on which level you work at (local, State, or Federal), and which task force you’re assigned to.
Some detectives choose to become Private Detectives, or Private Investigators (PIs), after they finish working for their respective agencies. PIs are usually contracted to solve personal matters, including: unsolved murder or missing person cases, infidelity, insurance fraud, and more. Private investigation is different in scope from typical detective work, and therefore, shouldn’t be assumed to mean the same thing.

Very useful site, as it is my dream to become a detective. Just wondering, what qualifications would you need to become an investigator or detective as I am considering studying Psychology at university but of course would change according to what was needed. Thanks!
Well, the requirements are pretty much the same as listed above, but the article on How to Become a Detective? may help. Psychology is a good field, and depending where you’re thinking of working it may be a very good way to get you through the day as a detective.
What is the difference between a homicide detective and crime scene investigator? I am currently majoring in criminal justice as a freshmen, as you know from before, and am wondering if I should minor in anything special. I am not looking to be a forensic scientist and stay in a lab all day, I would like to arrive at crime scenes, collect evidence, interview witnesses, investigate, and so on. When watching “The First 48″ it says “crime scene” on the back of their jackets sometimes in episodes as they search houses and so on for evidence. I basically want to do what they do. I live in Massachusetts and am not sure if it differs by each state.
I wrote a post about the difference between a detective and a crime scene investigator?. It should be of some help.
The requirements for a CSI may differ by state, but based on what you would like to do – collect evidence, investigate, and etc. – you might like the crime scene investigator track which is much different in scope from a detective profession.
Are Detectives on call?
Yes, most departments try to accommodate their investigative units with “normal” shifts, but like with anything in life, most shifts are not your typical 9-5. You may work extended hours AND be called in after only a short respite. This may vary in severity department by department.
If I were to become a Detective and I want to earn more pay than the average? Is it the more education I have the more I would get paid?
That would be partially true. Some departments treat detective status as “the end of the road” for requirements — “all is equal now”.. kind of mentality. While others continually seek more education AND agency training. And still, there is nepotism and cronyism within police departments, where education may be a threat rather than an asset. It all depends where you end up pursuing your career.
Okay, I’m a high school senior, and I eventually want to be an FBI Special Agent. I got accepted to Penn State and I’m going to major in Criminal Justice. Now I also want to join the Marine Corp after which is why I’m enrolled in the ROTC program. After I get out of the military, I would like to become a detective to gain more experience. Is there a way to shorten the probationary period for eligibility to take the detective exam so that I won’t be to old by the time I’m ready to apply to the FBI?
Probably not, although there may be Veteran’s Preference applied when you do. Also, you don’t need to be a detective before you join the FBI, nor do you have to join the Military. Granted these should help a lot, you still can apply with a strong Bachelor’s. Penn State is “the cream of the crop”.
This was a very helpful website and the information was very interesting. I enjoyed reading this and I’m major criminal justice after high school. Im finding the best colleges with the best curriculum to attend to major Criminal Justice. My goal is to get at least a 4.0 on my GPA. This information did benefit me and I highly appreciate it.
I’m a senior in high school and I want to be a crime scene investigator. I’m still not sure what college to attend to. Is a technical school a good option to get my degree? Like everst college and west wood university? Do they accept their degree?
I would recommend better schools than those. Perhaps a traditional college education (but online, if you prefer) I highly recommend that the school you go to is regionally accredited and doesn’t carry a negative connotation. Research on Google, for example, about different schools and any potential problems. Nationally accredited schools are okay, too, but they are a FAR second choice.
Thanks, i really appreciate it.
I’m a sophomore in High school, and I wanna go into criminal justice and be a cop and eventually be promoted to detective. But I cant see myself handling a tough situation on the job. Should I go into a different career?
You still have time to test your “situation” handling skills. I wouldn’t write-it-off just yet.
Ok so this explains alot but do you have to go to college to become a part of this career? Do you have to have a min degree? I mean I know their is alot of training im a high school graduate and trying to get into the career of a detective/investigator? and don’t know where to start does this require you to have a college degree?
Chris, the “do you have to go to college” part depends on the police department. Some departments require college education (60 semester credit hours/Associate’s, or Bachelor’s) and some don’t, but may require you to obtain a certain level of college education while on the force. There might be an educational requirement imposed on moving up to the detective position, which usually means that you have to take on a detective exam, but not always. A good read would also be the “Police Officer Career” on my site — find it under “Careers” at the top.
This website is very helpful. Thanks for all the information and comments you have posted. Like everyone else that has left you a comment, I am very interested in the Criminal Justice field, more so on being a detective. If I am understanding this information right, depending on the agency or department I choose to apply for, I might not need college? Also, I would not become a detective immediately? I would have to take an exam after a certain period of being on the force? I am currently in the Marine Corps, I am an Intelligence Specialist. I was looking into taking online classes for a Bachelor Degree but i wasn’t certain which college I should apply for. Also, with being in my certain job in the military and pursuing an online degree would put me above my peers? Thanks in advance!
Yes, you MIGHT NOT need college. You may have to wait (in most cases) to become a detective and an exam may be required. Sometimes, the promotion depends on merit, and yes, there are times when who you know trumps merit.
I don’t like calling it an online degree anymore… it’s a degree (period!)… what you will be doing is attending a college or university, but online, so make sure it is regionally accredited and that it is strong as an academic institution AND/OR has a strong degree program… people look at these type of things, just like what car you drive, how well-kept you are, and the friend you keep. Will the degree put you above your peers? that depends when you graduate, what marks you get, and how many people your age have similar degrees at the time. Good luck on your adventure!
Very helpful. Thanx.
Would becoming a detective/FBI special agent be too dangerous for a single mother? I’m debating on whether or not to live my dream career or choose a “safer” career. Keep in mind, I rather not sit behind a desk. I want to see some action, and solve cases! I chose to leave the military due to my beautiful boys but it’s time for me to move on with a career now that they are older (8 and 6). What do you think?
I think there’s an inherent danger working in law enforcement, but I also know that following one’s own dreams is what can make one truly happy. You’ve got a big decision to make here; one with many considerations. I wish you all the best.
this is so helpful for me cause I’m debating with detective or a CSI agent. or anything near that field i really want to know if you go to college in another state lets say penn state do they have different ways to teach classes for criminal justice than john jay?
they may have different teaching methods, course names, or even some courses, but both schools are just so top notch that it would be great to go to any one of them…
stefany i am currently a freshman / sophomore at kean university in union new jersey and i am a criminal justice major working on getting my B.A degree , i am looking to be a detective , me as a female would this be a good choice for me ?

Hello,
I am trying to decide which career will be best for me. I have many ideas in my head, but I have always been interested in mystery/thriller movies which has made me very interested in solving real mysteries. I a junior in high school and also taking college classes. My GPA has always been over 3.0. What does it take for a person to be a criminal investigator? Salary/hours? What are the disadvantages/advantages of the job?
thanks
I am currently a student and I am undecided about my major I want to be a homicide detective but I have two felonies but my crime is not violent, drug related or has nothing to do with children. Can someone please get back to me ASAP, ppl change and I want my chance to put back into my community but I have no idea whom to ask this question to.
Say if you have a felony on your record which I know that I didn’t do. Can you still become a private investigator or a detective?
Hello. My husband graduated and passed the state exam for police officer. But there is no jobs available in my region. He is working about 5 hours away from home. We have decided for him to go back to college and further his education. Problem is he doesn’t know what criminals justice career to study for. He wants something that is the least amount of time but will have demand and great salary…. Any comments would be appreciated.
