If you’re interested in working with crime scenes and evidence to make sure that the guilty person gets their day in court, then you may have just the right mind to be a Crime Scene Investigator.

What is a Crime Scene Investigator?

In order to find a criminal, police need evidence.

Where does the evidence come from, you may ask?

Crime Scene Investigators of course.

These are the men and women who painstakingly comb through crime scenes in order to find the smallest of clues, whether that be a fingerprint, a gum wrapper, or blood, the crime scene investigator does it all.

You’ll help collect, analyze, and submit evidence to a crime laboratory.

You’ll also make detailed reports on everything found on the scene, as well as speak to authorities about anything mentioned in the reports.


On a day to day basis, Crime Scene Investigators may have to perform many of the following:

  • Communicate with law enforcement about crime scenes, protocol, and procedures
  • Make sure all materials are available and ready to use
  • Clean and maintain equipment
  • Ensure all procedures are followed according to law
  • Collect weapons-related evidence
  • Handle human bodily fluids such as blood, as well as DNA
  • Package and transport evidence


The average salary for a crime scene investigator in the United States is around $67,000 a year.

Those that have more education, skills, experience and knowledge of the career will likely make more money.

Where you work also has a major role in how much you make.

If you work for a smaller city, you will likely make less than one with more crime attached.

To make the most out of your career, try and find ways to ensure that you are constantly educating yourself.

This way, you can be on your way to making up to $74,000 a year.

How to Become a Crime Scene Investigator

Step 1Earn Your Bachelor's Degree

In order to become a Crime Scene Investigator, you are going to need to obtain a Bachelor’s degree.

This degree should be in either biology, chemistry, criminal justice, physics, law or forensic science.

Check out the college that you are interested in to see if they offer a major in forensic science, as this is a new field of study.

The benefits of pursuing a degree in forensic science can lead you toward success in your future.

You’ll be able to focus on areas of the job that you want, rather than studying other things that may come up with majors such as criminal justice or chemistry.

This could give you a leg up in the career opportunity department.

Even if you don’t want to obtain a degree in forensic science, you’ll still be on your way to becoming a wonderful Crime Scene Investigator.

Step 2Become an Intern

Although this is a voluntary experience, it can help in tremendous ways.

You’ll be able to obtain some hands-on experience and learn all about what it takes to be a good Crime Scene Investigator.

Internships should take up to a year, and you can even start while you are still in school!

The thing about internships, though, is that they are highly competitive.

If you are looking to pursue on, you may want to start looking as soon as you enroll in college, this way you can be sure you’ll have a spot.

Some internships will pay you between $35,000 and $50,000 a year.

Step 3Obtain Your Master's

Again, this step is voluntary.

You don’t have to get a Master’s degree, but if you are looking to create a lifelong career as a Crime Scene Investigator, then why not go for the gold?

A Master’s can take around two years to finish.

You can get a Master’s degree in forensic science, science and criminalistics, forensic biology, and even biomedical forensic science.

It may be smart to start working before gaining a Master’s, as the experience will boost your probability to obtain employment once you are doing with your schooling.

Step 4Become Certified

After all of that education, you’ll also need to make sure that you are certified in at least one of the following:

American Board of Criminalistics- This certification is for people who want to focus on drug analysis, fire debris, hairs, fibers, paint, and polymers.

American Board of Forensic Document Examiners- If you’re interested in looking through documents, papers, and other materials, this might be a great place to become certified.

International Society of Forensic Computer Examiners- This certification will give you the ability to examine computers for evidence.

International Association for Property and Evidence- This certification will allow you to handle evidence.

Association of Fire Arm and Tool Mark Examiners- With this certification, you’ll know how to look at guns and tools for evidence.

American Board of Psychiatry & Neurology – With this certification, you can walk away with the knowledge of psychiatry and the brain.

There are so many certifications that come along with this job, ask around at your school or workplace to see what other options are available to you.


Most employers won’t even look at your resume if they don’t see at least a Bachelor’s degree under your education.

The most relevant areas that you are going to want to study for this career are forensic science and crime scene investigations.

Although, it is possible to become a Crime Scene Investigator with another type of degree, such as law, criminology, biology, chemistry and so on.

A Bachelor’s degree can take around four years to complete for full-time students.

In order to get the best available training, you will want to take courses in human anatomy, physics, legal studies, forensics, psychology, criminal justice, chemistry, and investigation.

Having a Bachelor’s degree prepares you for the career that you are looking for, but if you want to become even more educated, you could always earn your Master’s degree.

A Master’s degree in forensic science or a related field can gain you access to even more lucrative jobs within law enforcement.

With both a Master’s and Bachelor’s degrees you can choose to either work independently or with a law enforcement agency.

Another two years will be added to your education if you go for your Master’s degree.

In order to be accepted into a Master’s degree program, you will need to have experience in the work field.

Typically, those that are going for their Master’s degree have had at least one year of Crime Science Investigator training.

An important feature that you will want to be aware of when going for your Master’s is that the program is accredited with the Forensic Science Education Programs Accreditation Commission.

This way, you know that you are doing work legally in the state in which you live.

If you know that you have a specialization, or feel that you are more interested in a certain area of crime scene investigation, it’s possible to obtain a specialized Master’s degree.

Some of the areas that are offered include financial crimes, digital crimes, forensic psychology, and forensic chemistry.
