What Does a Crime Scene Investigator or Technician Do?

Are you considering a career as a crime scene investigator (CSI) or forensic science technician? Professionals in this field aid criminal investigations by collecting and analyzing evidence on-site. This includes taking photographs, making sketches, recording observations, determining what items should be collected, and cataloging evidence. If you possess skills in math, science, problem-solving, critical-thinking, and communication, and aren’t upset by criminal or even violent acts, this may be a career worth pursuing.

Forensic science technicians often have to work in a wide variety of conditions, including all types of weather. They also tend to spend long hours in laboratories and/or offices. Additionally, these professionals must be able to work constructively with law enforcement personnel and other specialists to solve crimes.

Employment opportunities for crime scene technicians are fairly limited. As a relatively small occupation, the U.S. Bureau of Labor Statistics (BLS) reported there were only 17,200 jobs available in the United States in 2019. While the career field is expected to grow by 14% by 2029, this will only result in approximately 2,400 additional positions overall.

Choosing a Crime Scene Technician or Investigator Program

Online vs. On-Campus

Forensic science and crime scene investigation students are not limited to traditional, on-campus learning. Many colleges and universities offer online alternatives. Distance learning is generally ideal for students who already work full-time or have restrictive responsibilities at home. The flexible scheduling options can make earning a degree much more attainable.

Those interested in a career as a forensic science technician or crime scene investigator will have little trouble finding online degree programs at every level.

While online programs offer flexible scheduling and can be completed at a slower pace, there are some drawbacks you should be aware of. The primary problem with distance learning is the lack of fact-to-face interaction with instructors and peers. Some institutions address this by offering hybrid degrees. Students enrolled in a hybrid program complete the majority of their coursework online, but must periodically visit the campus for short residency sessions. These workshops allow for some in-person instruction, hands-on experience, and networking.

Job Placement Assistance

Because the forensic science and crime scene investigation field is fairly small, it can be difficult to find employment after completing the necessary education requirements. Even with a projected increase in availability, graduates should expect significant competition for most jobs.

Fortunately, many educational institutions attempt to make the transition from student to professional a little easier. While employment is never guaranteed, many programs provide current and past students access to career-related resources.

Post graduate job placement assistance programs vary, but often include one or more of the following:

  • Interview Preparation
  • Resume Development
  • Career Coaching Services
  • Internship Opportunities
  • Job Fairs

It’s a good idea to research potential forensic science and crime scene investigation programs thoroughly to verify that job placement assistance is available before enrolling. Many institutions also publish employment rate statistics, showing the percentage of graduates who find employment after graduation.


How long does it take to complete a forensic science program?

The length of time necessary to complete a forensic science program will depend primarily upon the type of degree sought. In general, associate and master’s degrees take full-time students approximately two years to complete.
