In recent years, there’s been an explosion in television shows and movies related to crime scene investigation, including CSI, Dexter, and NCIS, among others. Not surprisingly, the intriguing work of collecting, documenting, and analyzing evidence from crime scenes has captured the hearts and minds of popular culture, and becoming a CSI can be a fulfilling career choice for born problem-solvers.
Some related professions to crime scene investigators (CSIs) include evidence technicians (ETs), crime scene technicians (CSTs), crime scene analysts (CSAs), forensic investigators (FAs), scenes of crime officers (SOCOs), and criminologists.
So how does a person typically become a CSI? According to the US Bureau of Labor Statistics (BLS 2023), CSIs may start as police officers and receive practical training through academies, supervised investigations, and on-the-job mentoring. Others choose to pursue a post-secondary two- or four-year degree in crime scene investigation, forensic science, criminal justice, or a related discipline. Some even decide to get their degrees while working for a police department, forensics lab, or private investigations firm, an option facilitated by the increasing number of convenient online CSI programs.
Read on to discover what to expect from a certificate or degree program—including online (i.e., distance-based) and on-campus options at crime scene investigator colleges and program accreditation and professional certification information.
As with many careers, crime scene investigation (CSI) and forensic science jobs have overlapping responsibilities. CSIs collect and document evidence from a crime scene and draw conclusions to solve one or a series of related crimes.
On the other hand, an individual with law enforcement and forensic science backgrounds may be responsible for collecting and analyzing crime scene evidence and serving as a key witness in a legal case.
One distinctive difference between these two positions is education. According to O*NET OnLine (2022), an occupational data source sponsored by the US Department of Labor, becoming a crime scene investigator requires graduating from a police academy and, for some leadership positions, earning an associate’s or bachelor’s degree in criminal justice.
According to the BLS, forensic scientists typically need a bachelor’s degree in natural science and on-the-job training in law enforcement and laboratory procedures. Licensing and certification are optional but highly recommended to help forensic scientists earn the highest credibility in their profession.
The time spent outside or in an office is a second consideration between CSIs and forensic scientists. The BLS showed that criminal investigators split their time between desk and fieldwork, while forensic scientists work almost exclusively in laboratory settings. Because crime happens at all hours of the day, so does the work of CSI professionals, who can be called in when necessary to investigate a crime scene.
And while it’s true that forensic scientists and intelligence analysts work more regular hours, by comparison, forensic scientists may have to be on call to collect evidence if a CSI is not available and perhaps also analyze it if the testing needed is time-sensitive (BLS 2022).
Salary is the final difference between CSI and forensic scientists. The BLS (2022) shows that the median annual salary for private detectives and investigators is $59,380 per year compared to $61,930 for forensic scientists.
It’s important to note that while these two positions are distinct, they share some responsibilities and work environment settings. The certificate and degree programs featured here provide professionals with many career pathways to pursue one or both of these CSI careers.
Luckily for people with employment, familial, or other time commitments, there’s a growing array of online certificates and degrees for aspiring CSIs. These programs have more flexible course scheduling since students can log in from anywhere with a decent internet connection for lectures, assignments, case studies, and exams.
Becoming a crime scene investigator (CSI) involves hands-on empirical experience and rigorous didactic instruction. The International Crime Scene Investigators Association (ICSIA) reports that while some CSIs start as police officers, others may pursue an associate’s or bachelor’s degree in a field such as criminal justice, forensics, crime scene investigation, or a related field. ICSIA adds that only the largest (and busiest) police departments typically have full-time CSIs. In contrast, smaller, more rural areas may have other law enforcement personnel taking on the CSI responsibilities as they arise.
Who should enroll in an online CSI certificate program?
The entry-level certificate programs can be ideal for those interested in CSI work who have graduated from high school or completed their GED. Online certificate programs can also behoove police officers working in smaller, more rural departments far from college campuses.
For more advanced or specialized certificates, programs may have additional admissions requirements, including years of work experience (e.g., on a police force); an admissions essay; official transcripts of previous schooling; and a background check. Since these are not degree-awarding programs, they typically do not require tests like the SAT. Finally, these programs can assist CSIs in seeking certification since many certifying agencies need between 48 and 144 hours of approved coursework (e.g., International Association for Identification).
