What Does a Forensic Scientist Do?

At crime scenes, they meticulously analyze, document and collect evidence such as weapons, fingerprints and bodily fluids. In the lab, forensic scientists specialize in various areas such as DNA analysis, toxicology, firearms, fingerprint analysis or controlled substances, among others.1 Their tasks may vary depending on the organization they work for, but they commonly include the following:1

Aid in criminal investigations

Gather evidence, analyze data, and provide expertise in various forensic disciplines.

Document findings

Write reports detailing findings and methods, including photography, sketching, observation recording and evidence collection.

Catalog and preserve evidence

Carefully document, label and store all collected crime scene items for evidence integrity and traceability in investigations and legal proceedings.

Articulate findings

Explain findings and methods to lawyers, detectives and other law enforcement personnel.

Testify in court

Testify as an expert witness about their findings and methods.

Reconstruct crime scenes

Analyze physical evidence, witness testimonies and forensic data to recreate the sequence of events leading up to and following a crime.

A forensic scientist employs scientific methodologies to probe crimes and scrutinize evidence. They utilize analytical reasoning and technical proficiency to identify potential suspects, aid in the construction of compelling cases, and operate effectively in both laboratory settings and crime scenes.

What Experience and Education Does a Forensic Scientist Need?

Knowing how to become a forensic scientist is essential for those aiming to enter the field. Here’s a typical educational path and steps for starting this career:

Prioritizing high school coursework in subjects such as biology, chemistry, physiology, statistics and mathematics can be a great start toward a career in forensic science. Enrolling in Advanced Placement (AP) courses can also be advantageous. Additionally, gaining practical experience through volunteering or internships at relevant institutions like police, medical labs or similar organizations can be a valuable step in preparation.3

Forensic science technicians typically require a bachelor's degree in a physical science such as chemistry, biology or forensic science. Forensic science programs may specialize in a specific area of study, such as toxicology, pathology or DNA analysis. Many prospective forensic science technicians obtain an undergraduate degree in the natural sciences before pursuing a master's degree in forensic science.4 

Newly recruited crime scene investigators and forensic scientists will undergo training alongside experienced scientists to familiarize themselves with the proper procedures and techniques for collecting and documenting evidence.4 On-the-job training is required both for those who investigate crime scenes and for those who work in labs.4 Training lasts anywhere from six months to four years, depending on the forensic specialty.4

While numerous licenses and certifications exist to facilitate the professional development of forensic science technicians, they are generally not obligatory for entry into the field. The diversity of credentials may fluctuate considerably due to variations in standards and regulations across different jurisdictions.4

By following this educational and experiential path, you can prepare yourself for a career as a forensic scientist, equipping you with the knowledge, skills and practical experience necessary to pursue this critical field.

Where Do Forensic Scientists Work?

Forensic scientists usually work behind the scenes, either in a laboratory or crime scene environment.1 They work closely with law enforcement agencies, legal teams, attorneys and other professionals to gather and interpret evidence that can be used in criminal investigations and court proceedings.


Crime testing laboratories

Forensic science technicians often work in crime labs and able to work day, evening or night shifts.6

Crime scenes

Forensic science technicians may be required to travel throughout their jurisdiction (cities, counties or states) and work outside in all types of weather to help gather evidence from crime scenes.7

National government

The U.S. Drug Enforcement Administration (DEA) hires forensic scientists to perform fingerprint analysis and forensic computer investigators to support DEA agents and other law enforcement personnel.6

Local and state government/law enforcement

Local and state police departments, such as city and state police, employ forensic scientists to process evidence and assist in the investigation of crimes, including reconstructing the crime scene using various techniques such as diagrams and trajectory analysis.8


Hospitals employ forensic nurses to provide trauma care and collect physical evidence from crime victims.8 This career route requires a nursing degree and specialized training.

Due to COVID-19, data from 2020 to 2023 may be atypical compared to prior years. BLS calculates the median using salaries of workers nationwide with varying levels of education and experience. It does not reflect the earnings of GCU graduates as forensic science technicians, nor does it reflect the earnings of workers in one city or region of the country or a typical entry-level salary. Median income is the statistical midpoint for the range of salaries in a specific occupation. It represents what you would earn if you were paid more money than half the workers in an occupation, and less than half the workers in an occupation. It may give you a basis to estimate what you might earn at some point if you enter this career. Grand Canyon University can make no guarantees on individual graduates’ salaries. Your employability will be determined by numerous factors over which GCU has no control, such as the employer the graduate chooses to apply to, the graduate’s experience level, individual characteristics, skills, etc. against a pool of candidates.
