How to Become a Forensic Scientist

Do you like CSI? Is the idea of investigating crimes appealing to you?

What about the idea of working in a lab, assisting police solving cases?

Careers in forensic science have taken off in the past few years.

Forensic scientists are trained in the art of observation and use scientific investigation techniques to assist police solving crimes.

They are trained to perform several kinds of physical, chemical, and biological analyses to provide important information on crimes. From testing blood samples to examining chemical residue left at the crime scene, forensic scientists teams play an integral role in law enforcement.

So if a career in forensic scientists sounds like a good fit for you, read on to figure out how you can become a forensic scientist!

What Does a Forensic Scientist Do?

Forensic scientists work with law enforcement officers to analyze evidence left at the scene of the crime.

Forensic scientists are among the first to arrive on the crime scene, where they meticulously collect and catalog potential evidence.

They then move to the lab, where they use scientific techniques to classify unknown substances and objects and see how they relate to crime.

Among these techniques are the identification of foreign chemical, analysis of blood spatters, identifying the cause of death in a victim, and more.

Because their work is so science intensive, they must have a solid education in the sciences (biology, chemistry, physics, psychology) and also have a thorough understanding of the criminal justice system and its operation.

The field of forensic science has many subfields and specializations that are based on the kind of evidence examined, including:

  • Forensic anthropology: Examining human remains
  • Forensic pathology: Identifying injuries and causes of death
  • Forensic chemistry: Identification and classification of unknown chemical substances
  • Forensic psychology/psychiatry: Assessment of mental illness or other psychopathology
  • Digital forensics: Examining digital evidence (i.e. phones, networks, data comparison, etc.)
  • Forensic odontology: Examining dental remains and dental records for identification

In short, if there is a specific type of evidence, there is a forensic scientist trained to handle that kind of evidence.

Forensic scientists also use their knowledge to help police recreate the scene of the crime and perform DNA analysis on biological materials to identify victims and suspects. For example, a blood spatter analyst helps investigators recreate crime scenes based on the patterns of blood found at the crime science, or a forensic pathologist helps recreate the steps leading up to the death or injury of the victim.

Forensic scientists may also use their knowledge to examine ballistics and identify any weapons that may have been used. After performing their analyses, forensic scientists detail their findings in a report that is handed off to investigators.

Forensic scientists are the support wing of law enforcement who perform the difficult scientific leg work to give investigators the information they need to solve crimes. In that vein, forensic scientists are an extremely important part of law enforcement and play a crucial role in bringing criminals to justice.

Forensic Scientist Duties

Forensic scientists are trained in scientific theory and lab techniques.

  • Common duties of forensic scientists include:
  • Performing lab examination and analyses
  • Carrying out testing using lab techniques like infrared spectroscopy, mass spectroscopy, chemical separation, and more
  • Data entry of key findings in lab reports
  • Preparing written reports of findings
  • Examining and collecting evidence at crime scenes
  • Serving as experts witnesses in court
  • Maintaining and calibrating lab equipment
  • Acting as a liaison between lab teams and investigators
  • Developing and updating SOPs and quality standards for the lab

The higher position and the more specialized your degree, the more focused these duties will be on a particular type of evidence and analysis. Forensic pathologists, for example, perform duties focused on identifying the causes of death or injury in victims, while forensic psychiatrists focus on issues such as criminal motivation and criminal competency in a court of law.

Desirable Skills & Qualities of a Forensic Scientist

Forensic scientists are scientists first and foremost, so they must cultivate skills and work habits that help scientists succeed and discover the truth.

Attention to Detail

Forensic scientists must be extremely attentive to details and handle their lab duties in a meticulous manner. Often, a small detail can make or break a case, a detail that can be easily overlooked by a team that is inattentive to details. This includes having an exhaustive knowledge of lab and criminal proceedings. Additionally, the specific forensic techniques in the lab are extremely precise and must be carried out in a precise and accurate manner. A mix up in the lab could potentially ruin a sample or accidentally destroy crucial evidence.

Logical and Independent Thinking

Forensic scientists must be able to reason from available facts and examine how they fit into the larger case. This requires a substantial amount of critical thinking and skills in logic. Forensic scientists must be able to translate their lab findings into information that is relevant to the case and must know what kinds of inferences they can draw from the evidence. Like normal scientists, forensic scientists are aimed at discovering the truth and finding the truth requires the rigorous application of evidence and logic. Forensic scientists must also be able to set their prejudices aside and examine evidence in an objective and detached manner.

Written and Oral Communication Skills

As with virtually any profession, forensic scientists must have excellent written and oral communication skills. Forensic scientists must be able to take complex lab reports and translate their findings into accessible language for investigation teams. They must also be able to clearly and concisely communicate with other lab and law enforcement personnel. Typically, forensic scientists have a lot of evidence to dig through so they have to know how to communicate relevant findings and what relevance they have to the case.

High Tolerance for Stress

Unfortunately, forensic scientists will most likely have to deal with violent and psychologically disturbing crimes. Examining evidence from crime scenes (particularly violent crimes) can take an emotional toll. So, forensic scientists need to be able to separate their emotions from their work and be able to handle stress well. Too much stress clouds objectivity, so it is required that you can keep a clear mental state when in a stressful situation.

Additionally, forensic scientists often have to work under pressure and be sensitive to deadlines. When investigating a case, time is often of the essence, so good forensic scientists must be responsive to time constraints.

Forensic Scientist Education Requirements

Not just anyone can become a forensic scientist. Becoming a forensic scientist takes education and specialized training. Strictly speaking, forensic science is a broad field with many subfields and specializations (pathology, toxicology, psychiatry, etc). Becoming a specialist in one of these areas often requires a substantial amount of extra training and education. However, an entry-level position as a forensic science technician normally does not require substantial amounts of higher education.

In general, becoming a forensic scientist requires a 4-year degree from an accredited university. While there do exist specific degree programs in forensic sciences, it is not necessary to have such a degree to work as a forensic scientist. Many forensic scientists do have a background in a scientific field (biology, chemistry, psychology). The main thing employers will look for is experience working in a lab and familiarity with standardized procedures and techniques. Additional experience and knowledge in law enforcement is a plus, but not necessarily required.


In general, there are no legal requirements for accreditation and certification to work as a forensic science technician. You do not need a degree specifically in forensic science, but a degree in some scientific field is desired. Certain specializations may require legal certification, but these specifics differ depending on the state.

The Forensic Science Education Programs Accreditation Commission (FEPAC) has a list of universities that offer accredited programs in forensic science. While not necessary, a degree from a FEPAC accredited university will make the job hunt much easier as you will have a pedigree from a renowned university. Such accredited programs also tend to have very high education standards so you are guaranteed to get the highest quality training on up to date lab procedures and techniques. Accredited programs also tend to include on the job training. Often, forensic science programs include some courses in legal theory and criminal justice as well.

Aside from degree programs, there exist forensic science certification programs for undergraduates and graduates. Certification programs normally supplement a science degree with courses related to forensic science but fall short of a full-blown degree in forensic science. A certificate program in forensic science is a good option for those who want to add to their science degree.

What You’ll Study

Forensic scientists usually take a wide range of basic courses in the sciences. If you are working towards a degree specifically in forensic sciences, then these basic courses will be supplemented with courses geared specifically towards the application of scientific principles in a forensic lab setting.

Some course you will take in a forensic science program include:

  • General chemistry
  • Organic chemistry
  • Forensic pathology
  • Forensic toxicology
  • Crime scene processing
