What is Criminalistics? Why Study It?

Search For Schools

The criminal justice system in America is the overarching establishment through which crimes and those who commit them are discovered, tried, and punished. This includes all of the institutions of government aimed at upholding social order, deterring and mitigating crime and sanctioning those who violate the law, such as law enforcement, and the court and jail systems.

Criminology and criminalistics are two subsets of the criminal justice system. Criminology relates to the study and prevention of crime—typically with behavioral sciences like sociology, psychology and anthropology. Criminalistics refers to a type of forensics—the analysis of physical evidence from a crime scene.

While criminology has preventative components, criminalistics comes into effect only after a crime has been committed. A criminalist applies scientific principles to the recognition, documentation, preservation, and analysis of physical evidence from a crime scene. Criminalistics can also include crime scene investigations. The Bureau of Labor Statistics (BLS) classifies criminalists as forensic science technicians. Most professionals regard criminalistics as a specialty within the field of forensic science.

What Do Criminalists Do?

Criminalists use their knowledge of physical and natural science to examine and analyze every piece of evidence from a crime scene. They prepare written reports of their findings and may have to present their reports in court. A criminalist is not involved in determining the guilt or innocence of an accused individual; their job, rather, is to present an objective analysis of the evidence.

There are several key skills that criminalists need to be successful in their work. They must be detail-oriented and have excellent written and verbal communication skills. They should also have strong critical-thinking and problem-solving skills and a solid background in science, statistics, physics, math, and ethics. Finally, criminalists should be comfortable testifying in court.

Most of a criminalist’s work is performed in a laboratory unless they specialize in crime scene investigation. Their job typically includes recognizing what information is important, collecting and analyzing evidence without contaminating it, and organizing all information and evidence coherently.

Criminalistics has many fields of specialization. Specialties include, but are not limited to:

  • Alcohol and drugs
  • Arson
  • Blood and tissue spatter
  • Computer forensics
  • DNA
  • Explosions
  • Serology (examining and analyzing body fluids)
  • Toxicology
  • Firearms and tool marks
  • Trace evidence
  • Wildlife (analyzing evidence against poachers)

As long as crimes continue to be committed, there will alway be work for criminalists. A criminal will always leave evidence, no matter how minute, according to forensic scientist and “Father of Criminalistics” Paul L. Kirk:

“Wherever he steps, whatever he touches, whatever he leaves, even unconsciously, will serve as silent evidence against him. Not only his fingerprints or his footprints, but his hair, the fibers from his clothes, the glass he breaks, the tool mark he leaves, the paint he scratches, the blood or semen that he deposits or collects – all these and more bear mute witness against him. This is evidence that does not forget. It is not confused by the excitement of the moment. It is not absent because human witnesses are. It is factual evidence. Physical evidence cannot be wrong; it cannot perjure itself; it cannot be wholly absent. Only its interpretation can err. Only human failure to find it, study and understand it, can diminish its value.”

Who Employs Criminalists?

The BLS (Oct. 2017) predicted that openings for forensic technicians would increase by 17 percent in the decade preceding 2026, which is more than double the average for all occupations nationally (7 percent). Technological advances have made forensic information increasingly essential in the courts and criminalists with a master’s degree are expected to have the best opportunities.

The biggest employers of criminalists are governmental agencies, such as those below.

  • Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)
  • Central Intelligence Agency (CIA)
  • Drug Enforcement Administration (DEA)
  • Environmental Protection Agency (EPA)
  • Federal Bureau of Investigation (FBI)
  • Medical Examiners/Coroners
  • Military
  • Police departments
  • U.S. Customs

Other employers include private companies, educational institutions, and crime laboratories.

For most positions, criminalists must pass drug tests and background investigations. Although criminalists are not obligated to be licensed, most choose to obtain credentials and certifications from various professional organizations.

Featured Criminalistics Programs

Most entry-level criminalist positions require bachelor’s degrees in biology, chemistry, forensics, or other natural or physical science, but some positions require a master’s degree. Due to advances in technology and methodology, continuing education is necessary.

When choosing a school, it is essential to that the school is accredited, and if so, what agency certified it. Accreditation is a process by which an independent agency evaluates the quality of the curriculum and faculty. While criminalistics does not have a specific accrediting agency, the Forensic Science Education Programs Accreditation Commission (FEPAC)—the most prominent accreditation entity in this field—does certify forensic science programs. Furthermore, there are several recognized, regional accreditation entities which evaluate universities as a whole and have received approval from the U.S. Department of Education’s Council for Higher Education Accreditation (CHEA). Below are a few schools that offer accredited criminalistics programs.

Metropolitan State University of Denver, Department of Chemistry

The Metropolitan State University of Denver offers a bachelor’s degree in chemistry with a concentration in criminalistics. The program has two tracks, the first of which requires one semester of physical chemistry and two internships in criminalistics. The second track requires one internship and a full year of physical chemistry studies, which allows the student to earn the certification of the American Chemical Society (ACS). The tracks require 97 or 107 credit-hours, respectively. Students may also opt for a bachelor’s degree in criminal justice with a minor in criminalistics, which requires 144 credit-hours.
