Detailed Guide for

Forensic Science Technicians in Los Angeles County

May also be called: Crime Lab Technicians; Crime Scene Technicians; Criminalists; Evidence Technicians; and Forensic Analysts

Specialties within this occupation include: DNA Analysts; Fingerprint Experts; Forensic Ballistics Experts; and Handwriting Experts

What Would I Do?

Due to the popularity of television programs that prominently feature this occupation, Forensic Science Technicians occupy a unique place in the public's imagination. Do Technicians, however, in reality do what is portrayed on the small screen? They do, but in less glamourous circumstances. Forensic Science Technicians collect, identify, classify, and analyze physical evidence related to criminal investigations. They perform tests on weapons or substances, such as fiber, glass, hair, bodily fluids, and tissue, to determine the significance to the investigation.

Many Forensic Science Technicians prepare written findings and displays for court presentations and may be called upon to present fair and impartial court testimony as a qualified expert witness. Sometimes they work closely with other scientific investigatory agencies to coordinate findings or to seek alternative methods of analysis. Technicians may also conduct research into new methods and procedures of forensic science analyses.

DNA Analysts perform forensic human DNA tests and analyses of evidentiary samples, such as blood, saliva, or semen, encountered in the course of criminal investigations. Analyses of these samples provide a genetic blueprint that is unique to each person, which is then used to try and match with a suspect. Proper handling and storage is essential to preserve DNA test samples.

Fingerprint Experts use laboratory techniques to analyze fingerprints collected at the crime scene. Sometimes they do the collecting as well: "lifting" prints off various surfaces, photographing, and then exposing them. They must learn how light and chemicals work in tandem to expose the print for analysis.

Forensic Ballistics Experts analyze the bullets and weapons found at crime scenes. They can determine, among other things, the proximity between the weapon and the victim, the trajectory of the bullet, and the type and model of the weapon used. Ballistics Experts can often tell the difference between a homicide, a suicide, and an accidental shooting.

Handwriting Experts analyze various printed or handwritten documents, such as wills, personal letters, ransom notes, and income tax returns, to determine the documents' age and authenticity.

Tools and Technology

Forensic Science Technicians use a variety of tools including biological evidence collection kits, cameras, footprint lifters, laboratory scalpels and scissors, lasers, magnifiers, and specimen collectors. They also use technology such as analytical or scientific, charting, e-mail, and graphics software.

Working Conditions

Forensic Science Technicians work under a variety of conditions. Most work indoors, usually in well-lit, clean, and ventilated laboratories, while others may have to split time between a laboratory and crime scenes. They often work regular hours, but may be called upon to help in pending investigations during any hour of the day. They may experience distress and unpleasantness from collecting evidence from crime scenes. Forensic Science Technicians often are exposed to human bodily fluids and weapons. However, these working conditions pose little risk if proper safety procedures are followed.

Forensic Science Technicians employed by public agencies are usually included in the agency's law enforcement collective bargaining unit.

Will This Job Fit Me?

The job of Forensic Science Technician may appeal to individuals who enjoy activities that involve working with ideas and require an extensive amount of thinking.

How Do I Qualify?

Education, Training, and Other Requirements

A bachelor's degree is generally the minimum educational level that employers will consider for a position as a Forensic Science Technician. The degree should be in forensic science, criminalistics (with an emphasis in chemistry), criminal justice, or one of the physical or biological sciences, such as biochemistry, physics, or biology. In California, the completion of a degree in one of these majors should be supplemented by 8 semester or 12 quarter units of general chemistry and 3 semester or 4.5 quarter units of quantitative analysis in order to be eligible for employment at a public agency. Moreover, those Forensic Science Technicians interested in specializing in a certain forensic field ought to major in a closely related program; for instance, prospective DNA Analysts should major in biology or chemistry.


Entry-level Forensic Science Technicians should have, at the minimum, one year of experience in a laboratory setting. Novice Technicians usually work under the direction of a senior Technician, until they have demonstrated the ability to work on cases independently.

Early Career Planning

Prospective Forensic Science Technicians should take biology and chemistry classes as well as English, computer science, mathematics, and public speaking. Many institutions in California also offer Regional Occupational Programs (ROPs) in forensic science. To find an ROP program near you, go to the California Association of Regional Occupational Centers and Programs Web site.

Continuing Education

Although there is no requirement for Forensic Science Technicians to continue their education, they should continue to be aware of innovations in evidence collection and laboratory techniques in order to stay current in their occupation.
