- Crime-scene investigators, properly known as forensic science technicians, collect and analyze physical evidence as part of the criminal-investigation process. They may conduct tests on weapons or on fibers, hair and body fluids. They document their findings in reports and often give testimony when cases go to trial.
- A forensic science technician's job generally requires at least a bachelor's degree in a science-related field, usually chemistry, biology or forensic science. College coursework should include biology, genetics, microbiology, botany, biochemistry, calculus and statistical procedures.
- Despite the growing popularity of degree programs in forensic science, some criminologists recommend a chemistry degree for people interested in crime-scene investigation careers, because of the degree's broad applicability.
- Knowledge of criminal-justice and legal procedures may be helpful for a forensic science career, as well. Most colleges and universities offer undergraduate courses in law, criminal justice and criminal investigation, often in their government, sociology or criminal-justice departments.
- Some law-enforcement agencies may require forensic science technicians to be licensed police officers, but most do not.
