Forensic scientists require a bachelor’s degree in forensic science or a natural science if they wish to work in law enforcement.

However, many rural agencies may only require a high school diploma. Technicians who wish to work in a laboratory require a bachelor’s degree either in forensic science or natural sciences such as biology or chemistry.

Students going for a forensic science degree should make sure that their coursework includes mathematics, biology, and chemistry.

Forensic Science Programs Online

There are a number of forensic science programs available online. These programs include master’s programs, graduate certificates, and also non-credit courses.

The major advantages of online programs are the flexibility and the convenience they offer to students. Students may also save on additional costs for travelling and textbooks, which are usually associated with on-campus programs.

Many new developments are taking place in online education and well reputed schools are now offering their courses online, which helps to make education accessible to more people.


Forensic scientists require on-the-job training before they are eligible to work independently. New crime scene investigators work as apprentices under experienced investigators. Through apprenticeship, they learn appropriate procedures and methods of gathering and recording evidence.

Forensic scientists learn laboratory specialties on the job as well, and the length of laboratory training depends on the specialty. DNA analysis training takes six to twelve months, while firearms training may last for three years or more.
