Which science subjects do I need to study forensic science in the UK?

Many forensic science courses in the UK need only one science subject, chemistry or biology, while some want both, so entry varies by course. The course then branches into areas such as toxicology, forensic chemistry, molecular biology and criminology, so a firm base in the sciences helps.

To study forensic science in the UK, many courses need only one science, chemistry or biology, while some want both, so entry varies by course. A solid base in both gives you the best chance of keeping up once the course widens into other areas.

Core scienceChemistry or biology (some courses want both)
Specialist scienceMolecular biology, forensic chemistry, toxicology, forensic entomology
Law and crimeLaw and its application through criminology, crime scene study, criminal analysis

Where the Course Can Lead

  • Police forces, investigation agencies, law enforcement and customs.
  • Roles such as analytical chemist, toxicologist and crime scene investigator.
  • Scientific laboratory technician and biomedical scientist positions.

My Advice

If you studied biology and chemistry in school, you are in a good position. If one is missing, speak to the admissions office about a foundation year or bridging route before you apply, and check each course page for its exact subject rules.
